? SAVE RESETTING WEAVING ELEMENTS
The constantly increasing number of weaving elements in the loom has
made the Portable Warp-Tying Machine a tremendous saver of time and
money. When the warp is woven out it is not necessary to remove the
weaving elements from the loom. The machine is moved into position
and tying-in is done directly behind the loom. Due to its compact form
and light weight, the machine is easily transported from loom to loom
throughout the weave shed.
Barber-Colman Portable Warp-Tying Machines have operated profitably
for mills with as few as 30 looms. Full time operation is not required to
show satisfactory savings. Here', are some typical examples: I-
SERVICE

The purpose of this machine is to tie-in a new warp to the ends of the old
warp at the loom without disturbing the settings of the weaving elements.
The machine is mounted on rubber tired, ball bearing wheels and can easily
be moved from loom to loom. It occupies a position in a loom alley similar
to that of a Hand Twister, but with a competent operator it has a production
equal to several Hand Twisters.
The machine successfully ties cotton and spun yarns. It will handle a
variety of fine to coarse counts with a few changes and adjustments in the
mechanism.
This machine is equipped with selector mechanism of both types; one for
selecting from an end-and-end lease, as on the Type 15 LS, and the other for
selecting from a flat sheet, as on the Type 15 I.C. The selecting mechanisms
are designed and incorporated in the carriage so that they may be readily
inter-changed. Change-over can easily be made in five to ten minutes,
depending upon the speed and skill of the operator. The comparatively few
parts for making the change-over are shown on the back page. Production
rates correspond with operations on the Type 15 LC and the Type 15 I.S.
This machine fills a need for those mills tying-in both flat sheet and end-and-
end lease warps, and where both the 15 LC and 15 LS machines cannot be
utilized to full capacity.
This machine is designed for tying-in rayon and other yarns constructed
from synthetic fibers in which leases are provided. It operates in a manner
similar to the Type 15 LC, but is equipped with an entirely new type of select-
ing mechanism. This mechanism selects warp threads from the leases to
insure as near perfect straightness as is possible to attain. The greater the
number of ends per warp, the higher will be the average hourly production.
This type is particularly well adapted for tying-in wool, worsteds, etc., where
it is essential to maintain a straight warp.
IN WARP THREADS

When the warp has been woven', out, a new beam is
placed in the loom and prepared for tying-in. The port-
able warp tying Machine is wheeled into position,
parallel with the beam. The new warp threads are
straightened by brushing, or with !!lease rods, and then
clamped into the lower warp frame. It is not necessary
to draw the old warp threads out of the harnesses, nor
to disturb the other weaving elements. The old warp
ends are prepared directly from the loom in the same
manner as the new warp, and are clamped into the
upper warp frame. In this manner the two sheets of
warp threads are held parallel about three inches
above the bed of the machine.
The mechanism for tying-in is contained in the carriage
which runs on guides along the bed of the machine.
The carriage is moved along the lbed until it contacts
the two warp sheets. The feed mechanism is engaged
and the machine operated by hand crank or motor. As
the threads are tied, the carriage feeds forward. If one
or both selectors fail to catch a thread, the knotter will
not function until a thread from each sheet is properly
picked. All functions are entirely automatic.
Precise selectors on the Type 15 LC pick only a single
thread each from the upper andi lower warp sheets.
These are fed to the knotter where they are tied to-
gether, and the ends trimmed off neatly. Warps may
be tied-in on Type 15 LC from a slasher comb, gummed
tape or lease rods. On Type 15 LS, special selectors are
used for selecting from an end-and-end Lease. The
Type 15 LL combines the selector features of both Types
15 LC and 15 LS.
The feeding mechanism is designed to automatically
take care of inequalities in the spacing of the threads.
Consequently, it does not have to be set when chang-
ing from different counts of yarn or sley.
Several interchangeable knotters are available for
handling different sizes of yarn.
Tying proceeds at the rate of 250 to 300 knots per
minute. In some cases these figures have been con-
siderably exceeded.
These machines are suitable for t Dying stripes, plaids or
multi-colored warps. A wide range of patterns and
yarns can be handled including: Ducks, Toweling,
Damasks, Crochet and Satin Quilts, Dobbies, Wide
Sheeting, Blankets, Corduroys and Multiple Beam
Work. Production should average 4000 to 9500 ends
per hour, depending on conditions and which model
machine is used.

WARP TYING MACHINES
? PROVIDE MOBILITY
? LIMITED SPACE CONVENIENCE
The views shown here demonstrate the flexibility and convenience of the Model L machine
for tying-in warp directly behind the loom. It is particularly adapted to close working quarters.
These machines are quickly and easily moved from loom to_ loom in alleys as narrow as 12
inches. Warp ends are tied-in quickly and uniformly, resulting in straight warps and mini-
mum warp replenishment.
The new figure-8 knotter mechanism on the carriage is capable of tying-in a much greater
range of yarns than ever before. These include fine crepe, combination novelty, nylon and
rayon yarns, with regular and reverse twist.
In the views showing tying-in of a wool warp, a Type 15 LS machine is used. This particular
machine is adapted to tying-in wool, worsted, mohair and other difficult yarns. These yarns
are easily tied using the figure-8 knotter. In these illustrations, warp threads are selected
from an end-and-end lease, providing perfectly straight warps. The view showing the wool
warp completely tied-in demonstrates important time and labor savings realized from tying-in
a new beam with the old warp, directly behind the loom. This eliminates an operation for
resetting weaving elements when a warp runs out.
Tying-in a variety of fine to coarse yarns is arranged on these models by simply changing
the knotter heads on the figure-8 mechanism. This change can be made by an experienced
operator in one or two minutes.
Further information will be furnished on request.

 warp to the ends of an old warp automatically,
irrespective of the kind and number of harnesses.
As will be seen from the illustration on the back
page of this circular, the machine consists of
(1) the selecting and tying mechanism which
travels on a lathe-like bed, (2) two beam trucks
which are pivoted and move on semi-circular
tracks, (3) a loader over which the yarn in the
set of harnesses is prepared for tying, and (4)
the overhead carrier which is fixed upon the wall.
The overhead carrier enables the old warp to be
easily moved from its position in the loader
to its position on the bed preparatory to tying.
Briefly, the method adopted is to so clamp the
old and the new warps as to hold them in two
parallel sheets, supported in planes one above
the other, the old warp being uppermost.
The carriage containing the tying mechanism
travels along the bed, picking consecutive threads
from each sheet of warp. These ends are then
tied together. The machine will not tie a knot
if a thread is missed by the selector, but after
five attempts to obtain the missing thread it will
stop automatically. When the knots are made
they are all uniform in size with ends closely
sheared, the shearings being mechanically ex-
pelled into a suitable receptacle at the end of
the carriage.
The object of having two beam trucks is to avoid
keeping the machine waiting between the finish-
ing of one warp and the beginning of the next,
so that while the machine is tying, the helper
can be preparing another beam in which-ever
truck is available. In this way the trucks are used
alternately and the time lost is reduced to a
minimum.
No mechanical alterations on the machine are
necessary when changing from one "style" to
another should the difference consist only in
the number of threads per inch, or in the number-
or kind of harnesses or banks of drop wires.
For a change in counts of yarn, the two selectors
may require changing, this operation being very
similar to changing two needles in a sewing
machine without the necessity of rethreading.
Ordinarily it is found advisable to use artificial-.-:.
humidity as would be necessary in weaving..:'.':- `:

WARP TYING MACHINE
MODEL "EL" STATIONARY
The post war period has shown that the trend is more toward fancy
patterns which necessitates a greater number of weaving elements in the
loom, that is, harness and banks of drop wires (automatic stop motion).
This change has presented a problem of choosing between our Sta-
tionary and Portable Warp Tying Machines so as to obtain the maximum
efficiency as well as a satisfactory return on your investment.
For weaves requiring over 6 harness and several banks of drop wires
we suggest that consideration be given to our Portable Warp Tying
Machines. To weave quality cloth extreme accuracy is required to
regait any number of harness. Obviously the greater the number of
harness required the greater the time in the regaiting process. Likewise
it is necessary to properly align a reed in order to weave quality cloth.
When the same reed remains in the loom for a long period of time it
does not become warped or twisted as in the case where the reed is con-
tinuously being changed. Consequently, when the Portable Warp
Tying Machine is used, there is less wear and tear on the reeds and
shuttles. The regaiting of the modern built steel heddles and frames
is a factor to consider in choosing between the Stationary and Portable
Warp Tying Machine.

The development of the Barber-Colman Automatic System has
practically eliminated the human element in spooling. The operator
of the spooler is required only to place bobbins in position to be
handled by the automatic mechanisms and to remove full packages.
Machines are not subject to such human characteristics as fatigue,
carelessness, indifference or the errors that are frequently found on
manually operated machinery. The operations performed by the
workers on these machines are extremely simple.
Work is of high quality, with only reasonable supervision required,
and such production is continuous, at great reduction in cost.

Only about half as many em-
ployees are required to handle
the same amount of yarn by the
Barber-Colman system as with systems depending on hand-
operated spoolers and winders. This reduction in the number
of employees required not only results in a decreased cost per
pound but releases labor which may be used to advantage in
other departments.
Thorough tests covering long periods of time
made in the weave rooms of several well-
known mills prove that yarn spooled and
warped on Barber-Colman machines weaves with less break-
age and with a higher percentage of production than yarn
spooled and warped on other systems.
In yarn mills or other mills where twisting
is done, better quality yarn produced by
the Barber-Colman system results in better
running twisters. Because of fewer ends down, labor is re-
duced and fewer twisters are required.
The use of Barber-Colman machinery
results in a large reduction of yarn in-
ventory in the spooling and warping
departments. The amount of yarn in process is reduced from
50% to 75%, as compared with the amount necessary when
using ordinary machinery.

Considerably less floor space is
required for the Barber-Colman
system than for the other systems.
In mills already built this released floor space can usually be
used to considerable advantage. In new mills, advantage can
always be taken of this saving in floor space to reduce initial
plant investment.
At no obligation to the mill and
using data obtained from the mill,
Barber-Colman Company will pre-
pare an estimate to show the equipment required and possible
return on investment from the installation of the Barber-
Colman system.
In most cases with the installation of Barber-Colman machinery,
a mill may expect a return of at least 25%, and some mills
have paid for their machines in one year.

The traveler on the Automatic Spooler can be set to
wind different size cheeses on each quarter of the
machine. Thus, four different counts or kinds of
yarn can be spooled on one machine at the same
time. Only a few minutes are required to change
counts and snick plate settings.
The number of ends on the Super-Speed Warper are
changed very easily, which makes it possible to
change patterns or get out short orders in much less
time than by other methods. The creel girl loads

The object of the spooling and warping process is
to combine numerous short threads into fewer long
ones, and then to assemble these long threads into
sheets. If this is not carefully done, the yarn may be
seriously injured, weakening it so that it will not
weave as well and the resultant cloth will be of poorer
quality. , The design and construction of Barber-Colman
machines keeps the yarn tension low and results in yarn
of more even quality than that wound by other systems.
5UPIEROO YARN CLEAMO NG In most cases it is desirable to
break out gouts, bad piece-ups, thick places and wild yarn,
which may later cause loom stoppage or defects in the cloth.
Barber-Colman Automatic Spoolers are equipped with auto-
matic cleaning devices, known as snick plates. These snick
plates remove foreign matter and imperfections without injury
to the yarn. Their efficiency is highly regarded where pro-
duction of quality yarn is required. Constant improvement in
the design of this unit has assured maximum efficiency in
removing undesirable matter.
LESS VALE'! fMt4CSp,G[ Loom beams from Barber-Colman
Warpers weave with less breakage than those from ordinary
beams. Low, uniform tension on the yarn provides equal
stretch to all strands and preserves elasticity for better strength
to stand the load at the loom. Less breakage at the Warper
results in better work at the slasher and straighter warps at
the loom.
High quality yarn, mechanically-tied weaver's knots, elimin-
ation of spooler kinks and removal of imperfections combine
to reduce loom stops and seconds in the cloth room.

NO DAMAGE V? YARN FROM a;IAMOLOMG To facilitate
handling the yarn from the Spooler to the Warper or Twister
without damage, a cheese carrier is used. This consists of a
base with three metal spindles, slightly less in diameter than
the inside of the sleeves or wooden cores on which the cheeses
are wound. This carrier is known as a "trident" and holds
fifteen cheeses.
The cheeses, handled on tridents, are much less liable to
injury than by other methods where spools may be thrown into
boxes or roughly handled, damaging the yarn.
LOW, UNIFORM YARN TENSION There is minimum tension on
yarn handled by the Barber-Colman system of spooling and
warping. On the Spooler no tension is applied to the running
thread except that which is caused in winding off from the
bobbin and from air friction.
No tension is applied to the yarn on the Super-Speed Warper
except that created as the yarn comes off the cheese overend.
Air is the only element that adds friction, and this provides
uniform tension equally to all running threads resulting in
superior beams. As a result of minimum uniform tension, the
strength and life of the yarn are fully preserved for the loom.
THE WEAVER'S CtNOVTER The-advantage of weaver's knots
and their importance in processes following spooling are gen-
erally recognized throughout the textile industry. More uniform
distribution of the mass of the knot around the yarn, less bulk
and decreased tendency to slip, allow the weaver's knot to
pass more readily through harness eyes and reed dents. The
result is fewer loom stops.
This type of knot also passes more freely though the eyes of
needles when the yarn is used in knitting machines. Knots
with short ends bury themselves more completely in cloth than
those having long ends. Long ends on knots frequently cause
many loom stops due to tangling with adjacent threads. This
is especially true on certain classes of work such as leno
weaves. The present weaver's knotter is standard equipment
on Automatic Spoolers. It ties knots with short ends, is entirely
mechanical and is not subject to the variations found in
hand-operated knotters.

Experience shows a great part of loom stoppage is due to kinks and subse-
quent warp breakage. On the Automatic Spooler, knots are tied and slack
controlled automatically, eliminating the factor of variable skill. This control
has reduced spooler kinks in actual installations by as much as 90%.
In studies under actual working conditions over a period of nine years, a
reduction of at least 25% in loom stops has been proved as a result of
installation of Barber-Colman Spooling and Warping. 92.2% of the re-
duction in these stops is due to automatic spooling, while 7.8% is attributed
to high speed warping. Weaving mills have reported increases in loom
efficiency ranging from 1.25% to as much as 12%. This improvement in
production is accounted for by elimination of spooler kinks, slack control,
low uniform yarn tension and subsequently less warp breakage.
Increase in loom efficiency and improved cloth means less inspection and
reduced seconds.

On the Barber-Colman Automatic Spooler the only work required of the operator
is to fill the bobbin holders, lay up the ends and replace the full cheeses. Cheeses
are placed on tridents carried by a small truck running on a track. The spooler
is equipped with a trident table the same height as the truck and having a series
of rollers on the top to make handling of tridents easier. Empty bobbins, or broken
down bobbins, are ejected by the machine to a conveyor which automatically de-
posits them on a sorting table at the end of the machine. The empty bobbins are
dropped into a bobbin truck conveniently placed at the end of the spooler and are
then ready to be transported back to the spinning room.
Doffing beams from a Barber-Colman Warper is simple with the beam doffing
mechanism that is included on the machine. It is so designed that an operator
can easily doff a full beam of yarn onto a beam truck without any lifting.

YARN MILLS An important application of Bar-
ber-Colman spooling is found in yarn mills. All
the advantages of yarn cleaning, reduced cost
and improved yarn quality produce substantial
savings in the spooling, twisting and balling
operations. Many yarn mills are taking advan-
tage of reduced spooling costs as offered by the
Barber-Colman system and are backwinding from
cheeses to sale cones.
CHEESE DYEING The cheese made on the Automatic Spooler has proven to be an excellent type
of package for dyeing purposes. Barber-Colman dye cheeses are being used with much success
in leading mills making toweling, fine shirting and broadcloth. Using direct, vat, napthol and
sulphur dyes, uniform penetration of the dye liquor is obtained making it possible to do excellent
work on pastel shades as well as dark colors.
The stainless steel dye sleeve is interchangeable with the standard "C" type bakelite sleeve used
on the Automatic Spooler and Super-Speed Warper. This makes it possible to run either the dye
sleeve or standard bakelite sleeve on the spooler and warper at the same time. The Barber-Colman
cheese is wound with hard sides and a soft center. This makes an ideal package for dyeing and
permits the dye liquor to flow radially through the cheese, insuring even penetration. Because
of the physical characteristics of the cheese, it is not necessary to backwind dyed cheeses before

placing them in the creel for warping. The Barber-Colman cheese can be taken direct from the
dye carrier and creeled in for striped or solid color beams. No special parts are required on the
Automatic Spooler for making the cheeses used for dyeing and only simple adjustments are
necessary in order to vary the density of the cheese.
DYE BEAM WARPING The Super-Speed Warper is exceptionally well adapted to winding dye
beams where low and uniform density of the yarn mass is required. Yarn wound on Barber-Colman
beams is dyed in the most difficult shades with complete satisfaction. Uniform density is one
single factor, which more than any other, determines the even flow and penetration of dye liquor.
This is provided on the Barber-Colman Warper because no mechanical tension is applied.
Air is the only element that adds friction and this provides tension equally to all running threads,
resulting in superior beams.
Another advantage of low uniform yam tension is the ability to wind beams soft enough for
satisfactory dye penetration at relatively high speeds. This is possible because no drag is applied
to the yarn and delivery is over the end of the cheese. Also, the action of the anti-bounder
device, which holds the beam firmly and with uniform pressure against the drum, permits winding
a beam of uniform density.
By driving the Warper with a two-speed motor, it is convenient to cut the speed in half by throwing
a switch. Section beams can thus be run at 900 yards per minute and dye beams at 450 yards
per minute. Best results are obtained with dye beams containing from 275 to 325 pounds of net yarn.

BALL WARPING All the advantages of the
Super-Speed Warper, such as low tension, flexi-
bility and high production, apply to ball warp-
ing, as the addition of a balling device with only
minor changes converts the Beam Warper to a
Ball Warper.
The winding speed of the Ball Warper is from
675 toy 750 yards per minute. The balls wound
are much larger than on ordinary ball warpers
and the increased yardage results in greater effi-
ciency in both beaming and slashing.
A special leasing comb has been devised whereby
the ends may be quickly and easily laid in, the
some as on our Beam Warper. By means of this comb, leases may be struck in about
30 seconds and, because of the improved character of the balls wound, only a frac-
tion of the number of leases required by other ballers is needed. As the ends are
broken out after every set of cheeses has been emptied, and the drop wires are easily
rendered inoperative, changes of yarn or number of ends may be made on each
successive ball without losing time.
It is entirely practical to run balls and beams on the same Warper, as it is not nec-
essary to remove the balling device when beams are wound, and the other changes
necessary can be easily made with but a minimum of lost time.

OF BARB ? ER-COINAM S'A'E
One well-known mill running chambray reports that after replacing warpers winding from cones
with Barber-Colman system ball warping, leases required per ball were reduced from 15 to 4.
At this same mill the time of beaming after dyeing was reduced 25% and tests showed loom stops
decreased approximately 34%.
In a large denim mill, the installation of the Barber-Colman System improved the character of
the balls run to the extent that leases were reduced from 7 to 4 per ball and beaming time
decreased about 28%.
A third mill, running a wide variety of work requiring ball warps, adopted Barber-Colman
machines and reduced leases per 10,000-yard ball from 10 to 3, and also experienced material
improvement in beaming.
SALE YARN BALLING To meet the needs of mills who ship yarn in ball form, a special Warper
has been developed. This machine retains the advantages of other Barber-Colman Warpers,
such as low tension, flexibility and high production. It is equipped with the same over-end creel
and leasing mechanism as the Super-Speed Ball Warper which has already been described,
and the winding speed may be as high as 450 yards per minute depending on specific mill
conditions. The maximum sale ball contains approximately 400 pounds of yarn.
Ordinarily when this Warper is installed it is not necessary to make changes in either the type
of ball or log in use. For mills that require both sale balls and regular section beams, a combi-
nation section beam and shaftless baller can be furnished such as shown.

TVP12 CC CHEESES Where a great amount of twisting is to be done, the type CC Spooler is
recommended. To convert a mill's present creels to accommodate Barber-Colman type CC
cheeses, it is necessary in most cases only to replace the spindles. This keeps the cost of
conversion to a minimum. In cases where replacement is not practical, Barber-Colman
creels with spindles properly spaced may be supplied to fit the mill's twisters.
Using twister creel skewers designed for type CC cheeses, it is possible to twist coarse and
medium fine counts on the offset spindle. Creeling is simple, easy and rapid when using the
inexpensive type CC spindle.
7VPL C [BALD LMG,IR9MG SPOMD12 When twisting finer yarns from cheeses, ends down are
kept at a minimum by mounting the cheeses on skewers equipped with ball bearings. With
this type of bearing, friction is extremely low and it is necessary to add some sort of drag to
insure uniform tension and prevent over-running when stopping. This drag is applied to the
surface of the cheese through a hinged metal strip or paddle, the weight of which can be
varied. Tension thus can be kept low and equal on each running end.
To facilitate creeling, the spindles on the type C ball-bearing twister creel are hinged so
they may be turned at right angles to their running position. The skewer is held on the spindle
at all times. The sleeve holding the yarn is slipped over the skewer and held in place by a
detent which engages the groove inside the sleeve.

TYPE C PLAIN SPINDLE With this type it is neces-
sary to use some sort of "adapter" or "skewer" for
holding the cheese on the creel spindle. A bakelite
skewer has been developed for this purpose. No
drag is required, the friction of the bakelite skewer
on the spindle being sufficient to prevent slack in
the yarn and over-running when stopping. The low
and uniform tension results in satisfactory twist
being obtained with a minimum number of ends
down during twisting.
BEAM TWISTING The Barber-Colman Super-Speed
Warper winds beams with a minimum of crossed
ends, in perfect balance and with smooth round
surfaces which permit the most satisfactory twisting.
Mills have found Barber-Colman beams satisfactory
as a yarn supply for twisting fine yarn numbers.
Tire yarns are usually twisted from beams and a
large percentage of the mills on this type of work
can testify to the superiority of Barber-Colman beams
for this purpose.

1. Improved Product Quality
2. Increased Production through less stops
for cleaning.
3. Improved working conditions provide greater
production per worker.
4. Less Sweeping Required.
The illustration above shows in detail the parts of the
Suction Cleaning System which are attached to the
Spooler. Practically all of the lint at the Spooler is
formed in the bobbin pockets as the yarn unwinds.
Manifolds containing vertical slots are located directly
behind and close to the bobbins to collect the lint at its
source before it has an opportunity to get out into the
room. By collecting the lint at its source, the minimum
amount of air is moved to collect the maximum amount
of lint and as a result a minimum amount of horse-
power is, required. The trough under the bobbin pockets
collects the heavier material such as leaf. As the trav-
eler moves around the Spooler, the air from the traveler
fan pushes this heavier material to the openings in the
trough where it is sucked into the collector pipe. The
center guards are designed to take advantage of the
air currents set up by the drums. These currents are
directed toward the suction slots in the manifolds.
LAYOUT - Drawings show a typical layout for the
Fan and Lint Collector, used with the Suction Cleaning
System on the Spooler. By hanging the fan from the
ceiling below, a minimum amount of floor space is
used, and only three holes have to be cut in the floor -
two for the pipes leading from the collector pipes on
the Spooler, and one for the delivery pipe to the lint
collector. It is also possible to mount the fan on the
ceiling above the Spooler and run the collector pipes
up to it, thus avoiding cutting any holes in the floor.
AIR FLOW - In the drawing, arrows show the direction
of air currents which pick up lint at points of formation
and carry it toward the suction slots in the manifold
back of the bobbin pockets. The blast nozzles shown
at the left are carried on the traveler and act as addi-
tional scavengers of any loose material which may
have caught on the machine. The center guards which
direct the currents set up by the drums, the trough
below the bobbin pockets for heavier material such
as leaf, the suction manifold and the two collector
pipes, are all clearly shown by heavy lines.

 OPERATION OF THE
Type CC Cheese, Core and Live
Spindle
The Barber-Colman Automatic Spooler is made in
two different types, the C and CC. The type C
Spooler was the first of the two developed and it
winds a package of about 2-1/2 pounds on a Bake-
lite sleeve. Later the type CC Spooler was developed,
primarily for use in mills where supply packages
for twister creels were needed, and this type Spooler
uses a wooden core. A full cheese from a type CC
Spooler is slightly heavier than a type C cheese.
The Automatic Spooler winds a yarn package known
as a cheese. The yarn is wound crisscross, making
it possible to build up a self-sustaining yarn mass.
On the type C Spooler a headless bakelite sleeve is
used to make the cheese. This sleeve slips over a
ball bearing core, retained as an integral part of
the Spooler. A groove inside the sleeve and a ball
detent on the core hold the two in rigid alignment.
The type CC Spooler uses a wooden core on which
to build the cheese. This wooden core slips over live
spindles, retained as integral parts of the Spooler.
Rigid alignment between core and spindle is held
through a similar ball detent and groove arrangement.
The following description of the Automatic Spooler
applies to either the type C or CC. The Automatic
Spooler consists of a long frame with a series of
spindles or winding units mounted on each side of it.
Each winding unit has a swinging arm which sup-
ports a cheese upon a spindle with its axis horizontal.
By means of this arm the cheese is swung into
contact with a drum having a zigzag groove
which guides the thread onto the surface of the
cheese. Below the unit is the bobbin holder on
the top of which is the snick plate (yarn cleaner).
The bobbin from which the yarn is wound is mounted

on a skewer in such a manner that the yarn is drawn off the end of the
bobbin. The usual winding speed is 1200 yards per minute.
A traveling mechanism known as the traveler is mounted on top of the
frame. This traveler is driven by an electric motor and is timed to make
a complete circuit of the machine after each set of bobbins has been
run off. As the traveler starts down the side of the machine it finds the end
on the surface of the cheese by means of suction and carries this end down
to the knotter. There the bobbin end, which has already been picked up
by the forward movement of the traveler, is waiting. The two ends are
tied together and as the knot is cast off the slack is taken up by suction.
This action prevents the kinks which are so common in hand spooling or
winding and which cause a large proportion of stops in the loom. The
cheese is then swung over into contact with the revolving drum and the
thread dropped into the zigzag groove. The winding begins immediately
upon contact of the cheese with the drum. While the knot is being tied,
the empty bobbin is ejected from the bobbin holder. As the cheese goes
over to the drum, the bobbin just tied to it is swung from the reserve holder
into running position.
The traveler moves along the machine and the thread detector swings
into contact with the running thread. The function of this detector is to
cause the removal of the cheese from contact with the drum, whenever the
cheese becomes full or when a thread breaks or runs out.
All cheeses are measured as the traveler passes. Full cheeses are not
tied up. The bobbins remaining in the reserve holders are a signal to the
operator that the cheese should be removed and a starter put in its place.
A starter is a sleeve or core having a few layers of yarn.

Empty bobbins and partially filled bobbins which
have broken down during running are ejected from
the holder to a conveyor. This deposits them on a
sorting table at one end of the machine. The op-
erator, each time around, sorts out those having
yarn left and places them back in the bobbin
holders to be tied again. The empty bobbins are
dropped into trucks beneath the table. Those badly
tangled, or with too small an amount of yarn to be
economically handled on the Spooler, are sent to
a smaller winding machine called a Tailings Ma-
chine where they are straightened up or cleaned off.
The same series of operations is performed on each
cheese all around the machine. As soon as the
traveler has passed the first winding unit, an oper-
ator follows it filling the reserve holders with fresh
bobbins, as shown. She places the end of yarn from
each bobbin in a thread clamp in a position to be
engaged by the knotter as it passes along the frame.
She replaces all full cheeses with starters as shown.
The full cheeses are placed on tridents carried on
a small truck which runs on a track and is pushed
ahead of her along the machine.

transfers it to a trident table at the end of the Spooler.
The Spooler may be equipped with either one or two
trident tables, depending on whether the delivery
of empty bobbins is made to one or both ends. The
trident table, the top of which is a series of rollers to
make the handling of tridents easier, holds full and
empty tridents as they are taken to the Warper and

A Super-Speed Warper is shown running striped beams. The creel is made up of a
series of vertical bars, each carrying nine cheese holders or spindles. These holders
are built with a spring detent which engages the groove inside the bakelite sleeve
and fixes the cheese firmly in position. When these Warpers are used on coarse yarns,
the holders are placed in cheese containers or receptacles which prevent ballooning
together of the running threads. The upper and lower ends of the vertical bars which
carry the cheese holders are connected to endless sprocket chains running length-
wise of the creel. These chains extend along the outside of the creel around sprockets
at both ends of each creel section and back on the inside, carrying a continuous
series of cheese holders on both the outside and inside of each section. This permits
the creeling of cheeses on the inside of the creel while the Warper is in operation.
The cheeses are held stationary and the yarn pulled off over the end. When the
yarn has been wound off the cheeses on the outside of the creel, a small motor is
started and the "starters" or nearly empty sleeves are moved to the inside of the creel.

This same movement brings the full cheeses from the inside of the creel to running
position on the outside. The ends which have been picked up from each vertical
row of cheeses at the time of creeling and left hanging as a loose cord, are now in
position to be carried forward to the Warper and laid into the single comb. The ends
are usually brought forward several rows at a time by a creel girl and passed to the
warper tender who, standing in front of the
Warper, lays them into a special comb designed
for laying-in the ends quickly without error. The
whole operation of turning the creel, changing
the beam and laying the ends in the comb con-
sumes a total average time of less than fifteen
minutes. The fact that the ends are broken out
after every set of beams, and that individual drop
wires are so arranged that they may be quickly
and easily rendered inoperative, makes this type
of Warper the most flexible Warping Machine
ever offered to the textile industry. Changes of
yarn or number of ends may be made on each
successive beam without loss of time.

The breaking of a thread permits the drop wire to fall from the running position
making an electrical connection inside the bar holding the drop wires (where it is
impossible for lint to accumulate and prevent action). Completion of the circuit
through a solenoid releases a spring cluster which actuates a brake, stopping the
rotation of the beam in time to avoid burying the broken end. At the same time
all of the drop wires assume the position shown. This places sufficient tension on each
strand of yarn to pull out any kinks that may form due to the overrun of the yarn.
This tension remains on the yarn during the operation of the Warper at low speed,
but is removed as the Warper reaches high speed.

The careful avoidance of both kinks and high tension during the spooling must be
continued through the warping if worthwhile improvement is to be shown in sub-
sequent processes. The winding speed of this Warper is 900 yards per minute.
In spite of the high speed the tension is low and uniform due to the fact that no
drag is applied to the running threads. Air friction alone supplies the necessary
tautness to assure the winding of a smooth beam. The effect of this low and uniform
tension, a fraction of that found on other warpers, is the production of a beam in
which all the ends are stressed alike. This assures weaving with less breakage
than is normal for beams wound with high and unequal tension.
