WINDING FROM THE HANK.
Coloured yarn used for dhootie and other striped cloth is received by
the manufacturer in the hank, in which form it is dyed. When winding
it on the ordinary bobbin for warp, only slight modifications of the
winding frame are required. A swift is substituted for the spindle
rail, and used for holding the hanks while unwinding them, while the
kneeboard and brushes are absent. If the coloured yarn be used for weft
for heading purposes, a pirn is substituted for the bobbin.
Other systems of winding have been introduced with only partial
success, the principal one being a modification of drum-winding: a tube
on which the yarn is wound rests horizontally on a revolving drum, the
thread traverses the width of the drum, and thus a bobbin is built up,
having level edges sufficiently firm without any protecting flanges.
The ordinary drum-winding is similar, excepting that a flanged bobbin
is used.
BEAM-WARPING.
Three methods of warping are in use, but far ahead of the others in
production stands the beaming system. To enable a sufficient number of
threads to be gathered in one sheet for sizing purposes, say 2000, it
is necessary to wind them first on a warper’s beam. This is a round
roller, of wood, five inches in diameter, having an iron flange 20
inches diameter, and also an iron pivot at each end. This will hold 500
ends, each 15,000 to 20,000 yards in length, so that for a cloth of
2000 ends four beams are required at the sizing machine.
The beam-warping machine is for the purpose of warping the yarn from
these 500 bobbins to a beam.
The bobbins from the winding frame are placed in a creel, generally a
[V] creel, and shaped in plan view as its name indicates, each arm of
the [V] being a frame containing tiers of pegs to hold 250 bobbins, the
apex being nearest to the frame. The yarn passes through a reed, under
and over several horizontal rollers, emerging in front through a guide
comb, and thence to the beam. The beam is driven by friction, resting
on a large drum making about 50 revolutions per minute; therefore,
whatever the size of the beam may be--_i.e._, whether full or
empty--the yarn, being pulled at the front, is travelling at a constant
speed.
To avoid sudden strains of yarn the creel does not rest on the floor,
but is suspended from overhead beams by rods. The older makes of
beaming frames have a bed creel. Only one vertical creel is used, the
other half of the bobbins being fixed in a horizontal frame. The [V]
creel is preferable.
The whole frame occupies a space of about 16 by 18 feet.
