The jute industry : $b from seed to finished cloth
Woodhouse, Thomas
Jute fiber
The completed chain from the warping mill or the linking machine is
now taken to the beaming frame, and after the threads, or rather the
small groups of threads, in the pin lease have been disposed in a
kind of coarse comb or reed, termed an veneer or radial, and
arranged to occupy the desired width in the veneer, they are
attached in some suitable way to the weaver's beam. The chain is
held taut, and weights applied to the presser on the beam while the
latter is rotated. In this way a solid compact beam of yarn is
obtained. The end of the warp--that one that goes on to the beam
last--contains the weaver's lease, and when the completed beam is
removed from the beaming or winding-on frame, this single-thread
lease enables the next operative to select the threads individually
and to draw the threads, usually single, but sometimes in pairs, in
which case the lease would be in pairs, through the eyes of the
camas or HEALDS, or to select them for the purpose of tying them to
the ends of the warp in the loom, that is to the "thrum" of a cloth
which has been completed.
Instead of first making a warp or chain on the warping mill, or on
the linking machine, and then beaming such warp on to the weaver's
beam or loom beam as already described, two otherwise distinct
processes of warping and beaming may be conducted simultaneously.
Thus, the total number of threads required for the manufacture of any
particular kind of cloth--unless the number of threads happens to be
very high--may be wound on to the loom beam direct from the spools.
Say, for example, a warp was required to be 600 yards long, and that
there should be 500 threads in all. Five hundred spools of warp yarn
would be placed in the two wings of a V-shaped bank, and the threads
from these spools taken in regular order, and threaded through the
splits or openings of a reed which is placed in a suitable position
in regard to the winding-on mechanism. Some of the machines which
perform the winding-on of the yarn are comparatively simple, while
others are more or less complicated. In some the loom beam rotates
at a fixed number of revolutions per minute, while in others the
beam rotates at a gradually decreasing number of revolutions per
minute. One of the latter types made by MESSRS Urquhart, Lindsay & Co.,
Ltd., Dundee, is illustrated in Fig. 29, and the mechanism displayed
is identical with that employed for No. 4 method of preparing warps.
