finished being (50 to 72)/x where x is the total number of threads
required for the cloth. The same kind of lease must again be made on
the same two pins at the bottom for the beginning of the next
section of 50 to 72 threads, and the mill rotated in the opposite
direction in order to draw up the heck, and to cause the second
group of 50 to 72 threads to be arranged spirally and in close touch
with the threads of the first group. When the heck reaches the top of
the mill, the single-thread lease is again made, all the threads
passed round the end pin, and then all is ready for repeating the
same two operations until the requisite number of threads has been
introduced on to the mill. If it is impossible to accommodate all the
threads for the cloth on the mill, the warp is made in two or more
parts or chains. It will be noticed that the heck for the nearest
mill is opposite about the 12th round of threads from the bobbin,
whereas the heck for the second mill is about the same distance from
the top. A completed warp or chain is being bundled up opposite the
third mill. When the warp is completed it is pulled off the mill and
simultaneously linked into a chain.
A very similar kind of warp can be made more quickly, and often
better, on what is termed the linking machine mentioned in No. 2
method. Such a machine is illustrated in Fig. 28, and the full
equipment demands the following four distinct kinds of apparatus--a
bank capable of holding approximately 300 spools, a frame for
forming the weaver's lease and the beamer's lease, machine for
drawing the threads from the spools in the bank and for measuring
the length and marking the warp at predetermined intervals, and
finally the actual machine which links the group of threads in the
form of a chain.
In Fig. 28 part of the large bank, with a few rows of spools, is
shown in the extreme background. The two sets of threads, from the
two wings of the bank, are seen distinctly, and the machine or frame
immediately in front of the bank is where the two kinds of lease are
made when desired, i.e. at the beginning and at the end of the warp.
Between this leasing frame and the linking machine proper, shown in
the foreground, is the drawing, measuring and marking machine. Only
part of this machine is seen--the driving pulleys and part of the
frame adjoining them. All these frames and machines are necessary,
but the movements embodied in them, or the functions which they
perform,
