These form the simplest and most common method of drawing-in. We begin with

the first heddle on the left side of the shaft _nearest to the warp-beam_,

then take the first heddle of second shaft and so on until all the shafts

the set contains are used in rotation. This completes one "draw," and this

operation is repeated until all the warp-threads are taken up.

The method of making the shaft nearest to the warp-beam the first, is

almost universal with the silk business and is technically called

_drawing-in from back to front_.

The opposite, or drawing in from _front to rear_, is used occasionally,

however, and in this case makes the first heddle on the left hand side of

the front shaft No. 1.

The making out of the _Drawing-in Draft_, which must indicate the

arrangement or the rotation in which the warp-threads are drawn in, can be

done in various ways, of which we will mention the two most popular

methods. The first is by using common designing paper, and indicating the

rotation by dots. The horizonal rows of squares represent the shafts, the

vertical rows the warp-threads. Fig. 1 shows four repeats of a straight

draw on six harness marked out according to this idea. A second method is

to use paper ruled horizontally, the lines representing the shafts; and to

draw vertical lines for the warp-threads. The latter are made to stop on

[Page 9]

the lines bearing the number of the shafts into which the respective

threads are to be drawn. Fig. 2 is such a draft, illustrating six repeats

of a draw on four harness from "Front to Rear."
