This division of drawing-in drafts is used extensively in silk manufacturing; for instance, in all fabrics having a ground warp and a binder warp, also in double-face goods, or where two different weaves are combined in one effect.
One or more threads are drawn on the first section, then one or more on a second and third, if the harness is divided in so many sets.
The following examples will illustrate the principle of these draws.
In Fig. [10], shafts 1, 2, 3, 4 from the first set, shafts 5 and 6 the second, 8 threads are drawn straight on the first, then 2 on the second section.
Fig. [11], first set shafts 1 to 6 inclusive, second set shafts 7 and 8.
Fig. [12] is drawn end and end on two sections having 8 shafts each.
Figs. [13], [14] and [15], while not strictly belonging to the class of section draws, may, however, be considered under this heading. The idea is to draw a certain number of ends in one part of the harness and another group in another part, be it straight, point or skip, which will cause the effect on the cloth to be accordingly transposed or broken up.
