The width of the coloured border is generally about 1 inch, although
extending to 4 inches in special cases.
The beams are warped in the manner described for plain dhooties, but
only the grey ends are drawn in the healds with any coloured warp
which has to weave plain. The ends which form the pattern are drawn
through harness composed of separate leashes and mail eyes, each with
an elastic thread tied to them. These we will refer to as the leashes.
They are placed behind the healds and tied as required to the jacks
above; the elastic cords are fixed to a bracket below, so as to draw
down the leash after the shedding. Above the mail eye is fixed a cumber
board perforated with rows of small holes, and used for keeping the
leashes in proper order, so as not to become entangled in the weaving.
A clear pattern is a great desideratum in this cloth, consequently it
is generally woven face down to prevent spoiling face by drooping ends.
In pegging for it the wrong side of the cloth is taken, a pattern of
it obtained from the coloured figuring ends only in the usual way, and
drafted on the required number of jacks. The leashes are drawn through
the cumber board about 6 in each row, but so arranged as to have all
those to be tied to one jack drafted together.
The ends are drawn through at the drawer-in’s frame, and the leashes
having been previously looped in bunches, each bunch containing those
intended for one jack, the beam is ready for the loom.
In gaiting up, the coloured ends often pass over a small special back
rest, and the bunches of leashes are tied to their respective jacks.
By pegging the dobby in the required order any desired jack or jacks
may be raised, and those ends kept above the plain cloth. When the
jacks are lowered back the same ends will weave below the plain cloth.
The body of the cloth is generally of plain weave, although stripe and
check patterns are occasionally introduced.

GAUZE AND LENO CLOTH.
This class of fabric is frequently woven by means of the dobby,
although the tappet and jacquard are occasionally used should the
pattern come within the scope of either. The peculiarity of gauze
is, that some of the warp ends cross over one or more of the other
warp ends between the picks, giving an open fabric, sometimes of a
beautifully delicate nature, and yet strong, considering the small
amount of material used. When gauze weaving is combined with plain it
is styled leno. The latter name is sometimes erroneously attached to
the gauze itself.
[Illustration: FIG. 54.]
Fig. 53 shows a pure gauze in plan, and Fig. 54 the same in section.
[Illustration: FIG. 55.]
Fig. 55 is the plan of a leno. The threads marked heavily in each
case are the crossing threads. It will be noted from Fig. 54 that the
crossing thread passes up alternately at each side of the backing
thread, pick by pick.
