FIG. 36.

FIG. 37.

Figs. [36] and [37] show the design and cording plan respectively for a twill cloth requiring eight treadles.

FIG. 38.

The hand loom is practically obsolete in the cotton trade, but it is still extensively used in silk manufacture, where power looms, as at present constructed, are not found advantageous for weaving the finer classes of goods.

The chief shedding motions in power looms are tappets, dobbies, and jacquards.

There are various kinds of tappets, the simplest and best for plain or twill weaving being those shown at Figs. [38] and [39]. The former is the more general arrangement. In this the tappets are placed under the loom, inside the framework. In the arrangement shown at [Fig. 39] the tappets are placed outside the loom, and thus a larger amount of floor space is taken up by the latter than the former.
