The round edge or covering for the outside rubber threads is drawn in the harness on the upper shed, and while being woven this cloth is pulled around the rubbers by the tension of the filling which is carried in the lower shuttle. This tension is greater than that carried in the upper shuttle, and so asserts itself by pulling the edge cloth around the outside rubber until it meets the back cloth weave. The upper and lower fillings are connected by what are known as tie threads. These threads are drawn in the harness at each side of the body warp, next to the edge, and are part of the binder warp. They are operated from the binder harness, but are only allowed to travel through the lower shed as far as the center of the web, instead of going all through both sheds, as do the balance of the binder warp. This movement is accomplished by the use of long looped harness eyes, which only carry these particular threads through the one shed. [Illustration: Fig. 1.—Effective Combination of Weaves In a Fine Web] [Illustration: Figs. 2 and 3.—Sunken Effects] [Illustration: Fig. 1A.—Harness and Chain Draft for Fig. 1] [Illustration: Fig. 4.—Position of Rolls in Relation to Breast Beam for Cross Shot Weaving] The binder movement, extending through the two sheds, is formed by a longer sweep from extra throw cams, or by the use of extended cam jacks, or by a combination of both. The balance of these goods may be regulated both by the warp and the filling, and any tendency towards curling may be corrected by changing the weight of stock used on either. USE OF DIFFERENT STOCKS AND COLORS The use of upper and lower fillings also allows for the use of different grades of stock in either shuttle. Colors may be used to match the face warps while white may be carried in the lower shuttle to match the back. Silk or other expensive stock may be used for the face without changing the character of the stock used for the back of the goods, which is not practicable in single shuttle work. All this of course makes it possible to reduce the cost, making this the most economical web produced. In the making of shoe goring, a considerable quantity of which is still used for inserts for house slippers, this is a very popular form of weaving, allowing for the production of a face having a velvet-like pile of the color to match the shoe leather, while the back may be perfectly plain and white. It is a method employed in combination with the jacquard, where fancy figures may be obtained on the face, using the cam movement for the back, binder and edge, the weave of which is the same for all of these warps, being simply a one up and one down. In such a combination the labor on the jacquard movement is much reduced, inasmuch as the travel of the lingo is much shorter than is required when made in connection with single shuttle.
