ix times the length; six of these ribbons similarly treated and formed into one; six of the latter by a third operation, formed into one sliver; and five of these drawn into one, — will have the effect of placing the fibers parallel to each other 1080 times (6 × 6 × 6 × 5=1080). The drawing-frame for long-stapled wool is for drawing out and extending the slivers which have already been operated upon by the breaking-frame (which see). This is a repetitive operation, and it is usual to pass th1080). The drawing-frame for long-stapled wool is for drawing out and extending the slivers which have already been operated upon by the breaking-frame (which see). This is a repetitive operation, and it is usual to pass the wool through the breaking-frame and four times through the drawing-frame before roving. These slivers are united at each drawing, and are extended to, say, four times the length. The result is an actual extension and an oft-repeated laying of the slivers alongside of each other, so as to blend them and reduce inequalities. 2. (Silk-machinery.) A machine in which the fibers of floss or refuse silk are laid parallel, preparatory to being cut into lengths by the cutting-engine, to be afterw
