. The principles and processes of cotton yarn manufacture. aced behind the frame, andeach sliver is fed separately into the machine; there is no doubling. Theslivers pass over a tin or wooden carrying roll shown, thence throughguide holes in a strip of wood extending the whole length of the frame,and then they come within the action of three sets of draAving rollers. Allthe draft is introduced by these rollers on exactly the same principle aspreviously described. The rollers resemble closely drawing-frame bottom ones are of steel made in short lengths and coupled togetherin the manner previously described. Their bosses are fluted longitudin-ally, but the pitch of the flutes is less and the bosses shorter than on a 10 136 COTTON YARN MANU]?ACTURE; drawing frame. A front view of a portion of the drawing rolls of a slub-ber is shown in Fig. 94. These bosses can be seen at b; there are usuallyfour between roller stands on a slubber. The roller stands which supportthe bottom rollers can well be understood from Fig. 95. The necks of the. rolls rest in the steps I. The stand G is bolted to the frame of the machineand has attached to it the movable stands F and H, which support themiddle and back rolls, respectively. By loosening the nut g the standsF and H can be moved forward or backward, thus regulating the distancebetween the different sets of rolls. B is a wooden cleared, to the bottom J J J J}
