Each segment-roller consists of an axle with four segments, best shown in Figs. 22 and 23. The outer shell of the segments is made of hard wood, fitting an inner shell of malleable cast-iron, the projections on which suit grooves on the cast-iron axle. The segments of the rollers _c d_ are moved laterally to and fro by the wedge-shaped cams _p q r s_, fixed to the bearings of the roller-axles; and the segments of the roller _e_ are moved in the same manner by cams _t u_, fixed to the swing-frame _f_. The tobacco occupies the central space between the 3 rollers, and the cams _p r t_ move the segments in the direction of the arrow where they touch the tobacco, while the cams _q s u_ move them back. After the tobacco has passed beyond the segment-rollers, it goes through the hollow trunnion of the open frame _g_, in which the bobbin _h_ revolves; the other trunnion of the frame _g_ is provided with fast and loose pulleys, by which the whole machine is driven. To this trunnion, are also fixed an ordinary friction-break pulley, and a grooved pulley, around which latter passes a band for driving the pulley on the axle of the bobbin _h_. To the other end of the axle of the bobbin, is fixed a pinion, which, by means of a toothed chain, gives motion to another pinion fixed to the double screw _i_; this double screw gives a traversing to-and-fro motion to the guide _j_, for distributing the tobacco evenly on the bobbin, by means of a swivel =Ｔ=-headed stud, connected with the guide, and taking into the thread of the double screw. The guide is provided with two horizontal grooved rollers, between which the tobacco passes, and with two other rollers to guide the tobacco on to the bobbin.
