The succeeding operations of draxcing and doubling areperformed in machines greatly resembling those used in flaxspinning, as a glimpse at the jute chain gilling machine inFig. 172, and the jute worm gilling machine in Fig, 173 willreadily show. All that is, therefore, necessary is to drawattention to the slight differences between them. In the firstplace, the ratch is only about 12 inches; next, the pressureroller, /, instead of being bare, is shod with leather; and inthe chain machine a pair of guide rollers, vi, n, are provided.

The manner in which the sliver is?delivered from a four-head jute drawing frame is illustrated indetail by Fig. 174, which shows the plate, h, the lower deliveryrollers, k, and the cans, /, viewed from above. Roving in the jute roving frame is carried on in the samemanner as for flax, the machinery being very similar in bothcases. This will be evident from a glance at the verticalsection of a jute roving frame shown in Fig. 175, the soledifferences being the shorter ratch and the consequent reduc- TEXTILE RAW MATERIALS. 285 tion in the number of gill , as also the leather coveringprovided for the pre
