In drafting apparatus of the kind comprising successive intake, intermediate and delivery drafting roller lines each incorporating driving and driven rollers, the driven rollers are transversely mounted on parts of a carrier member influenced by elastic means and located lengthwise of the drafting path between driving rollers positioned below and above the drafting path, so that the intake and delivery driven rollers are urged in one direction towards their co-operating driving rollers disposed on one side of the path while at least one intermediate driven roller is oppositely urged towards at least one intermediate driving roller disposed on the other side of the path. In the forms shown, the driving rollers 1, 2, 3 are formed as fluted bosses on long cylinders supported in stands at intervals in the frame, the intake and delivery driving rollers 1, 3 being below, and the intermediate driving roller 2 being above, the drafting path. There are two pairs of intermediate driven rollers, each pair supporting an apron 17, 19. These rollers and the driven intake roller are supported by a rear part of a carrier member, and the driven delivery roller by a front part of a carrier member, each part being formed by side plates joined at the ends. In Fig. 2, the side plates of part 6 each have an open-ended slot 28 and are interconnected by a cross-piece 27, a pin 26 and a handle-member 24. The side plates of part 7 each have an open ended slot 8d, slots 16 for the arbors of the upper driven intermediate rollers 14, 15, and a headed pin 30, and are interconnected by a spring-clip 11, and a sliver-guide 9. The arbors 14a of the forward upper intermediate driven roller 14 extend through slots 16 into the slots 28 to join the parts 6, 7. A spring 29 embraces the pins 26, 30 and tends to raise the joint so that the rollers 4, 5 are urged downwardly on to their companion driving rollers and the rollers 14, 15 are urged upwardly against driving roller 2. The part 6 can be raised about the pivot 14a into a stable position, the spring 29 moving over a dead centre and pin 26 coming to rest on projections 8f on part 7. By then removing clip 12 and lifting spring 29 off the pins 30, the front part 6 can be withdrawn and the side plates of part 7 separated to give access to the parts between them. In Fig. 4, the driven rollers are of the dual boss type supported and weighted from their centre arbors. The carrier parts 37, 38 have downwardly-opening slots fitting over the arbors of the driven rollers 31, 32, and upwardlyopening slots receiving the arbors of driven aproncarrying rollers 33.. 36. The side plates of part 37 are pivoted on a pin 39 arranged between the plates of part 38 and a torsion-spring 40 surrounds the pin with its free ends bearing against pins 42, 41 . fixed in the parts 37, 38 respectively. The spring tends to urge part 37 downwardly and raise joint 39 so that the driven rollers are urged into engagement with their corresponding driving rollers. The plates of part 37 are interconnected by a handle 37a and those of part 38 carry a bar 49 with sliver guides 50. When part 37 is raised by handle 37a, a pivoted catch engages a pin 53 secured to part 38 to relieve the weighting pressure: if it is then desired to retain the load on the remaining driven rollers when roller 32 is removed, the part 37 can be lowered by releasing the catch until it rests on the roller 3. In both forms, the position of the carrier parts is maintained in the direction of the fibre path by the engagement of the fixed roller 2 with the upper intermediate driven rollers; in Fig. 2, displacement of the carrier in a direction at right angles to the sliver path is prevented by the engagement of projections 8e with the flanges of the boss of the intermediate driving roller, and in Fig. 4, by the provision of bosses on the centre arbor of driven rollers between the side plates of the part 37. Longitudinal movement can alternatively be prevented by using two intermediate driving rollers above the fibre path with a single intermediate driven roller pressed upwardly between them. The springs may be replaced by coverings of soft rubber etc. on the driven rollers, the geometry of the arrangement then ensuring that the driven rollers are urged into engagement with the driving rollers.
