Summary
[edit]DescriptionEB1911 Wool, Worsted and Woollen Manufactures - Section of Wool Drawing Rollers.jpg |
English: Section of Wool Drawing Rollers. A, A′ are the back-rollers in a drawing box of which A is positively driven and A′ driven by friction which may be varied at will. Carriers B, B′, B″ simply control the fibres of which the sliver is composed during drafting. The front rollers C, C′—of which C is positively driven and C′ driven by friction—running at a greater speed than A, A′ draft or elongate the slivers as required. The carriers B, B′, B″ should be speeded to run at a suitable rate to assist the drafting operation, more by support than by direct aid. Rollers A, A′ must hold the sliver, hence they are fluted. Rollers C, C′ must pull the sliver somewhat severely, hence roller C′ is covered with leather. The yarn delivered by the front rollers is slightly twisted and wound into a double-headed bobbin of convenient size on the “flyer-system.” |
