Vertical feeding system is used in DREFII, DREF-III and DREF-2000 friction spinning machines. The inclined fibre feeding system is used in the PSL Masterspinner and DREF-5 spinning machine. Multiple slivers are fed vertically in the DREF-II and DREF-III friction spinning system. This method has been found to be suitable only for production of coarser yarns. According to studies, feeding the fibre stream at an oblique angle onto the drum is the best solution for production of __________ yarns.
