Abstract
Disclosed herein is a fiber feeding roller for an open-end spinning apparatus, wherein a plurality of projections with flat surface are formed in rows extending in axial direction of the body of said fiber feeding roller on the outer circumferential surface thereof and, simultaneously, a plurality of projections with knurled surface are arranged between the aforesaid projections with flat surface, whereby preventing harmful sliver slippage on said feeding roller and also providing a uniform nip for the sliver irrespective of the size thereof so that said fiber feeding roller may be applicable to a wider range of count numbers of spinning yarns and the quality of such spinned yarns may be improved as well.
