摘要： A method of and apparatus for frictional open-end spinning which is an improvement upon that disclosed by the co-assigned U.S. Pat. No. 4,168,601. Continuously supplied separated fibers are deposited onto a first, frictional carrying surface provided on a revolving carrier and designed for conveying the fibers to the mouth of a wedge-like gap defined by said frictional carrying surface and a second frictional surface provided on a second revolving carrier moving in said wedge-like gap in the opposite direction relative to the first, frictional carrying surface. The fibers are twisted to yarn in the mouth of the wedge-like gap due to the contact with said frictional surfaces of which one is convex and the other concave. The yarn is withdrawn from said gap in a lateral direction and the twist propagation is prevented. The fibers supplied by the frictional carrying surface into the wedge-like gap are transferred, at least in a yarn preforming region followed by a yarn finishing region, immediately downstream of the mouth of the wedge-like gap, by the action of a first force onto said second frictional surface, from which the fibers after having left the wedge-like gap, are transferred by the action of a second force again onto said frictional carrying surface upstream of the mouth of said wedge-like gap.

摘要： An open-end spinning method and an apparatus wherein a flow of discrete fibers is supplied to a fiber spreading element by which they are spread over the entire periphery of an inner fiber deposit surface of a drum where a fibrous layer is continuously created. Fibers are successively withdrawn from the fibrous layer by taking off the open end of yarn and rotating it about its axis, due to a twisting moment acting on the yarn, such twisting moment being created in a region beyond the drum axis. The yarn can be given an additional twist by causing its open end to revolve about the axis of the drum. The invention enables the attainment of a high degree of the so-called cyclic fiber doubling in the spinning process, a high productivity at a relative low peripheral velocity of the operating elements of the spinning device, and the possibility of manufacturing yarns of various parameters and characteristics in one and the same spinning unit.
