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 Fibers are successively withdrawn from the fibrous layer by taking off the open end of yarn and rotating it about its axis, due to a twisting moment acting on the yarn, such twisting moment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.

摘要： A single-step stable method of producing spun-twisted yarns. A twist point is located on the frictional surface of a take-off funnel of the spinning rotor. A strand material which forms a component of the final spun-twisted yarn product is exposed, between feed rollers and said twist point, to an appropriate combination of transport effects of a pneumatic field of force and a mechanical field of force. For this purpose, the tube, through which the strand material is supplied, is determined in dependence on the pneumatic conditions prevailing in the spinning rotor.
