Abstract
A process for open-end spinning provides for at least one sliver being opened into single fibers. A wide fiber veil is formed from parallel single fibers extending in the direction of motion, which fiber veil is fed to a transporting surface by means of a moving collecting surface. The single fibers are transferred from the collecting surface to the transporting surface at a transfer point, whereby the direction of motion of the fiber veil is abruptly changed, however the current relative position of the single fibers remaining essentially constant. This motion direction change occurs at the transfer point, with the respective front part of the fiber veil being transferred to the transporting surface as a fiber group in a predetermined sequence, and the transporting surface moves transversely to the direction of motion of the collecting surface. The single fibers are then transported by means of the transporting surface to a spinning line, which is situated on the transporting surface and extends transversely to the direction of motion thereof and along which the forming yarn is withdrawn. Due to the sequenced transfer point and the selected directions of motion of the collecting surface and the transporting surface, the single fibers can be bound into the yarn essentially parallel to the spinning line.
