Abstract:
A method for open-end rotor spinning, wherein the fibers to be spun are conveyed via a fiber guide channel (16) into the rotor (6), are collected in its rotor groove (1) of the largest interior diameter, are tied while being twisted into the yarn end in the area of a so-called tie-in zone (5) by means of the rotor rotation and are drawn off as finished yarn through a draw-off nozzle (7, 11), which is arranged centered and substantially on one level with the rotor groove (1), wherein the fiber flow exiting from a fiber guide channel (16) has a directional component in the direction of rotation of the rotor, and wherein the yarn leg (3) extending from the draw-off nozzle (7, 11) to the rotor groove (1) is curved, at least in the vicinity of the rotor groove (1), opposite the direction of rotation of the rotor during the spinning process.
