Abstract

An apparatus for open-end spinning is provided which includes a twisting element for twisting yarn. A yarn withdrawal nozzle is provided downstream from the twisting device in a yarn withdrawal direction. A yarn withdrawal device downstream from the yarn withdrawal nozzle withdraws yarn from the twisting device. A yarn deflection device is provided for deflecting yarn downstream from the yarn withdrawal nozzle. The yarn deflection device includes at least one false-twisting edge. The yarn deflection device includes a first deflection which deflects the yarn in a first direction and at least one additional deflection downstream from the first deflection which deflects the yarn into a direction deviating from the first direction.
