Abstract
The invention solves the problem of ejecting impurities out of a cleaning aperture in the fiber separating device of an open-end rotor spinning unit, particularly when there are various contaminations of fibrous slivers and of different kinds of textile fibers being processed. For this purpose an air flow regulator is provided in the separating device in an air supply duct communicating with the cleaning aperture. According to the invention, the air flow regulator is provided with an air directing wall near the outlet of the air supply duct and thus directs air flow into the cleaning aperture toward the fiber opening cylinder.
