Abstract
In the case of an open-end rotor spinning arrangement, in which the spinning rotor is arranged in a housing which is connected to a vacuum source, a fiber feeding duct is provided which extends from an opening roller to the area of a sliding surface which widens conically to form the fiber collecting surface of the spinning rotor. The smallest cross-section of the fiber feeding duct is situated at a distance from the mouth which is constructed as a slot, the height of which in the axial direction of the spinning rotor is much smaller than the ideal diameter of the smallest cross-section. The ideal diameter is defined as that diameter which corresponds to a circular area corresponding to the smallest cross-section.
