ABSTRACT:
In an arrangement for open-end rotor spinning, it is provided that a fiber feeding duct, starting from its end located opposite a fiber sliding surface of a spinning rotor, is opened up by means of a lateral slot so that the cross-section that is essential for the taken-in air quantity is placed back in an area with a larger diameter, while, in addition, the end area of the fiber feeding duct is designed as a narrow groove.
