Abstract

A spinning rotor for an open-end spinning device is proposed which is provided with a smooth surface at the critical locations in order to avoid deposits within the spinning rotor at its inner surface. The ring-shaped zone of the inner surface of the spinning rotor near its edge as well as the area of its bottom may for instance be made especially smooth by polishing.
