Abstract

A method for producing a rotor cup for an open-end spinning rotor includes forming separating structures on a front-side rim of the rotor cup for breaking up and preparing a yarn end for piecing. The separating structures are formed by a non-mechanical manufacturing method without contact between the front-side rim and a mechanical forming tool. A rotor cup formed in accordance with the method is also provided.
