Spinning rotor for open-end spinning machine and method for producing the spinning rotor

摘要

A spinning rotor for open-end spinning machines and a method for balancing the spinning rotor in the course of a single clamping process by removing material from a cylindrical-shaped section of the collar (20) of the rotor cup (19) to form an identification mark (21) thereon sufficiently to offset an imbalance and equalize the mass of the rotor. The mark (21), which preferably consists of a combination of a graphic symbol (22) and lettering (23), is used for identification and information.
