ABSTRACT:
A process for operating an open-end friction spinning machine is provided in which the spinning units each have at least two friction areas that form a yarn-forming region. At least a part of the friction effect is determined separately for each friction surface. The friction effect is compared between such friction surfaces. A corresponding open-end friction spinning machine apparatus is also provided.
