ABSTRACT:
A process for surface treatment and wear resistant coating of opening rollers for open end spinning of the type having a basic metallic body and a raw wire clothing, includes the steps of introducing the opening roller into a sealing bath in such a way that this sealing bath fills even the smallest voids between the raw wire and the basic body of the roller, rinsing off the opening roller clean on the outside, heat treating the opening roller, and subjecting the opening roller thus pretreated to deburring and antiwear coating in a conventional manner.
