ABSTRACT:
An opening roller and a process for making an opening roller for open-end spinning machines is disclosed where wavy shaped toothed rings and intermediate rings are alternately slid on a preferably cylindrical part. The toothed rings and the intermediate rings are clamped between axial stops. It is provided that during the clamping of the toothed rings and the intermediate rings between the axial stops, the intermediate rings are plastically deformed. Thus it is achieved that without narrow manufacturing tolerances, the toothed rings and the intermediate rings rest against one another without gaps so that fibers cannot be caught during use of the opening roller.
