Abstract
A method for making card roller rings for open-end spinning machines provides that a sawtooth wire (3) is wound onto a tube (1) of multiple ring length (a) and that the teeth (7) of the sawtooth wire (3) are removed at spacings corresponding to the ring length (a) to form a respective circumferential plunge-cut groove (9) extending down to the foot portion (8) of the sawtooth wire (3). Subsequently the sawtooth wire windings (12, 13) within the plunge-cut grooves are secured to the tube (1), whereupon the tube (1) with the sawtooth wire wound thereon is separated into individual card roller rings (2) substantially along the center of the plunge-cut grooves (9).
