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).
Claims8
A method for making card roller rings, particularly for open-end spinning machines, wherein a sawtooth wire comprising a sawtooth portion extending normal to a foot portion is wound onto the ring over the length thereof and the leading and trailing ends of the sawtooth wire are secured to said ring,
- comprising winding said sawtooth wire (3) onto a tube (1) of multiple ring length (a) with said foot portion engaging the outer surface of said tube and said sawtooth portion extending outwardly therefrom, removing said teeth (7) of said sawtooth wire (3) in a circumferential plunge-cut groove (9) extending down to said foot portion (8) of said sawtooth wire (3) at spacings substantially corresponding to the ring length (a), securing said foot portion of said sawtooth wire windings (12, 13) within said plunge-cut grooves to said tube (1), and subsequently separating said tube (1) with said sawtooth wire wound thereon into individual card roller rings (2) substantially at the center of said plunge-cut grooves (9).
