Abstract: In the mounting device (1) in accordance with the invention, the mounting arm (4) is held on a guide arrangement (11), the guide direction of said guide arrangement being oriented parallel to the rotational axis of the drum (3) to be fitted. A force measuring arrangement 21 is provided to detect the tensile force in the profile wire 9, said force measuring arrangement detecting the total force acting on the mounting arm (4), at least in longitudinal direction of the wire. In doing so, essentially all the forces acting on the profile wire (9) are detected, namely, the braking forces of a brake arrangement (25) as well as the braking forces of other arrangements such as, for example of alignment arrangements 28, tilting arrangements 32 or the like.

Abstract: A sawtooth wire for producing an all-steel sawtooth arrangement for processing textile fibers has a wire body having a plurality of teeth arranged successively in the longitudinal direction of the wire body. Each tooth has a tooth bottom and a tooth tip, wherein a tooth breast extends from the tooth bottom toward the tooth tip and a tooth back starts at the tooth tip and extends toward a successive tooth bottom of the successive tooth. The tooth back of at least one of the teeth has one or more convex portions passing over into a concave portion, respectively, in a direction toward the tooth bottom.

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).
