A method of hardening a clothing wire for processing textile fibers and to an apparatus system therefor. The clothing wire has a succession of teeth arranged in its longitudinal direction, and the clothing wire is guided through a heating region in a pass-through direction for contact with at least one open flame. The heating region is followed by a quenching bath having a quenching liquid and by a subsequent tempering apparatus. The clothing wire moving in the pass-through direction is flushed around with a protective medium in a transition region between the region of contact with the open flame and the entry into the quenching liquid.

A sawtooth wire in which each tooth has a tooth tip and a tooth front having a first segment extending from the tooth tip towards a tooth side remote from a bearing edge and towards the tooth back and merging into a concave second segment that merges into a third segment extending towards the tooth side and merging into a concave fourth segment. that merges into a tooth back of the next tooth. The length of a tangent from a turning point of the second segment to the tooth side is greater than or equal to half the spacing between the tooth tip and the tooth side.

A circular comb of a combing machine has a base body oriented parallel to a rotational axis of the circular comb, the base body including an inner support surface and a radially oriented opening. A comb element is disposed on an outer circumference of the base body, and a retaining element having a threaded bore is connected to the comb element. A threaded bolt has a threaded first section that engages into the threaded bore, a middle section that protrudes through the radially oriented opening the in base body, and a second end section supported on the inner support surface of the base body. A diameter of the first end section of the threaded bolt is smaller than a diameter of the middle section. A spring element is provided between the inner support surface of the base body and the second end section of the threaded bolt.

An all-steel clothing for a flat card or roller card for processing textile fibers includes a sawtooth wire having teeth arranged one after another in a wire running direction. The tooth contour of the teeth is defined, starting from a tooth base, as at least transitioning into a tooth back, further transitioning into a tooth tip portion, further transitioning into a tooth face and again transitioning into a subsequent tooth base. The tooth tip portion has a predetermined tooth tip length (L) in the wire running direction and a tooth prominence on top of a part of the tooth tip portion. The tooth prominence has a tooth prominence length (l) which is less than the tooth tip length (L).

A card wire has consecutive teeth spaced apart in the longitudinal direction by a pitch. The teeth are bounded in the longitudinal direction by a tooth face on a first side and by a tooth back on a second side. Looking downwards in the height direction of the card wire, the tooth face and the tooth back of consecutive teeth merge in a tooth base and, looking upwards in the height direction, form a tooth tip. The tooth depth is defined by the greatest distance, in the height direction of the card wire, from the tooth tip to the tooth base. The ratio of pitch to tooth depth is less than 1.1. An interspace, measured at right angles to a tangent to an inflection point between tooth back and tooth base, between this inflection point and the opposite tooth face is greater than a quarter of the pitch.

A threaded bolt has a threaded first section that engages into the threaded bore, a middle section that protrudes through the radially oriented opening the in base body, and a second end section supported on the inner support surface of the base body. A spring element is configured with the middle section of the fastening element and includes a first end supported on a support surface of the second end section of the fastening element, and a second end supported on the support surface of the base body. In one embodiment, the retaining element comprising a detent point into which the first end section of the fastening element is transferred by a longitudinal displacement of the fastening element against an elastic force of the spring element.
