Abstract: In a method for manufacturing sawtooth card clothings and all-steel card clothings for processing textile fibers in a carding process, a sawtooth wire is produced by generating teeth on a wire blank sequentially behind one another in a longitudinal direction of the wire blank, wherein the teeth extend transversely to the longitudinal direction away from a base area. The sawtooth wire is subjected at least in the area of the teeth to a hardening process under exclusion of oxygen in the area of the sawtooth wire. A device for performing the method has a heating chamber having an inlet opening and an outlet opening for the sawtooth wire passing through the heating chamber. An arrangement for generating an inert gas atmosphere in the area of the sawtooth wire passing through the heating chamber is provided.

Abstract: A circular comb for a textile combing machine has a comb member formed around a part of the peripheral surface of an essentially cylindrical support member wherein a channel is formed between the comb member and the support member. For the purpose of reducing the dynamic pressure in front of the comb member generated when rotating the circular comb, the channel is provided with a cross-sectional form wherein the radial and/or axial width increases along the rotational direction of the comb.

Abstract: A card clothing has an array of parallel elongated strips each having an inwardly directed and longitudinally extending foot part, a multiplicity of hooks extending outward from the foot part, and a pair of ends. A pair of longitudinally spaced support elements wholly out of direct contact with each other is provided, one end of each of the strips being seated in one of the support elements and the other end of each of the strips being seated in the other support element. The support elements are formed to fit with support structure of the carding machine.

Abstract: A profiled wire such as a toothed card roll wire, is made by first fitting together at least two longitudinally extending starting wires each of a predetermined cross-sectional size and each having a longitudinally extending surface region by engaging the regions together transversely and thereby forming a longitudinally extending interface. The fitted-together wires are then bonded together at the interface and the joined wires are subsequently profile pressed, that is deformed by rolling or drawing, while maintaining constant the relationship between the cross-sectional sizes perpendicular to the longitudinal direction of the starting wires. A toothed wire for a card roll can be made by further forming one of the profiled sections as a root section to be seated into a groove of the card roll and the other section as a blade with card teeth therein and hardening the formed blade section.

Abstract: A sinusoidally extending groove is cut into the jacket of a roller having a smooth surface to extend in circumferential direction thereof. A flat wire is thereafter placed into the groove. Then, a first saw-tooth wire is connected to one side of the flat wire and wound around the roller. The first turn of the first saw-tooth wire is guided by the flat wire and the subsequent turns thereof are guided by the respective preceding turn. After the winding has been completed, the flat wire is removed and a second saw-tooth wire is wound around the opposite located section of the roller. For this winding, the first turn of the first saw-tooth wire is used as guide for the first turn of the second saw-tooth wire. This leads to an optimal distribution of the tips of the clothing on the roller and an improved quality of the handling or treating, respectively, of the fibres. The roller finds use in textile machines, e.g. carding machines, opening machines, scutchers, breaker cards, etc.

Abstract: A plurality of supporting members for card clothing wires integrated in a frame and arranged directly adjacently succeeding each other in the direction of the carding forms a carding member which cooperates as revolving flat card together with a main drum. The card clothing of the individual supports can be exchanged individually and preferably a card clothing is used similar to the one of revolving flat arrangements. Accordingly the procedure when mounting and exchanging the card clothing of revolving flat cards can be simplified considerably.

Abstract: Rows of teeth which seen in direction of fiber flow trail preceding rows of teeth are laterally displaced relative thereto. The measure of displacement decreases when viewed in direction of fiber flow such that the width of the lanes also decrease in the direction of fiber flow. Accordingly, only coarser contaminants will be removed at the leading inflow area of the flat and finer contaminants will be removed in trailing flat areas. Additionally, an improved parallelizing of the fibers being carded is achieved.

Abstract: Every wire section provided with teeth of a plurality of card clothing wires is connected at both its ends by a welding to a carrier member. This carrier member is a base section of a U-shaped carrier member whereby a curvilinear extending section continues at both ends of the base section, which curvilinear sections lead into laterally extending leg sections. Every card clothing wire is welded to the curvilinear sections such that the face ends of every wire section is aligned with the outer surface of the weld beads and the outer surface with each leg section.

Abstract: Card support for carding layers, wherein the teeth are anchored in a base body made of resilient solid plastic, with reinforcing fabric layers embedded in the base body.This new type of construction is simpler to manufacture than known card supports, has better wear properties, and because of the improved recuperative capacity of the teeth leads to improved carding results.
