Abstract: The invention relates to an apparatus for processing textile fibers, comprising a processing element having a first working surface substantially in the form of a regular cylinder surface and rotatable preferably around the axis of the cylinder, like a take-in roller of a card., and at least one carding element having a further working surface facing the first working surface, wherein the form of the further working surface approximates that of the first working surface on a plane vertically intersecting the axis of the cylinder.

Abstract: A cleaning device for cleaning an all-steel sawtooth arrangement of a swift of a card has adjacently arranged sawtooth wire sections, wherein between two adjacent sawtooth wire sections a groove of the all-steel sawtooth arrangement is formed, respectively. The grooves extend from the tooth tips of the sawtooth wire sections to the groove bottom. The cleaning device has one or more cleaning elements for removing foreign particles from the grooves, wherein the cleaning element comprises a cleaning portion that is placed against the groove bottom of a groove and follows the groove when the all-steel sawtooth arrangement is moved in rotation to thereby remove foreign particles from the groove bottom.

Abstract: A method and an apparatus for manufacturing a wire, particularly a sawtooth wire for all-steel sawtooth wire card clothings, wherein the surface of a wire-shaped intermediate product, such as a wire already provided with sawteeth, is smoothened in an electropolishing process in an electrolyte bath containing an electrolyte. A relative movement is produced between the electrolyte and the intermediate product during the electropolishing process. The apparatus includes a device for producing a relative movement between the electrolyte and the intermediate product contained in the electrolyte bath.

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: In a method for producing fine wire, in particular, card wire, an optionally already treated wire blank is transformed by a heat treatment process into a drawable state, the wire blank is drawn to a drawn wire, and, subsequently, the drawn wire is subjected to a hardening and tempering process in order to obtain predetermined mechanical properties by passing the drawn wire through at least one of a furnace device and a cooling device having previously already been employed for performing the heat treatment process. The furnace device has a furnace chamber, receiving at least one wire portion, with a heat distribution block arranged in the area where the wire portion is received. The heat distribution block is designed to uniformly heat the wire portion. The cooling device has a fluidized chamber containing a flowable material. A fluid introduction arrangement is provided to introduce a fluidizing fluid into the fluidized chamber.

Abstract: A device for processing a card clothing mounted on a card clothing carrier, particularly an all-steel sawtooth card clothing carrier, has at least one processing tool and a guiding device for guiding the processing tool along a predetermined path. The guiding device has at least two guiding elements which can be adjusted between a work position and a transport position. The guiding elements extend in the work position along a longer portion of the predetermined path than in the transport position.

Abstract: An arrangement for a rotatable circular comb for processing fibers supplied in the form of a fiber band has arrangement sections fastened on a circular cylindrical mantle surface that is rotatable about an axis of rotation in a direction of rotation. The arrangement sections are arranged behind one another in a circumferential direction of the circular cylindrical mantle surface such that the arrangement sections successively engage the fiber band in an engagement sequence when the arrangement is rotated in the direction of rotation. A first one of the arrangement sections that engages the fiber band first in the engagement sequence upon rotation of the arrangement is an engagement section and the arrangement sections arranged successively behind the engagement section are follower sections. The engagement section has a lesser combing effect than at least one of the follower sections. At least one of the follower sections has a greater length in the circumferential direction than the engagement section.

Abstract: A card clothing for flats of a card with a carrier element and a plurality of card wires received with at least one received section in the carrier element, wherein each card wire has at least one processing section arranged exposed outside of the carrier element. At least in one of the card wires the received section received in the carrier element has at least the same length as the processing section which is exposed outside of the carrier.
