Abstract: A method and apparatus for operating a carding machine having a drum with a drum fitting and a plurality of card flats wherein each card flat is provided with a card flat fitting. A predetermined distance between the drum fitting and the card flat fittings is adjusted by conditioning the running surfaces of the card flats.

Abstract: To improve the properties of all-steel card clothings, a saw-toothed wire is proposed with a foot portion and a plurality of teeth arranged consecutively in the lengthwise direction of the wire, the teeth issuing from the foot portion and each tooth ending in a single point, and where the interval between the points of two consecutive teeth is different from the interval between the points of other consecutive teeth.

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.

Abstract: A card clothing for cards and/or carding machines includes several coating material layers which are composed of cotton and are connected through a binding agent with each other and with an elastomer cover layer provided on one of the outer sides to form a coating material unit. The coating material layers are equipped with hooks which extend transversely of the coating material layers and extend through the coating layers in the direction toward the elastomer cover layer and protrude with their tips. For reducing the harmful influences on the carding process resulting from electrostatic charges of the coating material unit due to accumulations of fibers and/or dust in the clothing area, inhibitors which at least reduce the generation of the electrostatic charges are added in the clothing area. Embedded at least in the cover layer is an electrically conductive material which serves for discharging the frictional electricity.

Abstract: A card clothing is mounted on a support and rotatable therewith about an axis. A grinding apparatus for the card clothing has an abrasive grinding element, a base juxtaposed with the card clothing, and an elastic biasing element for pressing the grinding element radially of the axis against the card clothing so that when the support and card clothing are rotating the element grinds the card clothing. The grinding element is displaceable radially outward away from the card clothing against a force of the biasing element from a grinding position engaging the card clothing to a rest position out of contact with the card clothing. The apparatus has a mechanism for withdrawing the grinding element against the force of the biasing element into the rest position and for retaining it in the rest position. An abutment is provided furthermore for defining a position of closest approach of the grinding element to the axis and hence, how much it will grind down the card clothing.

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: The saw tooth strips which form the card clothing are supported in bar shaped carriers. The carriers are mounted in the frame. This frame includes a blade supporting section for a dirt removing blade. The angular position of the blade relative to the carding cylinder can be adjusted by shims placed selectively onto projections at the blade supporting section. The blade is mounted by set screws to the frame. These set screws project through oblong holes through the blade such that longitudinal adjustments of the blade is possible allowing an adjusting of the distance between the blade knife edge and a carding cylinder.

Abstract: A saw tooth all-steel card clothing which includes a foot section followed by a web section including the teeth. The total height of the foot and web section amounts to less than 2.0 millimeters and more than 0.5 millimeters, and the ratio of the total height to the height of the foot amounts to less than 1.8.

Abstract: Each saw tooth wire strip is provided with a plurality of angular bends forming a plurality of strip sections. The strip sections located at the leading and the trailing end of the wire strip extend parallel to the direction of fibre flow. The intermediate strip sections extend inclined thereto. This allows a setting of a higher number of teeth in the card clothing. Also, a highly improved performance of the opening of neps as well as parallelizing of the fibres is achieved. The wire stips are threaded onto an elongated carrier member and are locked thereonto by means of a locking member in a prestressed state. It is, therefore, not possible that individual wire strips can be torn off by any forces acting thereupon leading to damages of the machine.

Abstract: The teeth of the saw tooth wire of the card clothing are provided with a discontinuity. This discontinuity is located at the tip section of the teeth and at its trailing edge. The discontinuity forms an obstacle member retaining the fibers for a prolonged time on a corresponding drum of a textile machine. This leads to an improved random orientation of the fibres in the fibre fleece leading finally to a more stable non-woven product.

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.
