Abstract: A top comb for a comber has a longitudinally elongated support element extending transverse to a combing direction and a plurality of comb teeth fixed next to one another in a longitudinally extending row along the support element. Each tooth is formed at least partially as a sawtooth-wire segment having at least one sawtooth in turn formed with a pair of longitudinally oppositely directed side flanks extending parallel to the combing direction and a front longitudinally extending tooth face bridging the respective side flanks.

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 sawtooth wire for an all-steel fiber-working clothing is formed unitarily with a longitudinally extending foot having a longitudinally extending base surface and a blade extending from the foot and formed with teeth having tips. The blade tapers uniformly outward from the foot toward the tips. The teeth are symmetrical to a plane extending longitudinally and perpendicular to the base surface.

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: A method and apparatus for hardening discrete identical elements, connected to a supporting structure and regularly spaced, by which a laser beam is focused upon the elements as they travel along a path through a hollow sphere containing a mirror on its inside surface. The light reflected by the elements is reflected by the mirror to strike the opposite side of the elements. This process optimizes the radiant energy directed to the elements and produces quick, uniform, well-delineated hardening substantially without a hardness gradient.

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: 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: The wire sections forming the wire package are arranged on a profile. The individual wire sections are interconnected by means of an adhesive tape adhered to their feet. A T-slot is located in the profile. Accordingly, the adhesive tape contacts at no place the profile. A locking member is located at one end of the profile. This locking member engages by means of protrusions into the slot. The profile comprises an arresting member. The locking member is clamped onto the arresting member. A recess at the end of the locking member facing the wire package allows an impeccable abutting of the locking member on the wires. The wires comprise smooth, toothless end sections having surface areas extending obliquely inwards. This allows the clips, by means of which the card clothing is clamped onto the flats, to safely grip around the ends of the wires and the locking member to hold them clampingly against the profile.

Abstract: A plurality of wire sections are lined up side by side on a carrier member. Every wire section comprises a row of teeth, a distance piece section, a web located below thereof and a foot section. A through opening is provided in the web section. The two ends of the carrier member are provided with a slot-like opening. A locking member having the form of a block is slid onto the two ends against the wire sections held in a prestressed condition. This block-like structure comprises a rectilinearly extending longitudinal bar and a further longitudinally extending bar deformed into the slot-shaped through opening. This deformed bar acts as locking element. Accordingly, the wire sections package arranged upon the carrier member is held locked in a prestressed condition. Because these wire sections are not held by means of a welding or by means of an adhesive agent on the carrier member, savings regarding costs and materials are achieved.
