Abstract: Metallic wire card clothing is provided having a sharpened leading edge on each of the longitudinally aligned teeth formed in a metallic strip by an apparatus which includes a punch. During punching, the relative direction of travel of the punch is illustrated as inclined at an acute angle in relation to the moving strip and a die cooperating therewith. The method contemplates thus inclining the strip and while the strip is so inclined, punching the teeth as the strip is continuously fed past the die. The strip may be inclined in respect to the direction of travel of the punch either transversely or longitudinally, preferably, both.

Abstract: An apparatus for stripping a carded web from a doffer cylinder of a textile carding machine comprises a roller arrangement which consists of a card clothed doffer cylinder, a stripping roller clothed with a scatteredly toothed metallic wire, a pair of top and bottom rollers arranged successively to the stripping roller, and an auxiliary stripping roller clothed with a scatteredly toothed metallic wire disposed close to the stripping roller and above the top roller, wherein the top and bottom rollers rotate at the same surface speed as that of the stripping roller, while the surface speed of the auxiliary stripping roller is lower than that of the stripping roller; the top roller, stripping roller and the auxiliary stripping roller rotate in the same direction; and furthermore, the distance between the bottom roller and the stripping roller and the distance between the top roller and the stripping roller are both narrow.

Abstract: An electroplated combing roller for use in a spinning unit of an open end spinning machine comprises an aluminum alloy cylindrical body, and a steel wire fixedly mounted in the cylindrical body. A hardened chromium plating is carried out after mounting the steel wire onto the aluminum alloy cylindrical body and the dimensions of the steel wire and aluminum alloy cylinder are interrelated in a manner such that only the exposed surface of the steel wire is plated with the hardened chromium while the exposed surface of the aluminum alloy cylinder is not so plated.

Abstract: A method of manufacturing flexible card-clothing for use in textile carding comprising the steps of producing a foamed polyvinylchloride compound having a density of between 0.6 and 1.00 grams per cubic centimeter; applying a sealing coat of a material which is compatible with the foamed compound to a fabric layer; applying a layer of the foamed p.v.c. onto the seaing coat to produce a finished foam layer of between 2 and 5 millimeters thickness on the fabric; heating the applied foamed layer to p.v.c. to cause the foamed layer to fuse; applying a surface layer of sealing material onto the exposed surface of the foamed layer to provide a smooth non-absorbent external surface, with the fabric, foamed p.v.c and surface layer together forming a composite foundation face, combining the foundation face with a foundation back to form a laminated foundation, and then inserting card-clothing wires into the foundation so that parts of the wires project from the surface layer.

Abstract: This spinning machine weighs about 10 lbs. and is of about the size of a one foot cube. The reel on which the spun yarn is to be stored is contained within a large horizontal tube. The yarn is fed through a hole in the wall of the tube from a groove on the outer surface. The reel is rotated by running on the inner surface of the tube which is driven by, for instance, a sewing machine motor. By control of dimensions or by braking a relative speed is imposed between the reel and the tube and is the speed for reeling yarn. The yarn is fed to the groove from two small tubes, one stationary and the other rotating with the large tube. Both are coaxial with the large tube. Locks or sliver to be spun are presented to a surface with saw-tooth corrugations alternating with slots, and is fed to the stationary small tube.

Abstract: A roller train in a carding machine comprises first, second and third card-clothed rollers, the second roller having two sets of teeth pointing in opposite directions, and the relative surface speeds of the rollers being such that one set of teeth on the second roller has point-to-point action with the teeth in the first roller and the other set of teeth on the second roller has point-to-point action with the teeth on the third roller.

Abstract: Apparatus for blending, paralleling and cleaning fibers such as cotton and synthetics. The apparatus comprises a work roll having its surface covered with metallic wire and an arcuate, metallic wire section cooperating with a portion of the periphery of the work roll. The fiber is fed between the roll and arcuate surface, accomplishing the improved results noted in the accompanying specification.

Abstract: A card clothing foundation, to which the carding wires are fitted, has an anti-friction surface layer of polyurethane about 0.006 inch in thickness and containing silicone.
