  • Patent number: 5448800
    Abstract: The separation of impurities through an opening in the casing of a rotating roller or drum is increased by guide grooves or guide gaps in the casing. The guide grooves or guide gaps extend in the direction of movement of the conveyed fibers and open out into the separating opening. The guide grooves may be formed directly in the casing in the surface facing the rotating roller or drum or may be formed by separate elements which are mounted on the casing and extend into the separating opening.

  • Patent number: 5423176
    Abstract: In the case of an opening roller ring member for spinning machines, teeth are integral with a ring-formed base body, the teeth being bounded by notches which extend essentially in axial direction, and by grooves which extend essentially in circumferential direction. The grooves are deeper than the notches. The lateral flanks of the teeth extend towards the tooth tip with a slope angle towards the radial line. The slope angle of the lateral flanks is smaller than the slope angle of the continuous lateral walls of the grooves, at least in the area of the teeth tips. There is a bend in the slope angle of the side walls of the grooves where the side walls join the slope angle of the lateral flanks, whereby the bend edge either coincides with the transition of the side walls into the lateral flanks, or is situated in the area of the lateral flanks.

  • Patent number: 5419952
    Abstract: Denim fabric is made from warp yarn which is at least 30% novelty cotton yarn having irregularly spaced effects (e.g. slubs) about one-half inch to two inches in length. The cotton novelty yarn is made by separating cotton sliver into cotton fibers, and acting on the cotton fibers with a negative wire combing roll, and then twisting the cotton fibers into the cotton novelty yarn. The negative wire combing roll has a tooth angle of about -0.01 to -15.degree. (e.g. about -2.degree.). The novelty cotton yarn is combined with at least 10% conventional novelty yarn or non-slub open end or ring spun yarn and made into a warp of about 54-100 ends per inch, and may be ring dyed (with indigo, vat, sulphur, pigment or reactive dye) so that the core of the yarn remains white. The warp is woven with a filling yarn to produce a denim fabric with a weight of about 5 oz. -17 oz. per sq. yd. having the weave and yarn size selected so that a tight construction is provided which highlights the slubs.

  • Patent number: 4408371
    Abstract: Doffer wire for the card clothing of rotatable doffers used in carding heads for delivering fibers to the needles of a sliver high pile fabric knitting machine having improved fiber release characteristics. The doffer wires are constituted of a shank portion, which is embedded in cantilevered fashion in the card clothing, distal portions which are raked by the knitting machine needles to remove fibers therefrom, and bent or knee portions which connect the shank portions of the doffer wires to the distal portions thereof. The knee portions are formed with an angle greater than 130 degrees and less than 180 degrees, the preferred angle being on the order of 155 degrees.

  • Patent number: 4408370
    Abstract: A fiber feeding system for feeding relatively short sliver fibers--less than one inch in length--to a sliver high pile fabric knitting machine. The system includes the usual basic elements of a carding head comprising the sliver feeding components, such as a pair of rotatable sliver feed rolls, a rotatable wire-covered doffer and a rotatable wire-covered main cylinder interposed between the sliver feeding components and the doffer. By utilizing a sliver feed plate as one of the sliver feeding components, together with one or more sliver feed rolls, the fiber pinch point may be advanced close to the periphery of the main cylinder. Where one or more pairs of sliver feed rolls are utilized without a sliver feed plate, each roll has a circumference not exceeding four times the minimum length of the sliver fibers.

    Abstract: A card clothing for carding machines, including a plurality of flexible card wires, which card wires consist of staple shaped wire sections including each a pair of legs integrally connected to each other by the staple crown, which staple legs define the teeth and which staple crown defines the base web of each card wire section, which teeth define lanes extending in the direction of the flow of the material to be carded relative to the card clothing, and which card wires are inserted in a pattern-like arrangement into a card fillet. At least two relative to the direction of material flow consecutively arranged teeth are located relative to each other at a distance extending laterally to said direction of flow which does not exceed the prevailing wire gauge of said card wire. Accordingly, the card clothing comprises no free lanes. The pattern-like arranged teeth define groups arranged consecutively with regard to said material flow.

  • Patent number: 4258454
    Abstract: Apparatus for feeding fibres, and particularly worsted fibres to a carding machine that may be a conventional worsted card or conventional cotton card. The apparatus comprises a stationary feed plate (1), a rotatable feed roller (2) and a rotatable takerin (3) for carrying fibres from the feed roller and transferring them to the surface of a carding cylinder. The surface of the takerin is furnished with pins at a pin density of not more than 36 pins per square inch (5.58 pins per square centimeter) and the distance (B) between the feed plate and the envelope of the tips of the pins on the takerin is from 0.3 to 0.75 inch (0.76 to 19.5 mm). Using this low pin density and wide spacing between the feed plate and the envelope of the pin tips effects excellent cleaning of worsted and other long staple fibre before it passes to the carding cylinder.
