  • Patent number: 7520303
    Abstract: A method for weaving a fabric having: a backing fabric (100, 200) formed by backing warp yarns, having binding warp yarns (101, 201) and first and second weft yarns (3, 4); one or several tension warp yarns (102, 202, 103, 203); and non-pattern forming and/or pattern forming pile warp yarns (7, 6), the pattern forming pile warp yarns (6) form pattern forming pile burls (6a), and each pattern forming pile burl (6a) is interlaced round at least one third weft yarn (5) situated at the back of the fabric (1, 2) with respect tote tension warp yarns (102, 202, 103, 203).

  • Patent number: 7395839
    Abstract: The present invention relates to a method for face-to-face weaving of a pile fabric on a weaving machine, pile forming pile warp yarns (6, 7, 8, 9, 16, 17, 18, 19) being interlaced alternately around a weft yarn (1) in the upper fabric and around a weft yarn (1) in the lower fabric and non pile forming pile warp yarns (6, 7, 8, 9, 16, 17, 18, 19) being interlaced in one of the backing fabrics in accordance with a predetermined pattern, the said weaving machine comprising at least three weft insertion means and that at each weft insertion cycle only one weft yarn is inserted, the non pile forming pile warp yarns (6, 7, 8, 9, 16, 17, 18, 19) to be interlaced are positioned on a different level (N1, N2) and, in successive series of four weft insertion cycles (a, b, c, d) each time during two successive weft insertion cycles one weft yarn (1) being inserted (a, b) under the two levels (N1, N2) and one weft yarn (1) being inserted above the two levels (N1, N2) and each time, during two other successive weft insert

  • Patent number: 7117897
    Abstract: A method and apparatus for face-to-face weaving of an upper and a lower fabric on a face-to-face weaving machine, upper and lower fabric (101, 102) comprising at least a first zone with pile loops, the pile loops being formed around one or several lost pile loop weft yarns (16, 16?), and comprising at least a second zone where no pile loops are formed around lost pile loop weft yarns and catch means (1, 1?) being provided for supporting the lost pile loop weft yarns (16, 16?) within the second zone in one or several areas in the weft direction where no pile loops are formed around these lost pile loop weft yarns (16, 16?).

  • Patent number: 6234212
    Abstract: A pile loop forming assembly for looms for reliably transferring yarn from one side of the lance to the other in order for the yarn to be wrapped around the lance to form a loop. The loops may be cut by a blade as the loops advance and ride over the blade edge. The loops are formed by yarns passing through reed fingers wherein lances move the yarn from one side of the reed finger to the other. The lances are attached to a bar, which moves linearly in alternate directions so as to wag the lances to either side of the reed space. A heald moves the yarn up or down to selectively engage or disengage from the lances. A guide formation on a portion of the reed space helps deflect the yarn from one side of the lance to the other. The reed can pivot between a beat-up position and a weft insert position. As the reed moves to the beat-up position it engages the newly formed pile loop on the lance and pushes it to the fell.

  • Patent number: 6192943
    Abstract: A loom for weaving pile fabric is disclosed, including a plurality of healds for shedding warp yarns, a pile-forming reed through which said warp yarns are guided and a plurality of pile loop forming lances extending in the warp direction so that each pile-forming lance passes through an associated dent in the read, each dent being defined between a pair of spaced apart dent fingers. Each loop forming lance and at least one dent finger of said pair of dent fingers cooperate to guide lateral displacement of the loop forming lance relative to said associated dent. A first group of healds are threaded with ground forming warp yarns and the first group of healds and the loop forming lances are arranged such that the upper and lower shedding positions of said ground forming warp yarns are located below the loop forming lances.

  • Patent number: 4706715
    Abstract: An improved mandrel for use with a weaving loom for the formation of loops of a looped fabric suitable for use as a surface-type fastener generally known as a loop-and-hook fastener. The mandrel has a generally V-shaped first recess defined in an upper longitudinal edge thereof and adapted to be disposed adjacent to the fell of a foundation fabric while being woven on the loom, for receiving individual loops therein before they are tensioned on a loop-setting portion. Since all the loops are received in the recess irrespective of their initial looping positions, a warp thread forming loops does not interfere with a weft thread forming a part of the foundation fabric and the loops are placed in a desired upstanding position when tensioned on the loop-setting portion.

  • Patent number: 4532965
    Abstract: The weft yarn picking channel is constructed for use in pneumatic weaving machines. In one embodiment, the picking channel is formed of discrete guide elements of wire construction which are secured on a sley. In another embodiment, the guide elements can be incorporated in a reed via bends in the reed wires.
