Wire Control Patents (Class 139/40)
  • Patent number: 7451786
    Abstract: The invention relates to a weaving machine for weaving pile fabrics, and a set (100) of at least two spacers (1-4, 11, 12, 21, 22, 31, 32, 41 and 42), wherein the spacers (1-4, 11, 12, 21, 22, 31, 32, 41 and 42) are provided and arranged in the weaving machine in such a manner that the pile warp yarns (18, 18?) have more space during their movement in the shed-forming zone towards the fabric line in the warp direction at their entry point in the array of lancets, so that they are hindered to a lesser degree by this array of lancets.

  • 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: 7111647
    Abstract: A weaving machine weaves pile fabrics having weft yarns, backing warp yarns, and pile warp yarns. One or several spacers extend between the pile warp yarns either to realize a constant pile height between two pile fabrics formed, or to determine the pile loop height in one or several pile fabrics comprising pile loops. One or several holders clamp the spacers. One or several shed forming devices, drive heddles through which backing and/or pile warp yarns extend to position these warp yarns with respect to the weft yarns. A zone for supplying pile warp yarns extends between a yam supply and the heddles. One or several holders installed between the yarn supply and the one or several shed forming devices clamp the spacers. The holders are installed outside the said supply zone, in such a manner that the pile warp yarns will extend into the supply zone without any hindrance.

  • Patent number: 4915138
    Abstract: Method of weaving pile fabrics by means of pile wire looms, wherein the fabric has a pile loop every n wefts, n being greater than or equal to 2, and wherein each of the pile wires is inserted in an insertion cycle which takes place during one weft cycle and are each extracted, one after the other, in an extraction cycle which takes place over n successive weft cycles. Apparatus for applying this method comprises at least two extraction and one insertion carriage. In addition, the apparatus has a transfer device which consists essentially of a fixed pile wire bar and a movable pile wire bar. The two pile wire bars are provided on their mutually facing longitudinal sides with a guide track over which the pile wires make their extraction movement and insertion movement.
