  • Patent number: 5839606
    Abstract: An arrangement (apparatus and method) for drawing a wire heald from a group of such wire healds of juxtaposed magnetic material. The method includes the steps of a) inserting a drawing pin located on a notch portion of a magnetic head into a guide hole formed on one side ring portion of the wire heald, b) moving the magnetic head in a longitudinal direction of the wire heald after magnetically attracting the ring portion of the wire heald, and c) drawing the lowermost wire heald as hooked on the drawing pin.
    Type: Grant

  • Patent number: 5829109
    Abstract: A stocker for wire healdes comprising a housing constructed and arranged such that a plurality of wire healds can be stacked on top of one another in a vertical direction and be arranged so as to longitudinally extend in a horizontal direction. The housing includes a heald refilling aperture at an upper portion and a heald drawing opening at a lower front portion. The heald drawing opening is positioned and configured such that a lowermost one of said plurality of wire healds can be discharged therethrough.

  • Patent number: 5826315
    Abstract: A flat heald drawing method and apparatus that draws an arbitrary flat heald out of a number of stacked flat healds. To the method a drawing pin of a magnetic head is inserted into a guide hole of a front-side ring portion of the lowermost flat heald while the flat healds are vertically stacked. The front-side ring portion of the lowermost flat heald is magnetically attracted to a tip end portion of the magnetic head. The magnetic head is moved horizontally, drawing the lowermost flat heald while hooking the flat heald on the drawing pin. The apparatus includes a magnetic head is located below a guide hole of a front-side ring portion of the lowermost flat heald and a drawing pin which is extended from a tip end face of the magnetic head. The draw pin is inserted into the guide hole of the front-side ring portion of the lowermost flat heald. A driving device holds the magnetic head and moves the magnetic head horizontally.

  • Patent number: 5737814
    Abstract: A method and an apparatus for passing a warp wound around a warp beam through a warp-passing hole of a dropper, a mail of a heald, and a reed eye includes the steps of disposing the warp-passing hole and the mail in a warp conveying passage provided between a warp beam and the reed. A tip portion of the warp is subjected to a vacuum suction and drawn through the warp conveying passage toward the reed. As the warp is drawn through the warp conveying passage, the warp passes through the mail and the warp-passing hole.
