Definitions

  • the invention relates to weaving machines and, in particular, a device for presenting a weft in front of a weft pass needle, a device which is situated between a weft pass eyelet and the edge of the fabric.
  • the weft is inserted into the crowd of certain weaving machines using two weft pass needles, an input needle and an output needle moved back and forth. reverse.
  • the input needle must grip the stored weft thread coming from a reserve located outside the machine. To pick up the weft by the weft pass, it is necessary to present it at a well-determined location corresponding to the pinch point of the weft pass.
  • the first installation of the weft in the clamp is done manually before starting the machine.
  • a clamp and wire cutter member oscillating on a horizontal axis carrying a clamp and a knife perpendicularly on this axis, is combined so as to pinch the weft firstly, to cut it once pinched.
  • This organ is controlled at each cycle by the leaf.
  • the pliers and thread cutters open like scissors. This organ is controlled by the wing. Meanwhile, the weft has slipped into a beak of the pliers and wire cutters, the assembly closes, the wefts are folded down, pinched and cut. The cycle can start again.
  • the clip and wire cutter member is mounted on the leaf and follows its movement; a fixed ramp fixed to the machine frame controls the opening and closing of the pliers and the wire cutter. This maneuver is carried out near the neutral point before, after the exit and before the entry of the weft-passing needle into the width.
  • the object of the present invention is to remedy these drawbacks.
  • the device comprises: at least one folding, pinching and presentation mechanism in front of the needle of the portion of the weft included between a guide eyelet and the edge of the fabric; and a weft end cutting mechanism located near the edge of the fabric, each of said mechanisms being carried by a fixed part of the frame of the loom and being actuated individually by a cam rotating in synchronism with the main shaft of the loom.
  • the mechanism for folding down, pinching and presenting the frame is constituted by a first mechanism for folding down the frame and by a second mechanism for pinching and presenting the frame, each of said first and second mechanisms being carried by a fixed part of the loom frame and being actuated individually by a cam carried by a rotating shaft in synchronism with the main loom of the loom, the cutting mechanism constituting a third mechanism which is actuated by a third cam carried by a rotating shaft in synchronism with the main tree.
  • the three cams of the three mechanisms are mounted side by side on a common shaft rotating in synchronism with the main shaft of the loom.
  • the invention also relates to weaving looms equipped with such a weft presentation device.
  • the weft T is kept tensioned between two pinching points by the fabric a) on the one hand and by a tensioner b) on the other hand, the weft coming from the reel 0) which is located outside b).
  • a tensioner b) Next to the tensioner b) and between the width a), a fixed eyelet d) in the case of single weft or an eyelet d) movable in the case of a weft mixer positions the weft always in the same place, as it is classic.
  • the second end 23b is connected to a crank 24, itself fitted on the control shaft 16; an inclined bearing 25, which is integral with the frame 7 ; maintains the control shaft 16 in position.
  • Said axis 16 is provided at its upper part with a nut 26 which is adjustable in rotation and longitudinally relative to the control axis 16. This nut 26 carries the hook 14 which is also adjustable in rotation.
