Definitions

  • a weaving shuttle for picking weft threads into the shed on a loom which comprises an elongated body, a passage extending through said body, thread-holding means positioned in said passage whereby a weft thread, upon being inserted into the shed by the shuttle, is held within said passage, so that a free end of the thread extends from the side wall of the shuttle on the reed side of the loom, and a recess on the reed-side wall of said body, the recess extending over the entire width of said body and extending, in the longitudinal direction of the said side wall, over at least the zone on the body covered by the free end of thread projecting from the shuttle during its movement through the shed.
  • the present invention relates to a weaving shuttle for picking weft threads into the shed and in particular to a shuttle by which the weft thread, upon being drawn into the shed by the shuttle, is held in an opening passing through the shuttle in such maner that a free end of the thread protrudes from the side wall of the shuttle on the reed side.
  • the object of the present invention is to prevent the free end from being trapped or frayed. This is achieved by providing, in the wall of the shuttle on the reed side, a recess which extends over the whole width of this wall and, in the longitudinal direction of this side wall, extends over at least the zone of the end of the thread projecting out of the moving shuttle.
  • FIGURE 1 shows a plan view of one embodiment of the weaving shuttle of the invention
  • FIGURE 2 shows an elevational view of the embodiment shown in FIGURE 1, as seen on the side facing the reed;
  • FIGURE 3 shows a plan view of another embodiment of the shuttle.
  • FIGURE 4 shows an elevational view of the embodiment shown in FIGURE 3, as seen on the side facing the reed.
  • FIGURES 1 and 2 show a shuttle 11.
  • the shuttle 11 lies against the reed which is represented by the dents 12.
  • the reed is secured to the sley 20.
  • Shuttle 11 has an elongated body and is provided with two openings or passages 13 extending completely therethrough. In relation to the middle of the shuttle, the openings 13 are arranged symmetrically along the longitudinal direction of the body of the shuttle.
  • a thread holder or thread clamp 14 is positioned in each of the openings 13. The two small plates of the holder 14 are pressed towards each other by means of the springs .19.
  • a pin 15 serves to define the position of the thread laid into the holder 14.
  • the shuttle 11 also has a projection 22 extending over its length upon which act the guide elements (not illustrated) for guiding the shuttle 11 during its flight. When the shuttle 11 is being driven, the picking stick acts upon the end surfaces 21.
  • a recess or sunken portion 17, (see FIGURE 1) is provided on that side of the shuttle 11 which faces the reed 12. Sunken portion 17 extends towards the tips of the shuttle on both ends and over a zone which extends somewhat beyond the two thread clamps 14. Furthermore, a covering 16, of bristles, nap, plush or the like fibrous material is provided in the recess 17.
  • FIGURE 1 shows the position of a thread 18 carried by the shuttle 11 during its flight through the shed.
  • the portion of the thread 18 present on that side of the shuttle 11 facing away from the red 12 extends to the apparatus (not illustrated in the figure) for measuring out threads to a prescribed length.
  • This apparatus is mounted on the weaving loom, and the thread is drawn off from it.
  • the free end 18' of the thread which projects from the side of the shuttle 11 on the reed side is located in the free space formed by the recess 17 during the flight of the shuttle, so that it cannot be trapped between the dents 12 of the reed and the wall of the shuttle on the reed side.
  • the recess 17 should extend over the entire width of that side wall of the shuttle 11 located on the reed side.
  • a layer 16 of fur, plush or the like is provided in the recess 17.
  • This fibrous covering 16 extends over at least a part of the recess and advantageously, over the part lying between the ends of the two openings 13 most adjacent the center of the shuttle.
  • the length of the fibers is such that the thickness of the covering 16 is at least equal to the depth of the recess 17.
  • the recess 17 extend from the middle of 3 the shuttle further to the left and right than the loca tion of the thread clamps 14.
  • a shuttle 11' which has, at the middle of its elongated body, a single opening 23 for guiding in the weft thread 18.
  • thread clamps or holders 14 which are each formed by two small plates which are pressed towards each other by means of springs 19.
  • the pins 15 define the rearmost position of a thread 18 introduced into the clamp 14.
  • This embodiment of the shuttle also has a projecting portion 22 for guiding it with the help of guide elements, while the shuttle 11' is moving through the shed.
  • shuttle 11' is driven by means of a picking stick applied to the end faces 21.
  • shuttle 11' has two recesses 27 on its side directed towards the reed.
  • Each of these recesses or sunken portions 27 extends over a certain distance from one of the thread clamps 14 towards the end of the shuttle adjacent this thread clamp. This prescribed distance is at least as long as the free ends 18' of the weft threads 18 carried along 'by the shuttle 11'.
  • the sunken portions 27 be provided with a covering 26 of bristles, fur or the like fibrous material.
  • a weaving shuttle for picking Weft threads into a shed of a loom which comprises an elongated body, a passage extending transversely through said body, threadholding means positioned in said passage for holding a portion of a weft thread in the vicinity of its free end whereby upon insertion of the thread into the shed by the shuttle the free end of the thread projects from that portion held in said passage along the side wall of the elongated body on the reed side of the loom and a recess of the reed-side wall of said body, said recess extending over the entire width of said body and extending in the longitudinal direction of said side wall from said passage, in a direction opposite to that of the movement of the shuttle during picking of the weft thread over a zone of the body which is covered .by the free end of the thread projecting from the shuttle during movement through the shed.
  • the weaving shuttle of claim 1 further comprising a layer of fibrous material extending over at least a part of the recess.
  • said weaving shuttle of claim 1 in which said passage is arranged in the middle of the body of said shuttle, said thread holding means comprise two thread-holding devices, each positioned at the ends of the passage remote from the middle of the shuttle body, and two recesses are provided in said body, each of which extends over a prescribed distance from the location of one of the thread-holding devices towards the end of the shuttle adjacent to said one of the thread-holding devices.
