Definitions

  • the present invention generally relates to Jacquard machines, and particularly to the arrangement or system of pulleys, pulley cords and hooks for forming a shed in the warp threads, as used in carpets face-to-face weaving.
  • a pulley arrangement comprising for forming a shed in the warp threads of a Jacquard machine, a plurality of pulley elements and a plurality of complementary hooks connected by means of a plurality of vertically movable pulley cords, such that control of a suspension point of the pulley cord enables a selection of four possible positions for the warp threads for at least each of two picks.
  • Each pulley, arrangement works together with one set of two of the complementary hooks, and comprises a pulley element with top and bottom roller connected above one another and suspended below each set of the complementary hooks by means of a first pulley cord, each end of the first pulley cord being fixed to one of the complementary hooks, while downward-hanging portion of the first pulley cord runs over the top roller of the pulley element, thereby suspending said pulley element, one end of the second tackle cord being attached to one of the complementary hooks, with another end of the second pulley cord being attached to a first deflection roller, and guided over said deflection roller is a third pulley cord having one end connected to a fixed point of the Jacquard machine, a portion of the third pulley cord guided over the first deflection roller, runs back up over a second deflection roller and guided over the bottom roller of the pulley element, with another end of the third pulley cord being connected to one or more warp threads by means of a plurality of harness
  • the tackle suspension system consists in that in a first possible embodiment (see Fig. 1) the two ends of a first pulley cord 113 are fixed at the bottom side of each of the hooks 111 and 112 forming a set of complementary hooks, said first pulley cord 113 hanging down in a loop.
  • a pulley element 114 with its top roller 114' is hung in said loop.
  • One end of a second pulley cord 115 is affixed to the bottom side of one of the complementary hooks 111, and it's other end being connected to a first deflection roller 121.
  • a third pulley cord 118 Over the first deflection roller 121 lies a third pulley cord 118, one end of which is connected to a fixed point of the Jacquard machine 116 disposed lower down than the pulley element 114.
  • the third pulley cord 118 is further made to hang lower down than a second deflection roller 117 in a loop, extends up and laid over the bottom pulley roller 114' and then down, connected to one or more warp threads 120.
  • the second deflection roller 117 is supported from below by a fourth pulley cord 122 connected to a second up and down movable grid 119.
  • the grid 119 is coupled (by any known means -- not shown) to any of the hooks 111 or 112.
  • Fig. 2 shows schematically a second possible embodiment of the pulley tackle arrangement with a pair of complimentary hooks according to the invention.
  • first and second pulley elements 214 and 216 are suspended directly by first and second pulley cords 213 and 215 from their top rollers 214' and 216' at the bottom side of the complementary hooks 211 and 212, respectively.
  • Fixed to the bottom pulley roller 216'' of the second pulley element 216 is the end of a third pulley cord 218 which is made to hang lower down in a loop, around the first deflection roller 217, is taken back up and laid over the bottom pulley roller 216'' of the second pulley element 216, and the other end is then fixed to a second deflection roller 221, to suspend it.
  • the first deflection roller 217 is suspended in the loop formed with the third pulley cord 218, and fixed by a fixed cord 225 to the first grid 219 disposed horizontally lower down, while this grid being disposed movable up and down with one of the knives 211' and 212'.
  • the fourth pulley cord 223 hangs over the second deflection roller 221, extends down in a loop over a third deflection roller 222, then hangs over the bottom roller 214'' of the first pulley element 214.
  • One end of the fourth pulley cord 223 is connected to a second grid 224 movable up and down with one of the knives 211' and 212', and it's other end is connected to the warp threads 220.
  • the third deflection roller 222 is suspended in the loop formed with the fourth pulley cord 223 and coupled to the fixed point of the Jacquard machine 226 directly by means of fixed cord 227.
  • FIG. 1 Another possible embodiment of the pulley arrangement with two sets of complementary hooks is shown in Fig 3.
  • first and second pulley cords 315 and 316 are fixed to the bottom sides of two sets of complementary hooks 311, 312 and 313, 314, respectively.
  • the pulley cords 315 and 316 hang down in loops around top rollers 317' and 318' of first and second pulley elements 317 and 318.
  • a fourth pulley cord 319 hangs down in a loop over a third deflection roller 320', being top roller of pulley element 320, then hangs over the bottom roller 317'' of the first pulley element 317.
  • One end of the pulley cord 319 is connected to a fixed point of the Jacquard machine 321 and its other end is connected to the warp threads 322.
  • the pulley element 320 with its deflection roller 320' is now suspended in the loop formed with the fourth pulley cord 319.
  • Fig. 4 shows schematically another possible pulley arrangement according to the invention.
  • This modification is provided with three sets of complementary hooks 411 and 412, 413 and 414; 415 and 416, three pulley elements 417, 418 and 419 and three separate deflection rollers 420, 421 and 422.
  • Each of the first, second and third pulley elements 417, 418 and 419 comprises two rotatable rollers which are fixed to each other located one above the other in a common plane by a mechanical mounting of their shafts.
  • the first, second and third pulley elements 417, 418 and 419 are suspended below each of sets of the complementary hooks by means of first, second and third pulley cords 426, 427 and 428.
  • Each end of the first pulley cord 426 is fixed to one of the hooks of the first set of the complementary hooks, each end of the second pulley cord is fixed to one of the hooks of the second set of the complementary hooks and each end of the third pulley cord is fixed to one of the hooks of the third set of the complementary hooks.
  • Each warp thread 423 is now connected by means of the harness cord to the bottom end of a fifth pulley cord 424.
  • the fifth pulley cord 424 runs over a third deflection roller 422 and is directed back downwards, with the other end thereof being connected to a fixed point of the Jacquard machine or grid 425.
  • the third deflection roller 422 is suspended directly by a third pulley cord 426, which runs over the bottom roller 419'' of the third pulley element 419 and directed downwards. Then it hangs down in a loop over a second deflection roller 421, hangs over the bottom pulley roller 418'' of the second pulley element 418 and runs down in a loop over a first deflection roller 420.
  • the second end of the pulley cord 426 is fixed to the bottom roller 417'' of the first pulley element 417.
  • the first and second deflection rollers 420 and 421 are disposed in a fixed manner by any conventional means (not shown
  • the two backing fabrics comprise binder warp threads (7) and (7') and (8) and (8') respectively and tight warp threads (9) and (10) respectively.
  • the pile warp threads forming the pile are woven between the two backing fabrics which are held at a certain distance from each other, while the dead pile warp threads are bound into either the top fabric or the bottom fabric.
  • a pile warp thread until then forming the pile is bound into the top fabric or bottom weave at a particular weft insertion, and a pile warp thread which has been dead until then can begin to form pile at a particular weft insertion.
  • the three pile warp threads are indicated in Fig. 5 by P1, P2 and P3.
  • the pile warp thread P1 is provided for binding into the top weave.
  • the pile warp threads P2 and P3 are provided for binding into the bottom weave.
  • the pile warp thread P2 is lifted in succession, to the following positions: middle - middle - middle - middle - middle - bottom.
