Definitions

  • the invention relates to an air jet loom with a jacquard frame according to the preamble of patent claim 1.
  • the jacquard scaffold sits vertically in the middle, exactly above the intended feed width, so that the harness threads are aligned symmetrically.
  • the present invention is therefore based on the object of further developing an air-jet weaving machine with jacquard of the type mentioned at the outset in such a way that gentle fabric removal is possible when higher weaving frequencies are reached.
  • the invention is characterized in that the elements on the weft side in the weft direction are arranged on the loom.
  • the fabric runs symmetrically over the spreading roller, which ensures gentle fabric removal, and when using heald frames for shed formation, the shafts are loaded symmetrically, which reduces the vibrations of the shafts at higher weaving frequencies.
  • the main nozzle holder is designed to be displaceable;
  • other elements are slidably formed on the weft side, such as. B. the scissors, the auxiliary bar apparatus and the thread clamps.
  • a synchronously driven control shaft extends over the entire machine width, because then all elements to be displaced on the weft side and on the catch side can be moved along this control shaft and are nevertheless always acted upon synchronously by this control shaft .
  • Figure 1 is shown schematically that a jacquard machine 1 is arranged centrally on a jacquard frame 2 or frame and with an air jet loom 48 cooperates.
  • the shorter reed 5 is now arranged exactly symmetrically and centrally under the jacquard machine 1, without therefore having to move the jacquard machine 1 on the jacquard frame 2.
  • the weft side 6 is now adjusted in the direction of the arrow 12 by the difference 13 between the longer reed 4 and to compensate for the shorter reed 5.
  • the elements arranged on the weft side must now be arranged on the air jet weaving machine 48 so as to be adjustable in the longitudinal direction, namely in the direction of the arrow 12 (and in the opposite direction).
  • FIGS. 2 to 4 show further details of the longitudinal adjustment.
  • FIG. 2 shows that a main nozzle 16 consists of a holder 17 in which one or more nozzle tubes 18 are arranged, which form the thread outlet openings 19 on their front side.
  • the cold 17 is in this case arranged in the arrow directions 12 so as to be longitudinally displaceable on the sheet bar 20.
  • the screws 23 each pass through elongated holes 22 arranged in the longitudinal direction in the holder 17, so that the entire holder 17 can be displaced on the sheet bar 20 in the region of the elongated hole 22.
  • FIG. 2 also shows that the weft threads 49 are fed to the main nozzle 16.
  • FIG. 3 shows further details of the synchronous drive of the individual elements.
  • control shaft 24 extends over the entire width of the air jet loom 48. This gives the essential advantage that all functional elements of the weft side 6 and the catching side 7 can be moved along this control shaft and are nevertheless always driven synchronously by this control shaft.
  • control shaft 24 is rotatably supported on bearings 27 on the frame 50 of the air jet weaving machine via bearings 25, 26.
  • the rotary drive of the control shaft 24 takes place here via a gear transmission 31, 32.
  • a displaceable scissor drive is shown as an example in FIG. 3; it goes without saying that the other functional elements on the weft side are controlled by adjusting elements having the same effect and are therefore displaceable.
  • the eccentric 28 provided for driving the scissors 36 shown in FIG. 4 is connected in a rotationally fixed manner to a bushing 29, which in turn can be displaced in the longitudinal direction on the control shaft 24 via a feather key 30.
  • a bushing 29 which in turn can be displaced in the longitudinal direction on the control shaft 24 via a feather key 30.
  • Figure 4 further details of the drive of the scissors 36 are shown.
  • control shaft 24 is again rotatably mounted in the bearing block 27, whereby it can be seen that the eccentric 28 acts on a pivoting lever 37 which is pivotably mounted on the bearing block 27 on one side in the bearing 38 and acts spring-loaded on the scissors 36 via the spring 39.
  • one cutting edge 40 is pivotally driven, while the other cutting edge 40 is fixedly attached to the bearing block 27.
  • the entire scissors 36 can thus be displaced along the control shaft 24 perpendicular to the plane of the drawing in FIG.
  • the warp threads 41 are guided through the heald eyes 43 of the healds 42 which are parallel and at a mutual distance from one another, the weft insertion system, which consists of a profile reed 44, the relay nozzle, being arranged between the upper and the lower warp thread 41 45 are assigned, wherein the parts mentioned are mounted on a sheet bar 46, which in turn is attached to a sheet support 47.
  • the finished fabric 34 is drawn off over the spreading roller 33 in the direction of arrow 35.
  • the weft side according to FIG. 1 is arranged displaceably in the arrow directions 12, so that a symmetrical arrangement of the feed width in jacquard machines is thus ensured. This ensures that the fabric runs symmetrically over the spreading roller 33, which ensures gentle fabric removal.
