Definitions

  • the invention relates to an air jet loom with a jacquard machine arranged on a jacquard frame.
  • the jacquard machine sits vertically in the middle, exactly above the intended feed width of the reed, so that there is a symmetrical alignment of the harness cords.
  • the invention is based on the object, in an air jet weaving machine that works together with a jacquard machine and the reed is centered on the jacquard machine, controllable functional elements of the The weft side and the catch side of the reed, which has a certain feed width, to be designed to be traceable and at the same time to maintain the time setting of the controllable functional elements within a weaving cycle.
  • the object is solved by the features of claim 1.
  • the advantage is that the fabric runs symmetrically over the spreading roller, which ensures gentle fabric removal. It is also advantageous that when using heald frames for shed formation the shafts are loaded symmetrically, whereby the vibrations of the shafts are reduced at higher weaving frequencies.
  • a synchronously driven control shaft extends over the entire machine width, and along this control shaft all controllable functional elements to be moved can be tracked on the weft side and on the catch side of the feed width and are always acted upon synchronously by this control shaft.
  • the main advantage here is that the time setting of the controllable functional elements is retained within a weaving cycle.
  • the control shaft did not extend over the entire machine width in the previously known machines. It was therefore relatively difficult to synchronize the various functional elements on an air-jet weaving machine connected to a jacquard machine.
  • FIG. 1 shows schematically that a jacquard machine 1 is arranged centrally on a jacquard frame 2 and interacts with an air jet weaving machine 48.
  • the shorter reed 5 is now arranged exactly symmetrically and centrally under the jacquard machine 1 without having to move the jacquard machine 1 on the jacquard frame 2.
  • the weft side 6 is now additionally tracked in the direction of the arrow 12 in order to compensate for the difference 13 between the longer reed 4 and the shorter reed 5.
  • the functional elements arranged and controllable on the weft side 6 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 have a thread outlet opening 19 on their front side.
  • the holder 17 is arranged in the arrow directions 12 to be longitudinally displaceable on the sheet bar 46.
  • holes 21 are provided in the sheet bar 46, into which corresponding screws 23 can be screwed.
  • 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 moved in the region of the elongated hole 22 on the sheet bar 46.
  • FIG. 2 also shows that the weft threads 49 are fed to the main nozzle 16 will.
  • Figure 3 shows details of the synchronous drive of the individual elements.
  • control shaft 24 extends over the entire width of the air jet loom 48. This has the essential advantage that all controllable functional elements of the weft side 6 and the catching side 7 can be moved along this control shaft and are always driven synchronously by this control shaft.
  • control shaft 24 is rotatably mounted on bearings 25 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. It goes without saying that the other controllable functional elements on the weft side are controlled by elements having the same effect and are displaceable.
  • the eccentric 28 provided for driving the scissors 36 shown in FIG. 4 is connected in a rotationally fixed manner to a bush 29, which in turn can be displaced in the longitudinal direction on the control shaft 24 via a feather key 30.
  • control shaft 24 is rotatably mounted, wherein it can be seen that the eccentric 28 acts on a pivotally mounted on one side in the bearing 38 on the bearing block 27 pivot lever 37 which acts spring-loaded on the spring 39 non-positively on the scissors 36.
  • one cutting edge 40 is pivotally driven, while the other Cutting edge 40 is firmly attached to the bearing block 27.
  • the entire scissors 26 can thus be displaced along the control shaft 24 perpendicular to the plane of FIG. 4.
  • the warp threads 41 are guided through the heddle eyes 43 of the strands 42 arranged in parallel and spaced apart from one another, the weft insertion system being arranged between the upper and the lower warp thread 41, which system consists of the reed 4 with a weft insertion channel 44, which are associated with relay nozzles 45, and the main nozzle 16, the parts mentioned being mounted on the sheet bar 46, which in turn is fastened on a sheet support 47.
  • the finished fabric 34 is drawn off over the spreading roller 33 in the direction of arrow 35.
  • weft side 6 according to FIG. 1 is arranged to be displaceable in the direction of the arrows 12, so that a symmetrical alignment of the feed width in air jet looms which are connected to a jacquard machine is ensured. This ensures that the fabric runs symmetrically over the spreading roller 33, which ensures gentle fabric removal.
  • heald frames are loaded symmetrically, as a result of which higher weave frequencies can be achieved and shaft vibrations are avoided.
