Definitions

  • the thread separation group 6, which presents the warp threads KF to be drawn in to the pull-in needle 7, and the path of movement of the pull-in needle 7, which runs vertically to the plane of the stretched warp threads KF, determine a plane in the region of a support 10 forming part of the base frame, which supports the already mentioned upgrade side of the so-called disassembly side of the drawing machine.
  • the warp threads and the individual elements into which the warp threads are to be fed are fed in on the upgrade side, and the so-called dishes (strands, lamellae and sheets) with the drawn-in warp threads can be removed on the tear-down side.
  • the strands LI are lined up on rails 13 and manually or automatically shifted to a separation stage on them. Then the strands LI are individually brought into their retracted position and, after they have been drawn in, distributed to the corresponding mounting rails 14 on the dismantling side. The reed is also moved past the pull-in needle 7 step by step, the corresponding sheet gap being opened for the feed. After it has been drawn in, the sheet is also on the dismantling side. A part of the reed WB can be seen to the right of the mounting rails 14. This illustration is to be understood purely for illustrative purposes, since the reed is of course located on the upgrade page in the position of the frame 5 shown.
  • the heddle magazine shown in FIG. 3 can be used universally and is suitable for the storage of heddles with open and those with closed end loops.
  • Stranded wires with open end loops can be easily stored because they have hook-like end loops and can therefore be easily moved on the mounting rails if only the carriers holding the mounting rails lie in the area of the open part of the end loops, i.e. the mouth of the hook.
  • Stranded wires with closed end loops on the other hand, can only be moved on all-round free mounting rails, but this cannot be achieved with mounting rails with a length of more than half a meter.
  • terminals K 1 to K 6 The opening and closing of terminals K 1 to K 6 is controlled so that two adjacent terminals can never be open at the same time.
  • detectors 32 (FIGS. 7a, 7b) for the passage of strands are arranged in their immediate vicinity.
  • the detector 32 arranged on the first clamp K 1 detects the presence of this heald stack firmly on the first clamp and opens it.
  • the strand of strands can thus pass through the first clamp, comes into the effective range of the conveyor belt 29 equipped with the brushes 28 and is automatically pushed by it to the second clamp K 2 .
  • FIGS. 4 and 5 show the arrangement of the clamps and detectors in a side view and in a plan view of the head end of the stranded magazine carrying the separation station ST
  • FIGS. 6a to 6c show three views of a clamp
  • FIGS. 7a and 7b show two Views of a wire detector.
  • FIG. 6a shows a view of a clamp K n in the direction opposite to arrow IV in FIG. 3
  • FIG. 6b shows a view related to FIG. 6a from the left
  • FIG. 6c shows a view related to FIG. 6b from above .
  • the Clamp K n is designed like pliers and essentially consists of a pneumatic cylinder 33, a guide block 34 firmly connected to the pneumatic cylinder 33 and a pair of clamping jaws 35 and 36.
  • the guide 35 is provided with a fixing cone 39 which is encompassed in a semicircle by the clamping end of the pivoting lever 36.
  • the fixing cone 39 which is only provided on the first clamp K 1 , serves to engage in a corresponding bore in the heddle support rail 13, as a result of which the heddle support rails are additionally fixed at the end mentioned.
  • the guides 35 have an approximately trapezoidal cross-section, the oblique flanks serving to ensure that the heddle support rail 13 securely engages in the base offset in accordance with the support rail cross-section during the clamping process the guide 35 is inserted.
  • FIGS. 6a and 6b show two vertical bores 40 in the guide block 34; these are provided for receiving screws which are used to connect the terminal K n to the respective wire detector 32.
  • the position of the clamp K n shown in FIGS. 6a and 6b represents, with respect to the top and bottom, a clamp arranged on the lower profile rail 16 (FIGS. 3, 4).
  • the clamps K n are rotated accordingly by 180 °, so that the point of engagement of the pivot lever 36 in the slide 38 would be in the upper and the clamping end of the pivot lever 36 in the lower half of the figure.
  • FIG. 7a shows a side view of a heddle detector 32 seen in the longitudinal direction of an upper heddle support rail 13, in fact opposite to the transport direction A (FIG. 3);
  • FIG. 7b shows a top view of FIG. 7a.
  • the stranded detector 32 consists of a wing-like support part 41 bent over at one end and a sensor lever 42 pivotally fastened to the support part 41.
  • the support part 41 carries at one end a fastening part 43 provided for fastening to a clamp K n (bores 40) and at its other, bent end an inductive sensor 44.
  • the sensor lever 42 projects above the carrier part 41 at its front end and carries at this end a circular plate 45 protruding into the movement path of the strands.
