Definitions

  • the invention relates to a reed for weaving machines with mechanically driven weft insertion members, which consists of a plurality of individual, parallel and spaced from each other and in series anchored between a first reed bundle and a second reed bundle.
  • the invention relates to a rapier guide temporarily connected to the reed and finally to a guide element for the rapier.
  • a gripper for a weaving machine with weft insertion by alternately pushing back and forth sliding elements in the shed and with a gripper arranged at one end is known.
  • the gripper has a side wall on which at least one guide element is arranged, with which the gripper slides along the reed.
  • Such a guide element is mounted on the side wall of the hook in a tiltable manner transversely to the weft insertion direction. This has the advantage that, in the control phase of the gripper, the guide element can align itself with the fixed reed and contacts the largest possible sliding surface of the gripper with the reed. This ensures a smooth gripper run.
  • such a guide element does not prevent, for example, in a weaving machine in which the grippers are arranged at the end of a rigid or flexible support member and the grippers are loosely guided, for example, on a shelf of the loom arranged on the weaving machine, the grippers in the course of the weft insertion leave their predetermined leadership. This is particularly evident in the case of fast-running weaving machines when the rapier is lifted off the sole of the shop.
  • the object of the invention is therefore to develop a known reed for weaving machines with mechanically driven weft insertion elements in such a way that it is suitable for guiding any type of straight weft insertion elements with grippers over the weaving width and that it interacts with a gripper guide element Lift the gripper off excludes the store sole. Furthermore, the invention has for its object to provide a guide element which is suitable, in conjunction with the reed designed according to the invention, to act as a connecting link between the gripper and the reed.
  • the individual lamellae of a reed striking the weft thread on the fabric have at least one profiled section Have recess, which is preferably located below the weft stop line.
  • the individual recesses form a profiled channel in the reed.
  • the profile of the channel can have any geometric shape.
  • An advantageous embodiment can be, for example, a slot shape, a spherical shape or a dovetail shape. It is important in such a design that the stop-side opening of the recess in question is preferably provided below the weft thread stop line.
  • Such an embodiment has the advantage that the grippers or the organs carrying them experience additional guidance in the vertical and horizontal plane during their alternating movement in the shed.
  • the guide element is designed in such a way that, while maintaining the sliding guidance of the gripper on the reed, the guide element has at least one approach facing away from the side wall of the gripper.
  • the cross-section of the approach corresponds adequately to the cross-sectional shape of the lamella recesses.
  • the reed 1 designed according to the invention is connected to the reed 2 of a weaving machine, not shown.
  • the sheet bar 2 stands with a gem.
  • a T-shaped shop sole 5 is interchangeably provided on the sheet bar 2.
  • the reed consists of a plurality of lamellae 6, which are anchored at a distance from one another at their free ends 6a, 6b in a first or upper reed band 1a and a second or lower reed band 1b.
  • each of the slats 6, starting from a front stop side 6c is provided with at least one recess 6d having a specific profile shape.
  • the recess 6d is preferably introduced into the respective slat 6 below a slat region 6e which strikes the weft thread against a fabric edge.
  • the individual slats 6 are anchored in series one behind the other in the collar 1a and 1b in such a way that the recesses 6d are aligned with one another and form a channel over the width of the reed 1.
  • the side facing away from the stop side of the lamella 6 is curved. This ensures the stability of the reed 1.
  • Figure 2 shows the reed 1 designed according to the invention arranged in the leaf bar 2.
  • the sley 4 is located here in one of the stop edges 7 of the fabric 8 facing away position. In this position, the shed 11 formed from a plurality of upper and lower warp threads 9, 10 is opened.
  • the lower warp threads are supported here, for example, by the flat upper surface 5a of the shop sole 5 connected to the sheet bar 2.
  • the gripper 12 carrying the weft thread slides alternately in and out of the shed 11 on the lower warp threads 10 for the purpose of weft insertion.
  • the side wall 12a of the gripper 12 facing the reed 1 carries a guide element 13.
  • the guide element 13 forms an extension 13a, which has an adequate profile shape to the recess 6d in the lamella 6. This approach slides together with the gripper in the recesses 6d, which form a channel via the reed 1.
  • the gripper 12 with the guide element 13, in addition to the sliding guide known per se on the weft stop surface 6c of the slats 6, is additionally secured against being lifted off the soleplate 5a.
  • FIG. 3 shows a detail "Z" from FIG. 2.
  • the gripper 12 which is only partially shown, receives on its reed side wall 12a via a bore 12b, into which, for example, an elastic connecting element 14 can be inserted, the guide element 13 with its profiled attachment 13a via the countersunk hole 13e.
  • the guide element 13 is shown here in cross section. It is essential to the invention that the guide element 13 has at least one connecting surface 13b running parallel to the side wall 12a of the gripper 12, at least one first sliding surface 13c spaced at an acute angle from the connecting surface 13b and at least one sliding surface 13d starting from the first sliding surface 13c and having a profile contour merges into the pad 13b.
