Definitions

  • the present invention relates to a clamping device for a flat thread layer with a clamping rail running transversely to the threads of the thread layer.
  • Such clamping devices are used for example in warp threading machines and in warp knitting machines for clamping the warp threads. They usually consist of a clamping rail extending over the entire width of the chain and of a rod-shaped clamping comb held in or on the clamping rail, which is pressed into the clamping rail from above and then locked with it. When disassembling after the knotting operation, the clamping rail or comb must be pulled out to the side after loosening the clamping.
  • this clamping device is to be used when changing the warp on the weaving machine, then the lateral removal of the clamping comb and / or the clamping rail is very cumbersome for reasons of space alone.
  • the clamping rail would also have to be provided in a suitable manner at the clamping point, for which purpose either a lateral insertion before clamping or a permanent arrangement on the weaving machine would be required.
  • the former has the disadvantages already mentioned with the clamping comb and the permanent arrangement on the weaving machine would lead to intolerable contamination and dusting of the clamping rail.
  • the constant arrangement of the clamping rail on the weaving machine would not incur significant additional costs.
  • a clamping device for a flat thread layer is known with a clamping rail running transversely to the threads of the thread layer.
  • the clamping rail runs transversely to the threads of the thread layer on one side of the thread layer.
  • a cylindrical clamping rod on the other side of the thread layer is pressed against the thread layer and the clamping rail so that the thread layer partially surrounds the clamping rod and is clamped between clamping jaws in the clamping rail and the clamping rod. It is disadvantageous that here too the thread layer has to be inserted between the clamping rail and the clamping rod, or that the clamping rod has to be extended laterally.
  • the invention is now to provide a clamping device of the type mentioned, the handling of which is considerably simpler and also more automation-friendly than in the known devices mentioned.
  • the clamping member consists of a plurality of clamping elements arranged next to one another, one between an immersion position and a clamping position in or for the Thread layer pivotally adjustable bow or wing-like clamping part.
  • the invention thus proposes a one-sided clamping device, so to speak, that is one in which only one side of the thread layer has to be accessible.
  • This one-sided clamping device contains, on the one hand, a fixed clamping rail and, on the other hand, clamping elements mounted on it, which are adjustable between two pivot positions.
  • the clamping elements can dip into the thread layer from one side. If they are pivoted into the clamping position after passing through the thread layer, then they grip around the thread layer from the other side and, together with the clamping rail, form a clamping gap which is closed when the clamping elements move back to the clamping rail.
  • the invention further relates to the use of said clamping device for clamping a warp thread layer.
  • FIG. 1 and 2 show a front and a side view of a clamping device according to the invention, which according to the illustration is formed by a clamping rail 1 and by a clamping element Kl to Kn arranged next to one another Clamping element exists.
  • the clamping device is used to clamp flat thread layers FS, in particular warp threads and the like.
  • the individual threads forming the thread layer FS run perpendicular to the drawing plane in FIG. 1 and horizontally, that is to say transversely across the drawing sheet, in FIG. 2, and they are generally arranged closely next to one another.
  • the clamping device according to the invention is a "one-sided", in which the material to be clamped, that is to say the thread layer FS, only needs to be accessible on one side.
  • This page is based on FIGS. 1 and 2 the upper side of the thread layer FS; However, depending on the spatial conditions, it can also be the lower side or, in the case of a vertical layer of thread, the left or the right or the rear or the front side.
  • the clamping device is positioned on this one side of the thread layer FS, as a result of which the position of the clamping rail 1 is fixed on this one side. Now the clamping elements movable relative to the clamping rail 1 have to be brought to the other side of the thread layer FS to form a clamping gap and finally the clamping gap has to be closed.
  • the clamping elements Kl to Kn essentially consist of a bolt 2 which is mounted on the clamping rail 1 in a stroke-displaceable manner and which protrudes from the clamping rail 1 at one end and a wing-like one at this end Clamping part 3 carries.
  • This is formed by a relatively thin lamella, tapered towards its free end, both in length and in thickness, which has approximately the shape of an isosceles triangle carried by the bolt 2 at its base. The length of this base is greater than the distance between adjacent bolts 2.
  • the clamping parts 3 are aligned such that they run parallel to the threads forming the thread layer FS; they are thus rotated by 90 ° with respect to the position shown in FIGS. 1 and 2. In this position, the clamping parts 3 can easily penetrate the thread layer FS. They are then pivoted back by 90 ° and assume the position shown in the figures, in which they form a coherent clamping member and, together with the clamping rail 1, limit a clamping gap that extends over the width of the thread layer FS.
  • the individual bolts 2 are firmly connected in the area of their central part to a support ring or a support slat 4, with which they are supported on a holding member 5 carried by the clamping rail 1.
  • the cross-section of the clamping rail 1 has a corresponding shape, for example a C-shaped profile with a bottom 6, a top wall 7 and a rear wall 8. Between the support rings 4 and the top wall 7 act compression springs 9 which press the support ring 4 against the holding member 5 and thus the clamping elements Kl to Kn down.
  • FIG. 3 which shows a detailed view in the direction of arrow III of FIG. 1, the bolts 2 and the clamping part 3 are rotated or pivoted by a rod-like slide 10 that extends over the length of the clamping rail 1 , which is articulated with the adjustment arms 11 attached to the individual bolts 2.
  • the adjustment path of the slide 10 is limited by stop elements 12 arranged in the clamping rail 1 in such a way that the clamping parts 3 are pivoted parallel and perpendicular to the threads between the two positions.
  • the clamping position of the clamping elements Kl to Kn and the adjustment arms 11 is full and the immersion position is shown in dashed lines.
  • the clamping parts 3 Since, as already mentioned, the length of the clamping parts 3 at their base is greater than the pitch of the bolts 2, the clamping parts 3 overlap one another by a few millimeters in their clamping position. So that the clamping member formed by the clamping parts 3 of the individual elements Kl to Kn has the smoothest possible surface without laterally protruding edges or corners, the clamping parts are correspondingly graduated in their overlapping area.
  • the gradations labeled A are particularly evident from FIG. 3.
  • the holding member 5 is formed by two parallel pairs of racks arranged on both sides along the bolts 2 and each containing a first and a second rack 13 or 14.
  • the first racks 13, which serve as a support for the support rings 4 and thus for the clamping elements Kl or Kn, are flat on their support edge for the support rings 4 and have teeth on their lower edge.
  • they are arranged in the clamping rail 1 so that they can only perform a vertical movement.
  • the second racks 14 also have a straight edge and a toothed edge.
  • the straight edge serves as a contact surface on the bottom 6 of the clamping rail 1, and the toothing on the other edge is in engagement with the toothing of the first toothed racks 13.
  • the second toothed racks 14 are arranged in the clamping rail 1 such that they can only carry out a horizontal adjustment movement in the longitudinal direction of the clamping rail 1. This adjustment is carried out by suitable means, for example by a screw 15 acting between the clamping rail 1 and the second toothed racks 14 (FIG. 1) or by an eccentric, a toggle lever, by hydraulic means or by compressed air.
  • the clamping rail 1 is provided on its supporting surface for the thread layer FS which forms the clamping gap with an elastic support 16 made of a suitable material, for example rubber.
  • an elastic support 16 made of a suitable material, for example rubber.
  • a thread deflection can take place at the clamping point, for which purpose the clamping rail 1 can have a groove 17 along the clamping line (FIG. 2).
  • the pad 16 could be omitted.
  • a another variant would be to make this groove wider and deeper and to provide it with an elastic insert.
  • the described one-sided clamping device can be used especially in the so-called warp preparation, that is when pulling in and tying in warps, and is superior to the conventional two-sided clamping devices, especially when space is limited, such as when used on the weaving machine.
