Definitions

  • the present invention relates to a clamping device for a flat thread layer, with a fixed clamping rail and with a clamping member which is adjustable relative to the latter.
  • 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 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, as is the case, for example, in the US-A -3 741 836. When disassembling after tying, the clamping rail or comb must be pulled out to the side after releasing the clamping.
  • clamping device If this clamping device is to be used on the weaving machine when changing the warp, 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 either a lateral insertion before clamping or a constant 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. In addition, the constant arrangement of the clamping rail on the weaving machine would not incur significant additional costs.
  • 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 contains a clamping comb which can be immersed in the thread layer and has clamping lamellae which have a clamping edge assigned to the clamping rail, that a reed comb which is immersed in the thread layer is provided, and in that the reed comb and the clamping comb are longitudinally adjustable relative to one another, in which the adjustment path is a multiple of the division of the slats of one of the combs.
  • 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, the clamping comb, which is adjustable relative to this and can be immersed in the thread layer.
  • a preferred embodiment of the clamping device according to the invention is characterized in that the clamping comb is fixed and the reed comb is longitudinally adjustable, and that the adjustment path of the latter is more than twice the division of the clamping lamellae.
  • a clamping gap is formed between the clamping lamellae and the clamping rail.
  • the clamping comb is immersed in the thread layer, the threads of the thread layer oriented parallel to the clamping lamellae lie on the clamping rail.
  • the reed comb which is also immersed in the thread layer, is shifted in the longitudinal direction of the clamping comb by about 10 to 20 millimeters.
  • the threads on the clamping lamellae are deflected and laterally into the drawn between each clamping lamella and the clamping rail formed clamping gap. Then the actual clamping takes place by closing the clamping gap.
  • the clamping device according to the invention can be mounted on a robot-like, machine-drivable and controllable carrier which has the drive means required for the movements mentioned.
  • the invention further relates to the use of said clamping device for clamping a warp thread layer.
  • the clamping device consists of a U-shaped profile carrier 1; from a clamping comb 3 fastened in this via a holder 2, which is formed by clamping lamellae 4 arranged on the holder 2; from a vertically adjustable clamping rail 5, which is provided on its edge facing the clamping plates 4 with a support 6 made of an elastic material, for example rubber; from an adjustment mechanism shown in FIG. 3 for the clamping rail 5; from this adjustment mechanism and the clamping rail 5 bearing guide 7; and from a reed comb 8 which is arranged on the outside of the profiled beam 1 and is displaceable in its longitudinal direction.
  • the clamping lamellae 4 have an approximately L-shaped shape and are cantilevered towards the clamping rail 5 from their foot part fastened on the holder 2. In the area of the clamping rail 5, they are provided with a gradation, one edge 9 of which runs parallel to the warp thread layer KS and acts as a clamping edge. Between the clamping edges 9 of the individual clamping lamellae 4 and the clamping rail 5, a clamping gap is formed, which can be closed or opened away from the clamping edges 9 by adjusting the clamping rail 5 in the vertical direction.
  • the reed comb 8 the adjustment mechanism of which is not shown, is designed such that the tips of its teeth protrude beyond the profile carrier 1 and the clamping edges 9. If the clamping device is immersed in the warp thread layer KS as in FIG. 1, then the warp threads lie against the end edges of the side faces of the profile carrier 1 and run from the tooth gaps of the clamping comb 3 through the open clamping gap between the clamping rail 5 and the clamping edges 9 of the Clamping lamella 4 to the tooth gaps of the reed comb 8.
  • the pitch of the teeth of the reed comb 8 is chosen to be somewhat smaller than that of the clamp lamella 4 of the clamp comb 3, but it is variable within wide limits.
  • FIGS. 4a and 4b The function of the reed comb 8 can be seen from FIGS. 4a and 4b, with FIG. 4a immediately showing the starting position after immersion in the warp thread layer KS and FIG. 4b the clamping position before and during clamping.
  • the reed comb 8 is displaced in the longitudinal direction of the clamping comb 3 by a certain distance, the length of which is a multiple of the division of the clamping lamellae 4.
  • the pitch of the clamping lamella 4 is approximately 2.5 mm and the adjustment path of the reed comb is approximately 17 mm. The latter is, however, variable within wide limits.
  • the clamping rail 5 is provided with a toothing on its longitudinal edge facing away from the clamping lamellae 4 and is in engagement with a toothed rail 10 which is fastened to a holding block 11 which is guided so as to be longitudinally displaceable in the profile carrier 1.
  • the profile carrier 1 is closed at its end faces by holding plates 12 (these holding plates 12 are omitted in FIG. 1 for the sake of clarity).
  • a spindle 13 is mounted, during the rotation of which the holding block 11 and thus the toothed rail 10 fastened thereon are displaced in the profiled support 1.
  • the tooth splint 10 and the clamping rail 5 slide with their side surface facing the viewer in FIG.
  • the holding block 11 with the toothed rail 10 is pushed in the direction of arrow A to the left and to release the clamping in the opposite direction (arrow B) to the right. So that the clamping rail 5 is safely moved back into the starting position shown in FIGS. 1 and 3, in which the clamping gap is open, 10 guide rails 15 are fastened in grooves of the toothed rail, which protrude beyond the toothed rails 10 and in corresponding grooves 16 of the clamping rail 5 are guided like a sliding block.
  • other means such as springs or the like could also be used for this function.
  • the described one-sided clamping device can be used particularly in the so-called warp preparation, that is when pulling in and tying in warps, and is particularly evident in the conventional two-sided clamping devices cramped space conditions, such as are present when used on the weaving machine.

Abstract

Un dispositif de pincement comprend un rail fixe de pincement (5), un peigne de pincement ajustable par rapport au rail pouvant s'enfoncer dans la couche de fils (KS) et pourvu de lamelles de pincement (4) ayant un bord de pincement (9) associé au rail de pincement (5), ainsi qu'un peigne miseur (8) ajustable dans le sens de la longueur du peigne de pincement, pouvant s'enfoncer dans la couche de fils (KS) et dont la course de reglage est égale à un multiple de l'écartement entre les lamelles de pincement (4). On utilise ce dispositif pour pincer une couche de fils de chaîne. Premièrement, on positionne le dispositif de pincement d'un côté de la couche de fils de chaîne, puis on enfonce le dispositif de pincement avec la fente de pincement ouverte dans la couche de fils, puis on ajuste le peigne miseur dans le sens de la longueur du peigne de pincement, et finalement on ferme la fente de pincement.
