Definitions

  • the invention relates to a method and a device for producing fabrics, in particular multi-layer fabrics, by means of a weaving machine, made entirely or overweight from highly sensitive technical fibers, such as carbon fibers, glass fibers or the like, and also a fabric made therefrom in its structure.
  • GB-PS 20 66 308 three-dimensional fabrics are known, in which carbon fibers or glass fibers are used. It is also known to provide a movement sequence for carbon fibers which avoids sudden stresses in order to take account of the extreme brittleness, which is caused by their temperature coefficient close to zero.
  • EP 00 56 351 Also known from EP 00 56 351 is a flat fabric, which consists of high-strength material, such as. B. Metal, carbon fibers, aramids or mixtures thereof etc. This flat fabric is brought into a certain shape.
  • the object of the invention is to create a method and an apparatus and with both a fabric while avoiding the aforementioned disadvantages, the manufacture of which does not impair the highly sensitive warp threads even at high weft densities.
  • the solution according to the invention has the advantage that high-sensitivity yarns of the type mentioned can be used with weft densities of 20 to over 150 wefts / cm, including the use of appropriate bindings, and thus the manufacture of technical fabrics in warp and weft, which are set very densely in a three-dimensional arrangement ⁇ tion (multi-layer fabric) is made possible. Even with a correspondingly high number of wefts, the friction of the leaf bars on the warp threads can be reduced so considerably that damage to the fabric is avoided. This applies in particular to highly sensitive materials for the warp threads, so that, as has been found, a reduction in strength due to damage to individual copules of the thread no longer occurs there. This leads to an optimal product, especially for multi-layer fabrics.
  • FIG. 1 the schematic structure of a loom with the inventive internals (in a clear representation)
  • FIG. 2 shows a detail of a weaving machine, in which the positioning and locking of the weaving reed holder is shown schematically
  • FIG. 3 shows a detail in the area of the limit switch control of a weaving machine according to FIG. 1.
  • This device ensures that each weft thread, in the event that there is no regular leaf stop, approx. Is placed 1-3 cm before the edge of the goods.
  • binding constructions can have several
  • Shots are entered which, as a shot group, are struck together at the edge of the goods with a blade stop after the couplings have been closed.
  • the principle of the periodic leaf stroke is to be matched to certain binding constructions.
  • this principle is suitable for the production of multi-layer fabrics which are constructed in such a way that periodically several shank changes take place successively only from top to bottom or only from bottom to top.
  • REPLACEMENT LEAF The goal of the greatest possible protection of the warp material during weaving is achieved the less the number of sheet stops in relation to the number of wefts entered.
  • the number of shots to be fired at the edge of the goods at the same time by means of periodic sheet firing depends on the construction of the binding and can be at least 2 and at most up to more than 10 shots.
  • the leaf stop must follow to form the shed with intersecting warp threads.
  • the design features of the finished fabric which it possesses, are due to the fact that lateral edge zones were struck after each shot, but the middle area was only struck after a shot group of a certain size had been entered, particularly in the area of the technical fabrics, the use of which does not interfere.
  • the marginal zones equipped with normal, low-warp threads can also be used in full or in part

Abstract

Procédé pour produire sur un métier mécanique des tissus, en particulier des tissus à couches multiples, dans lequel, afin d'assurer l'introduction extrêmement soignée de la trame même à un duitage élevé, ces derniers sont supérieurs à 20 trames/cm, les trames individuelles ne sont pas d'abord soumis à un battage de la duite, cette opération étant effectuée seulement après introduction d'une série complète de trames composée de plusieurs trames d'un nombre prédéterminé.
