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.
  • 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 while avoiding the aforementioned disadvantages, is to provide a method and an apparatus, and with both a fabric, in the production of which there is no impairment of the highly sensitive warp threads even at high weft densities.
  • the solution according to the invention has the advantage that weft densities of 20 to over 150 weft / cm can be worked from highly sensitive yarns of the type mentioned, including the appropriate bonds, and thus the production of technical fabrics in warp and weft in a three-dimensional arrangement (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 is especially true in the case of highly sensitive materials for the warp threads, so that, as has been found, a decrease in strength due to damage to individual capillaries of the thread no longer occurs there. This leads to an optimal product, especially for multi-layer fabrics.
  • the blade segment holders 4-image 1- are screwed, which hold the blade segments 9-image 1- in the width of the goods edge.
  • the leaf segments which work directly to the right and left of the reed, take over after each weft entry the stop on the right and left goods edge, the warp threads of which are made of an insensitive material.
  • This device ensures that each weft thread, in the event that there is no regular leaf stop, is deposited about 1-3 cm in front of the edge of the goods.
  • the principle of 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 shaft changes are carried out successively only from top to bottom or only from bottom to top.
  • the number of shots to be fired at the edge of the goods at the same time by means of periodic sheet firing as a group depends on the construction of the binding and can be at least 2 and at most up to more than 10 shots.
  • the design features of the finished fabric which it possesses due to the fact that lateral edge zones were struck after each shot, but the middle area only after the entry of a respective group of wefts of a certain size, especially in the area of technical fabrics, their use was not affect.
  • the edge zones equipped with normal, less sensitive warp threads can also be cut off in full or in part.
