Definitions

  • a method of weaving fabrics having partially single-ply and partially double-ply regions in particular airbag airbag fabrics, in which warp yarns supplied by at least two warp beams are interwoven.
  • the GB-A-151 208 (Holt ) describes a method for producing quilts, filled comforters and the like, with woven figures or patterns in which floating wefts are simply cut off, ie the production of textiles in which warp threads supplied by two warp beams are interwoven.
  • the US-A-6 098 670 (Baumann ) describes a device for providing a uniform tension on the warp threads in a loom.
  • the device described there is constructed completely independently and operates completely independently of the presence of one or more warp beams or a single or multi-layered fabric.
  • the BE-A-1 010 848 (Picanol ) describes a weaving machine with two movable loom parts 1 and 2 and two movable warp beams for producing, inter alia, fantasy weaving, being emphasized in the description as an advantage that supplied by the two warp beams 11 and 12 warp threads to create a phantasy effect under different voltages to be woven.
  • the US-A-2,785,705 (Neisler ) describes a method for producing inflatable air mattresses from two different fabric layers, which have different numbers of weft threads per unit length in the untensioned state.
  • the warp threads for the two fabric layers are supplied by two different warp beams.
  • the result, the inflatable air mattress is intended to have two layers of fabric of different lengths, the longer, deformed fabric layer being stretched during inflation.
  • a method according to the preamble of claim 1 is made DE-A-4 226 954 known.
  • the conventional methods are also to be criticized for other reasons.
  • the sizing process by the high thread occupancy on the warp beam complete sheathing of each thread with sizing can not be guaranteed.
  • the sizing is applied to the warp to make the warp in the sizing process more resistant to the weaving process. Accordingly, with incomplete sheathing of the thread with sizing, there are enormous losses in quality due to errors caused thereby, such as capillary breaks, suspended lint nests, yarn breakages. These errors could be avoided with sufficient and evenly applied size. It may also occur in the sizing process that occur due to the high thread occupancy per warp beam bonds of several threads over a larger warp. These bonds lead in the subsequent weaving to the aforementioned quality losses.
  • the thread density is very high, especially in the production of two- or multi-ply fabrics from only one warp beam. Even under the condition of a theoretically optimal coating, the tightness in the back compartment can lead to the aforementioned weakening of the weave and quality.
  • the invention has for its object to provide a method for weaving fabrics, in particular, special of airbag fabrics, in which the known from the prior art disadvantages are avoided or at least greatly reduced.
  • the object is achieved with a method according to claim 1. If the total amount of warp yarn required for a fabric is distributed on at least two warp beams, much better sized warp yarn material can be used than in conventional processes.
  • a complete sheathing of the individual threads during sizing can take place at a quasi-warp spacing due to the reduced overall warp count per warp beam. Due to the reduced thread occupancy per warp beam possible by the method according to the invention, the risk of sticking individual warp threads is also reduced to a minimum, with both bonded warp threads and fluffy warp threads (broken capillaries due to insufficient sizing coats) being virtually avoided. The error rate during weaving can be drastically reduced.
  • the method according to the invention has further advantages, in particular if in multilayer fabrics, for example two-ply fabrics, each fabric layer can be produced separately with a warp thread of its own warp beam. As a result, a voltage equalization across the fabric width is achieved, which is comparable to the production of commercially available single-layer flat fabrics.
  • the method according to the invention makes it possible to achieve the required, very high fabric quality and to achieve virtually identical technical values in the individual fabric layers.
  • the described method of tension differences in the transition from single-layer P3 / 3 range are limited to a two-ply weave to a minimum.
  • the warp beams are independently controlled on the voltage side. This leads to a further increase in the homogenization of the tissue, especially in the case of two-layered fabrics.
  • the warp beams are equipped with different warp thread materials. If such a fabric is to be used, for example, for a side airbag in a passenger car, a warp thread material can be selected for the position of the fabric facing the passenger in the installed state in the passenger compartment, which results in an airbag surface that protects the passenger's head.
  • the pointing to the other window position of the fabric may contain a warp thread material which is particularly resistant to broken glass or the like.
  • warp threads of the two layers materials of different quality and price range said on the "Headerside” to protect the passenger higher value, or particularly appropriate (possibly finer) materials are used, whereas on the “window side” rough cheaper materials are used.
  • This can also reduce the production costs.
  • warp threads of different strength, texture, elasticity, fineness or material quality can be used in the two or more layers. It is also the use of elastic warp threads on a warp beam and inelastic warp threads on another warp beam conceivable. The advantages of this procedure are very numerous.
  • the figure shows a very schematic representation of an arrangement of a weaving machine from the side.
  • Kettfadenscharen 9 are supplied to the weaving, wherein in the area of a harness package 5 a (stylized illustrated) Jacquard machine 7 due to the up and down movements of the individual warp threads the rear compartment 6 and the shed 3 are formed. In the region of the left end of the shed 3, the reed 4 can be seen. From here one and / or multi-ply fabric 2 is wound up by a take-off roll 1.
  • the use according to the invention of two or more warp beams in the interweaving of one and / or multi-ply fabrics additionally provides a considerable cost advantage.
  • the use of several warp beams reduces the warp frequency and also the set-up times.
