Definitions

  • the present invention relates to a method for producing woven, at least partially multi-layered, airbags, as well as a fabric, in particular for partially multi-layered airbags.
  • JP-2000 15372 discloses a method of making woven airbags in which the airbags are cut out of the airbag fabric with a cutting device.
  • Fabrics, especially for partially multi-layered airbags, are usually cut to size on cutting tables after weaving.
  • One-piece weave woven, partially multi-ply airbags are called “one-piece woven airbags" or "OPW” for short.
  • the position and the contour of the OPW in the fabric web coming from the weaving machine should be the specification for a cutting machine.
  • the cutting of the individual part or cut-to-size sets is as follows: From the customer specifications, the dimensioning of the individual parts is done manually or automatically, for example via a CAD program created a program sequence for example, a CNC-controlled cutting system that describes how the individual parts of the airbag fabric to be cut out. The cutting takes place independently of the condition of the tissue, i. The cutting element moves relative to a reference point of the cutting system, regardless of how and where the material to be cut of the plant actually exists.
  • the present invention has for its object to provide a method for producing woven, in particular at least partially multi-layered, airbags, as well as a tissue, wherein the disadvantages known from the prior art are avoided or at least greatly reduced.
  • This procedure has the great advantage that it is ensured by the introduced markers that the fixed points achieved in the tissue of reading devices are read by machine and always achieved safely in subsequent process steps.
  • this method which allows any desired position and frequency of markings, one is able to compensate for both contour and dimensional deviations in and between the individual located in the weaving web airbags when cutting and beyond safe points of subsequent process steps safely set, and this is independent of the fact that a textile lives and every airbag variant sets different requirements.
  • the method according to the invention is characterized by machine-readable markings for the recognition of specific tissue parts.
  • markings for example, single or multiple color, by structure, material or in any other way from the airbag fabric differing threads, so-called Kennfäden, woven during the weaving process.
  • These cords or markers allow in an advantageous manner over defined desired distances from each other and the specified target arrangement, based on an OPW, in conjunction with the respective actual distances and the actual arrangement, a conclusion about the shape and / or size and / or orientation and or distortion of the cut OPW or the OPW in the uncut airbag fabric, or provide information about the shape and / or size and / or orientation and / or distortion of the blank after the cutting process in the following steps.
  • suitable warp threads for machine-readable markings are already accommodated in the warp as identifiers.
  • wefts suitable for machine-readable markings are woven over at least part of the width of the fabric as passwords.
  • the cutting device is guided by the woven machine-readable markings.
  • the actual positions of these threads or markings are determined via a corresponding system and compared with the desired positions stored in a program sequence for cutting OPW or airbag parts and the differences for an automatic adaptation of the cutting program (eg Resizing) used.
  • the very personnel-intensive measurement of the OPW, uncut in the airbag fabric or during or after the cutting process, can be done automatically.
  • the distinguishing from the OPW or airbag material cues or markers can be detected via a detection system and the status of the OPW with respect to the shape and / or size and / or orientation and / or distortion, on the arrangement of the cords or markers are determined ,
  • the data obtained on the goods in each case allow conclusions about the current state of the OPW.
  • Fig. 1 schematically shows a tissue cutout with printed markings not falling under the claimed invention.
  • Fig. 2 schematically shows a tissue section with woven markings.
  • Fig. 1 shows an OPW fabric 1 with printed markings 2, which are matched to the woven contour 4.
  • Fig. 2 shows an OPW fabric 1 a in the opposite to the base material different yarns 2 a, before or during the weaving process, were introduced, which are matched to the woven contours 4 a.
  • the applied before, during or after the weaving process on the tissue or the woven contour of an OPW attached or incorporated markers, e.g. by imprint or characteristic threads, are used to adapt subsequent processes to the web contour or the tissue as reference points, in particular for the detection of woven contours of the OPW and the coordinated correction of the subsequent process steps.
