Definitions
- the present invention relates to a method for weaving multi-layer fabrics, at least in certain areas, in particular in one-piece woven air bags (OPW) with an upper fabric layer and a lower fabric layer, which are woven into a single layer in an edge region.
- OGW woven air bags
- contour-related woven multi-layer fabrics for example in a piece of woven air bags, so-called one-piece woven air bags (OPW)
- OHPW one-piece woven air bags
- several areas with different numbers of fabric layers can be used during training, for example with woven spacers and / or when using Different materials and / or fineness of material, due to which different tissue density or different cover factor occur in the individual layers of the adjacent areas of folds. This happens due to the different ratios of mass to unit area, which increases or decreases per layer if the existing mass of yarn material is divided into more or fewer layers than before or if a coarser yarn, i.e. the same thread density. a yarn with more mass is used.
- Another disadvantage is that the adhesion of a possibly laminated film can be impaired by the non-flat surface of a wrinkled area and the application of a possibly provided coating in the corresponding areas may deviate from the specification and / or the adhesion of the coating could be impaired. This would also mean that the technical requirements would not be met and the product, like the products with the deficiencies described above, would have to be discarded as a committee.
- the object is achieved with a method according to claim 1.
- folds which give rise to countless defects in the end product are advantageously avoided. Differences in tissue density are compensated for by carrying out the method according to the invention. Uniform incorporation is achieved throughout the airbag and uniform shrinkage is triggered. Tissue strengths are not reduced by pinched folds, so that the specification values can be maintained as a result. The safe function is guaranteed on the tissue side. Because of the smooth, wrinkle-free surface of the OPW that can be achieved using the method according to the invention, a uniform coating over all areas of the airbag or OPW is possible. A film can be laminated evenly over the entire airbag, which ensures an even tightness of the fabric of the OPW. By means of the method according to the invention, the rejection of air bags due to folds in the end product can be avoided in the weaving process at an early stage of the manufacturing process.
- a 1/1 plain weave is woven in a two-ply woven fabric (12) in mixed rep and a four-ply woven fabric (14).
- weave weave combinations also mean combinations of other weaves with plain weaves.
- Figure 1 shows the result of a weaving process according to the prior art
- Figure 2 also shows two areas of an OPW, this time with binding combinations that result after using the inventive method.
- FIG. 1 shows the transition from a two-layer area 2 to a four-layer area 4 of an airbag woven according to a method known from the prior art.
- a plain weave L 1/1 is used in both areas 2 and 4.
- FIG. 2 shows the transition between a layer of a two-layer area and a layer of a four-layer area of an airbag produced by the method according to the invention.
- a weave combination of plain weave L 1/1 and grosgrain weave RL 1/1 is double-threaded and in the four-ply area 14 shown in FIG. 2 on the right-hand side a plain weave L 1/1 is used.
- the fabric shown in FIG. 2, produced when the method according to the invention is carried out, has a uniform fabric density in which, based on the procedure according to the invention, the fabric density of the two-layer region 12 is reduced and thus the fabric density of a layer of the four-layer region 14 is adjusted.
