Embodiment Construction

[0011] The method of the invention will now be described by way of example with reference to the accompanying drawings.

[0012] Reference is now made to the sole accompanying drawing, which schematically shows the arrangement of the loom seen from the side. Warp beams 8 and 10 weaving positions provide warp tape 9 . In the area of ​​the harness packet 5 of the jacquard machine 7 (shown in fixed format), the reciprocating movement of the individual warp threads forms the rear shed 6 and the weaving shed 3 . In the region of the left-hand end of the shed 3 , a reed 4 can be seen from which the single- and / or multi-layer fabric 2 is wound up by the product winding drum 1 .

[0013] The use of two or more warp beams in interlacing single-layer and / or multi-layer fabrics according to the invention also enables considerable cost savings, since the frequency and time required to change warp threads is reduced by using multiple warp beams.

Abstract

The invention relates to a method for weaving single-layered and / or multi-layered woven fabric, especially airbag fabric. The inventive method is characterised in that warp threads delivered by at least two warp beams (8, 10) are interwoven.

Description

technical field [0001] The present invention relates to a method for weaving fabrics, more particularly airbag fabrics. Background technique [0002] In traditional fabric weaving techniques, as the weave varies, loose warp threads (warpthreads) exhibit differences in how they are inserted as they are worked. These loose threads are detrimental to the breathability of the fabric and its appearance. In addition, techniques are known for weaving double layer fabrics from warp strips provided by only a single warp beam, where tension between the upper and lower fabrics can manifest due to differences in shed geometry. There is a disadvantage that they can exhibit differences in physical properties between the upper and lower fabrics. In constructing fabrics, especially in the case of airbags, these differences between the upper and lower fabrics can become conceivable critical factors, in other words, in such airbags, the safety factor needs to have the maximum in terms of re...
