Definitions

  • the invention relates to a method for weaving a double-layer fabric and applications of the method, in particular for the production of airbag fabrics.
  • US-A-5 651 395 describes methods of making bags for Airbags, whereby double-layer fabrics are produced for this production. With such fabrics, two-layer areas can be separated from one differ. From the two-layer areas, each from a sub-and consist of an upper fabric, the inflatable interiors of the Sacks formed. In the single-layer areas are warp threads that are in the two-layer areas separated either in the lower or upper fabric through binding measures to a common Partial tissue crossed. From the single-ply areas, the two-ply completely enclose closed hems of the sacks produce.
  • the quality of the double-layer fabric for example for airbags - d. H. on the so-called loss of goods - high demands are made.
  • Fabrics must have the warp and weft threads even and relatively dense be arranged. The deviation from a specified air permeability the lower or upper fabric should be minimal.
  • the fabric layers must so be as tight as possible.
  • the threads used must withstand high loads in terms of tensile strength and elasticity can.
  • the double-layer fabric for airbags is a tailored product, namely a fabric that is made to an exact measure. On weaving machines, which are equipped in the usual way, the two-ply has unfavorable Effects on the loss of goods if custom goods are to be manufactured:
  • the object of the invention is to provide an improved method for weaving a To create double-layer fabric in which the disadvantageous wrinkling avoided or less. This object is achieved by the in claim 1 defined procedures solved.
  • the method for weaving a double-layer fabric serves in particular for the production of airbag fabrics. It comes with a weaving machine carried out between the sley and the merchandise tree Spreader arrangement which immediately after a stop edge (30) is arranged, a deflecting element for the fabric and a drive roller includes. With the drive roller and using suitable means the tissue produced is transported away from the stop edge in a manner that on the two layers of the fabric - on the lower fabric or Upper fabric - is applied with largely symmetrical forces. It will the fabric in the spreader assembly through a gap between two stationary surfaces pulled through against frictional resistance and stretched at the same time with lateral spreader bars perpendicular to the transport direction. With a rotatable pressure roller used in addition to the drive roller the fabric is driven, the pressure roller that the Deflecting element is in operative connection with the drive roller.
  • Fig. 1 shows schematically and only partially a weaving machine, at the a goods deduction with the appearance of adverse wrinkling connected is.
  • Warp threads 1 "are shown for an upper compartment as well Warp threads 2 "for a lower compartment and a sley 3 for attaching weft threads, not shown, with which together with the one hand Warp threads 1 "and on the other hand the warp threads 2" the upper fabric 1 and the Bottom fabric 2 are made. It also shows: one Stop edge 30; a rod spreader 4, which is shown in more detail in FIG. 2 is; a rod-shaped deflection element 5 'for the fabric layers 1 and 2; a Drive roller 6 and a pressure roller 7, not connected to the one depicted goods tree follows (goods tree 10 in FIG. 7).
  • the rod spreader 4 the cross section of which can be seen in FIG. 2, comprises a rotatable rod 41, which is driven by the fabric layer 1, and a bearing shell 42, which is composed of two parts 42a and 42b.
  • the warp threads 1 "and 2" integrated into the fabrics 1 and 2 are indicated by wavy lines 1 'and 2'.
  • the upper fabric 1 moves at a speed v 1
  • the lower fabric 2 at a speed v 2 .
  • the fabric 1 and 2 are pressed against the bearing shell 42 by the rod 41. Since frictional forces F act between the lower fabric 2 and the bearing shell 42 and since the rod 41 makes a rotational movement corresponding to the speed v 1 , v 1 is somewhat larger than v 2 : there is therefore a displacement between the two fabrics 1 and 2. This is unfavorable
  • the shift effect is most pronounced at the deflection points 421 and 422 (“stowage points”).
  • the deflecting element 5 ' also contributes to the displacement effect at a "s
  • Fig. 4 a deduction of goods in a weaving machine is shown, in which the method according to the invention is applied.
  • the fabric 1, 2 produced with the Drive roller 6 and using suitable means from the Stop edge 30 transported away in a way that on the two layers 1 and 2 of the tissue is applied with largely symmetrical forces.
  • These suitable means consist of a special spreader arrangement 4 and a deflection element 5 'designed as a pressure roller 5.
  • the Fabric 1, 2 is in the spreader assembly 4 through a gap 440 between two stationary surfaces against frictional resistance pulled through.
  • the gap 440 of the spreader assembly 4 lies between a rod 43 and a support shell 44, which is, for example, trough-shaped.
  • the Tissue 1, 2 is held down with the rod 43 and rounded Deflection edges 441 and 442 of the support shell 44 are pressed.
  • the support shell 44 has a concave shape in the effective area of the rod 43 and is of such a shape trained that their shape in a complementary manner to the shape of the Rod 43 including overlying fabric 1, 2 fits.
  • the convex formed deflection edges 441 and 442 form the entrance or Exit area of the gap 440 so that the tissue 1, 2 at the entrance and is transported horizontally at the exit.
  • the rod 43 is so strongly after pressed down that the between the upper fabric 1 and the rod 43 acting friction about the same as that between the lower tissues 2 and the support shell 44 is acting friction.
  • the lower fabric 2 must do not touch the concave central area of the support shell 44.
  • the pressure roller 5 is operatively connected to the drive roller 6:
  • the pressure roller 5 is arranged with respect to the drive roller 6 so that the fabric 1, 2 on the pressure roller 5 along this one Contact angle of at least 170 ° is in contact.
  • a torque is from the drive roller 6 to the pressure roller 5 over the in between lying tissue 1, 2 exercised. Because of this arrangement, the Pressure roller 5 from a drive point 51 with a tensile force on the Lower fabric 2 a; the drive roller 6 acts from a drive point 61 with a tensile force on the upper fabric 2.
  • the pressure roller 5 is with Advantage so strongly pressed against the drive roller 6 that the two mentioned tensile forces are largely the same.
  • the value of the The wrap angle on the pressure roller 5 is advantageously in the range between 170 ° and 190 °.
  • FIGS. 5 and 6 represent two variant forms of the spreader arrangement 4
  • the gap 440 is in each case by the Rod 43 and a profile rod 44 'with only one deflection edge 441' or a profile rod 44 "with deflection edge 441" is formed.
  • the rod too 43 set up so that its position is adjustable. The setting can be made in both the vertical and horizontal directions.
  • FIG. 7 is a partial illustration of the weaving machine from FIG. 4.
  • the spreader assembly 4 the fabric 1, 2 with lateral Spreader bars 45 extend transversely to the transport direction.
  • the warp threads 1 "and 2" are moved with shafts 8.
  • a double weave can be created that in the warp direction on the one hand laterally and on the other hand in periodic Spaces closed areas, so that from the product rectangular bags or hollow fabric sections, especially rectangular ones Airbags that can be produced. Folds as they are with the weaving machine of FIG. 1 7 do not arise with the weaving machine shown in FIG correct attitude - or are significantly weaker.
  • FIG. 8 shows a first product of the method according to the invention in schematic representation, from which rectangular sacks or Hollow tissue sections can be produced.
  • 9 shows a second product for the production of round sacks or hollow fabric sections.
  • the warp threads Use a jacquard machine and / or another Shed forming device moves.
