  • Patent number: 6910508
    Abstract: A method for weaving a double layer cloth (1, 2) for use in the manufacture of airbag cloths. It is carried out using a weaving machine which includes, between the weaving sley (3) and the cloth beam (10), a temple arrangement (4) which is arranged directly after a beat-up edge (30), a deflection element (5?) for the cloth (1, 2) and a drive roller (6). The produced cloth is transported away from the beat-up edge with the drive roller and using suitable means in such a manner that both layers of the cloth—the lower cloth (2) and the upper cloth (1) respectively—are acted on by largely symmetrical forces. The cloth in the temple arrangement is drawn against frictional resistances through a gap (440) between two stationary surfaces and is at the same time stretched transversely to the transport direction by lateral temple arrangements (45).

    Abstract: The method for weaving a double layer cloth (1, 2) serves in particular for the manufacture of airbag cloths. It is carried out using a weaving machine which includes, between the weaving sley (3) and the cloth beam (10), a temple arrangement (4) which is arranged directly after a beat-up edge (30), a deflection element (5′) for the cloth (1, 2) and a drive roller (6). The produced cloth is transported away from the beat-up edge with the drive roller and using suitable means in such a manner that both layers of the cloth—the lower cloth (2) and the upper cloth (1) respectively—are acted on by largely symmetrical forces. The cloth in the temple arrangement is drawn against frictional resistances through a gap (440) between two stationary surfaces and is at the same time stretched transversely to the transport direction by lateral temple arrangements (45).
