Abstract: A measuring apparatus for the measurement of the cloth tension in weaving machines comprises a probe element and a guide part to which the probe element is connected in order to guide the probe element. The measuring apparatus furthermore comprises a holder to which the guide part is secured and a sensor element which is in contact with the probe element in such a manner that a force which acts on the probe element causes a corresponding change in the sensor element. In this the guide part is attached at one side to the holder, the probe element is spaced from the attachment of the guide part, and the measuring apparatus is executed as a module.

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: An apparatus at a weaving machine serves for the protection of persons in danger regions which extend about a beat-up edge along a weaving width and beyond the latter. In this apparatus, monitoring means which emit and register light beams are arranged about the danger regions. Signals which arise as a result of an encroachment into the danger regions and through which an operating stop of the weaving machine can be triggered can be produced in the monitoring means by means of the light beams. First monitoring means are associated with a more comprehensive region and second monitoring means are associated with a central region, the actual danger region. During a normal operation of the weaving machine the first monitoring means are in an active state which ensures the protection. An activation of the second monitoring means is provided for use during activities which are occasionally to be carried out at the weaving machine within the more comprehensive region.

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).
