Abstract: Fabric support and a weaving machine using the support, in which the fabric support (1) includes several supporting elements (10, 11, 12, 13, 14, 15, 16, 17, 18, 19) which can be arranged next to one another and a profiled section (20, 30, 40, 50, 60) which is supported by the supporting elements (10, 11, 12, 13, 14, 15, 16, 17 18, 19) and includes a guide surface (22) for a fabric (3).

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 for controlling an air jet loom and, in particular, for controlling a loom used for weaving cloth having move than one pick range. One use of such cloth is for tire-cord fabric having a body portion having between 1 and 3.5 ppi and at least one tab portion having between 3.5 and 50 ppi. The system includes an automatic temple insertion device. The system further includes dual nozzles to automatically switches from tab to body; automatic pick spacing change from tab to body; and an automatic tension level control. The system permits multiple tabs on a roll for separating multiple body portions of the roll, providing an inspection segment per roll, and providing a cut line either by "no picks" or by changing the filling within the tab.

Abstract: An air jet weaving loom equipped with a rod-type expander, has a weaving reed forming a weft thread insertion channel. The expander has an extension reaching toward the channel and preferably to about the center of the channel. The extension has a top surface which forms an elongation of a fabric supporting surface of the expander. This arrangement assures that the beat-up or interlacing point is always located about centrally in the weft thread insertion channel.
Abstract: A method of and apparatus for stabilizing the fabric within the weft beat-up area in multiple-shed weaving machines or wave weaving loom wherein the beat-up is effected by means of a rotary reed. Immediately after the weft has been beaten-up, the fabric passes through a stabilization slot, and after having passed therethrough, it changes the direction of its movement beyond the level of the weaving plane.

Abstract: Apparatus for stabilizing a fabric in the travelling-wave shedding looms in a zone thereof where the weft is beaten up by beating-up projections of the disc of a rotary reed. The apparatus comprises means forming a stabilization slot, and a deflection rail downstream of said means, the top portion of said deflection rail lying above the level of the weaving plane, the means forming the stabilization slot including an upper delimitation rail having a lower edge and fixed on a continuous crossbar along the weaving plane, and a lower rail, the upper delimitation rail being an elastic stabilizing strip secured at its upper edge to the crossbar.

Abstract: Method of and apparatus for lateral tensioning or holding of fabrics at a predetermined width. The fabric is formed with at least one auxiliary longitudinal fabric strip joined to the confronting selvedge by uncovered weft threads, the uncovered weft threads being engaged and deflected alternately from above and below in the gap between said strip and the fabric by means of a lever which penetrates between said uncovered weft threads so that, said strip bears against the side of said lever which acts as a temple. Upon further advancement of the fabric the strip is removed from the selvedge thereof.
