Abstract: A clamping device (18) for temporarily clamping the fabric (2) in place is provided on the weaving machine (1), and interacts with a ventilating device (23) that effects the temporary elimination of the clamping action. The operation of the ventilating device (23) is controlled by the movement of the beat-up device (11) via a mechanical connection that exists between the beat-up device (11) and the clamping device (18), and is effected by a mechanical transmission (28)—to be understood in the broadest terms—via which the clamping force can be eliminated or also generated in some embodiments. Due to the controlled release of the fabric at times or during phases of operation of the weaving machine (1) that can be adjusted and selected, a simple adaptation of the operation of the weaving machine (1) to different types of fabric can be achieved. An operation with less longitudinal pull of the fabric is possible.

Abstract: A fabric spreader arrangement for a loom includes a spreader rod rotatably received in a hollow space of a spreader body. The fabric is looped around the spreader rod in the hollow space. To achieve a low wear, a light weight, and an excellent fabric spreading effect, the spreader rod is a one-piece hollow cylindrical metal body extending entirely over the weaving width, preferably made of V4A stainless steel, having an outer diameter of at least 10 mm (and preferably 15 mm) with a wall thickness of at least 0.4 mm (and preferably 0.7 mm), and having an outer circumferential surface that has been surface treated to achieve a surface roughness with a peak-to-valley roughness measurement of at least 10 ?m (and preferably 20 to 50 ?m).

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: A device for producing at least two tubular belt bands that are turned inside out, where each of the belt bands has two fabric layers on top of one another and connected to each other in a longitudinal direction by woven hems to form a cavity. Warp threads of the layers have a uniform warp thread density over an entire length of the belt bands. The device includes a power loom having a shedding mechanism with a reed with parallel dents, a weft insertion device extending over an entire width of the power loom, a control unit for controlling the shedding mechanism, and an expander extending over the entire width of the power loom. The expander has a smaller diameter in a tubular area than in a hem area in correspondence with the belt bands to be produced so that clamping pressure of the expander is substantially constant over an entire width of the woven fabric. A thermal cutting device has cutting heads that are operative to cut out the belt bands in the hem area from the woven fabric web.

Abstract: The bar type temple (2) consists substantially of a bar carrier (23), a working bar (3) and at least one sliding bar (41). The working bar and the sliding bar are arranged parallel to one another in the bar carrier. The bar type temple has the advantage that the clamping of the web is low without the maintenance of the width of the web being impaired.

Abstract: A guide device for a web of material at a point of a textile machine, preferably a weaving machine, at which the web of material is produced. The guide device includes a first guide strip with a guide edge which first guide strip is arranged subsequent to the point at which the web of material is produced and a second guide strip with a guide edge which second guide strip is arranged subsequent to the first guide strip. The guide strips extend in each instance along the entire width of the web of material and overlap one another in such a way the web of material is guided at least approximately in an F-shaped manner. The guide edge of the second guide strip is formed by a rotatable round bar. The rotatable round bar is arranged in a loose manner in such a way that is is supported, under the influence of the tensile stress of the web of material, along the web of material at the first guide edge and in direct contact at the end face of a guide element of the second guide strips.

Abstract: The present invention refers to a temple for holding or for laterally tensioning a woven fabric, in particular on weaving looms, comprising endless guide means having displaceably arranged therein members provided with needles for engagement with said woven fabric, said guide means extending and being arranged in such a way that the needles of at least two members are simultaneously in engagement with the edge of the woven fabric and that, in the course of the needling-in operation, the needles brought into engagement with the woven fabric, are located at a greater distance from the longitudinal axis of the width of woven fabric than in the course of the de-needling operation. The failures occurring in the case of such a temple are now eliminated by providing an appropriate amount of play between the individual members and by guaranteeing at the same time that the members are returned to the point of needling-in in an appropriate manner.

Abstract: The cover for the retaining member of a temple has a threaded rod either rotatably or fixedly attached to each cover leg. The threaded rod rests on the fabric. The rod preceding the retaining member in the direction of advance of the fabric advances the point at which the spreading effect of the temple becomes operative. The threaded rod affixed to the leg of the cover which follows the retaining member in the direction of advance of the fabric relieves the retaining member of load and thereby decreases the possibility of damage to the fabric. The cover with threaded rods is useful whether the retaining member contacts the bottom of the fabric, with the cover on top, or the retaining member contacts the top side, with the cover below, and the threaded rods riding on the underside of the fabric.

Abstract: A fabric or cloth templing device for a loom comprises a part provided with a temple containing a porcupine or needle roller or ring. Over the temple there extends a domed cover member in order to place the selvedge or marginal region of a cloth or fabric web into contact with the needled jacket surface or shell of the porcupine roller or ring. Arranged after the temple is a contact roll which coacts with a countersurface, in order to subsequently fixedly retain the fabric which has been spread by the porcupine rollers. By virtue of these measures it is possible to ensure in a most simple manner an effective traction relief with increasing fabric tension.
