Abstract: On the one hand, the invention relates to a method for weaving face-to-face fabrics on a face-to-face weaving machine, the fabrics (10),(20) consisting of weft yarns (2), ground warp yarns (3) and pile warp yarns (4), and one or several spacers (1) being provided in order to keep the fabrics (10),(20) at a distance during the weaving process, and a weaving reed being provided, comprising reed dents (A),(B),(C) through which the said ground warp yarns (3) and pile warp yarns (4) are extending, and through which the spacers (1) are extending every two or more reed dents (A),(B),(C), wherein the pile warp yarns (4) and the spacers (1) are separated from one another in the respective reed dents (A),(B),(C). On the other hand, the invention relates to a fabric woven in accordance with such a method and a face-to-face weaving machine designed to carry out such a method.

Abstract: A method for weaving single-layered and/or multi-layered woven fabric, especially airbag fabric, includes interweaving warp threads delivered by at least two warp beams.

Abstract: A method and weaving machine for weaving a thick reinforcing fabric comprising multiple noncleaving layers with a 2.5 D or 3 D type structure. The warp yarns successively move into a yarn joining comb, a calibrating comb and then into a dobby weaving unit, where the warp yarns on n superimposed laps are separated upstream of the calibrating comb, n being equal to (N- 1/2 ) and N being the number of layers of said reinforcement so as to have (N- 1/2 ) warp yarns moving into each tooth of the calibrating comb. Two adjacent yarns of a given tooth of the calibrating comb are threaded into the eyes of two heddles of the same row of two heddle frames of the dobby, so that the displacement planes of two adjacent yarns during formation of the shed form between them a sufficient angle so as to prevent the yarns from catching on one another.

Abstract: Mechanical device disposed behind the heddle frames of a loom for increasing the weft density in cloth weave fabrics, constituted by three parallel rollers situated horizontally at the vertices of a triangle, of which the rear roller separates the two equal sets of warp yarns while the other two front rollers are located very close together and act as an outlet guide for said two equal sets of warp yarns. The three rollers are rigid at their ends with two lateral support plates which are made to reciprocate, by means of connecting rods connected eccentrically to the loom drive shaft, about a horizontal rotational axis which lies in the center plane of the shed formed by said two sets of warp yarns, and passes in proximity to the two front thread guide rollers and at an equal distance therefrom. The three rollers are connected rigidly together by intermediate support plates.

Abstract: In accordance with the proposed method, in the course of shedding, thread length compensation after a change of a shed, and adjustment of different amounts of tension applied to tight and slack shed sides, warp threads are placed under a tension close to the looming-up tension maintained while the main shaft turns through from 250.degree. to 340.degree., and at the beat-up moment the warp threads are subjected to a maximum tension, the thread tension being increased while the main shaft turns through the remaining 20.degree. to 110.degree..

Abstract: A lease rod for textile apparatus including weaving looms and drawing in machines is disclosed comprising central enlongated hollow metal tube with inserted end tips preferably of molded synthetic plastic material the ends of the tube being disposed at an angle for engagement of complemental surfaces, the angular disposition of the engaging surfaces facilitating insertion into the system of warp threads to be separated and reducing the tendency of the threads to catch at the intersection and the end tips decreasing in thickness while spreading and with rounded surfaces to facilitate insertion into the thread systems.
