Abstract: A computer reviews card designs for color changes in a fabric pattern that might cause mixed contours in the fabric woven by a Jacquard design. The computer displays problem positions of the card designs that cannot be corrected by correction lift plans and suggests changes to the card designs. When permitted the computer automatically changes the card designs to avoid mixed contours.

Abstract: The object of the invention is to provide an artificial turf which no longer requires the application of a coating on the back of the ground fabric in order to secure the plastic blades of grass. The object of the invention is achieved by providing an artificial turf comprising a ground fabric and a number of plastic blades of grass protruding from the ground fabric in which said turf, as a result of the weave structure, has a pile fixation of at least 15 N.

Furthermore, this invention relates to a rapier rod profile for a rapier weaving machine provided with a toothed rack according to the invention.

Abstract: A device for actuating binding and tension warp yarns, with at least one first shed forming device for actuating the tension warp yarns, and at least one second shed forming device for actuating the binding warp yarns. The first or the second shed forming devices are provided with a central drive to actuate the respective yarns. A pile weaving machine is provided with such a device.

Abstract: The present invention relates to an artificial turf (1) and a method for producing an artificial turf (1) comprising a ground fabric made from synthetic ground warp yarns and synthetic weft yarns and a number of plastic blades of grass (2) protruding from the ground fabric in the shape of pile burls which succeed one another in the warp direction and which each comprise two pile legs (2a), in which at least three and at most nine weft yarns (3) are inserted between two successive pile legs (2a). In particular, each pile leg (2a) is tied up around a different weft yarn (3) which are both situated between the two pile legs. As the distance between the two pile legs of a pile burl is only half that of the distance between the pile legs during tufting, the material consumption in terms of plastic grass blade yarn will be greatly reduced. In addition, artificial turf (1) of this type has the advantage that the pile burls and in particular the plastic blades of grass are evenly distributed across the fabric.

Abstract: A weaving method and a fabric (1, 2) woven by the present method includes a ground fabric (100, 200) composed of ground warp yarns, one or more binding warp yarns (101, 201), first weft yarns (3) and second weft yarns (4a, 4b, 4?, 4?) which are tied up in the ground fabric. Additionally, one or more tension warp yearns (102, 202) and non-figure forming and/or figure forming pile warp yarns (6, 7), with figure forming pile warp yarns (6) form figure-forming pile burls (6a, 6b). At least one set of two successive figure forming pile burls (6a, 6b) in the warp direction are alternately tied up over the first weft yarn (3). The first weft yarn is situated on the back of the fabric (1, 2) outside the ground fabric (100, 200), and over the second weft yarn (4a, 4b, 4?, 4?).
