The present invention relates, on the one hand, to an artificial grass mat comprising a ground fabric and a number of artificial grass blades protruding from the ground fabric, at least one of the artificial grass blades being formed from a pile-warp yarn (1-6; 7-10; 15-18) having a density of less than 5,000 dtex. On the other hand, the present invention relates to a method for the production of an artificial grass mat of this type. The artificial grass mat according to the invention is suitable both for deployment in the practising of sport, such as for example football, tennis, hockey, golf and the like, and for deployment for other uses, such as for example domestic and garden applications, as a decorative landscape element.
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.

ARTIFICIAL TURF AND METHOD FOR PRODUCING A TURF OF THIS TYPE
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.

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.

Weaving machine for weaving pile fabrics, and set of at least two spacers provided to be mounted next to one another in a weaving machine for weaving pile fabrics
The invention relates to a weaving machine for weaving pile fabrics, and a set (100) of at least two spacers (1-4, 11, 12, 21, 22, 31, 32, 41 and 42), wherein the spacers (1-4, 11, 12, 21, 22, 31, 32, 41 and 42) are provided and arranged in the weaving machine in such a manner that the pile warp yarns (18, 18′) have more space during their movement in the shed-forming zone towards the fabric line in the warp direction at their entry point in the array of lancets, so that they are hindered to a lesser degree by this array of lancets.
This invention relates to a method for producing fabrics with an embroidery effect comprising a base fabric, said base fabric being manufactured on a weaving device by introducing first weft yarns (1) between the warp yarns (a,b,c,d) of a series of warp yarn systems in successive sheds, and second weft yarns (2) being introduced in such a way with respect to the warp yarns (a,b,c,d) that these second weft yarns (2) create an embroidery effect on an effect side of the base fabric, characterized in that at least two base fabrics (100, 200) are woven simultaneously, wherein one set of weft yams, comprising one first weft yarn (1) per base fabric and at least one second weft yarn (2), is introduced in a series of successive weft cycles, in such a manner that each second weft yarn (2) creates an embroidery effect over at least part of its path in at least one base fabric (100, 200), and wherein at least one second weft yarn (2) is introduced with respect to the warp yarns in such a manner that different parts thereof create an embroidery effect in at least two different base fabrics (100,200).

Method for weaving fabrics with areas having a corded structure with a large variety of colour effects
A method for weaving a pile fabric with areas having a corded structure, a backing fabric being woven on a weaving machine by inserting backing weft yarns during successive weft insertion cycles between binding and tension warp yarns, while pattern-weft yarns are inserted outside the backing fabric, and are covered by pile warp yarns forming cords. Successive series of different pattern-weft yarns are inserted into the pile fabric in areas having a corded structure and at least one pattern-weft yarn of each series is running essentially above the warp yarns in a first part of its trajectory and is forming the pattern, and is covered by pile warp yarns essentially forming cords in a second part of its trajectory, so that a predetermined pattern or design is formed. This enables the color palette and/or the effect palette to be modified across the width of the weaving machine with weft effects.
