Abstract: A method weaves pile fabrics with at least two different pile heights (a, b) in the same pile row, wherein the fabrics have weft threads, ground warp threads and pile-warp threads (1, 2), wherein these pile-warp threads are interlaced in the fabric, according to a pattern, in a figure-forming manner or are inwoven in a non-figure-forming manner, and which, when they are figure-forming, form pile with a well-defined pile height. The method includes a first set of pile warp threads, under light strain and at least a second set of pile warp threads under a higher strain. A device for manufacturing such fabrics is described.

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.
