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.
