Abstract
The present invention relates to a method for weaving pile fabrics on a face-to-face weaving machine, where, in successive insertion cycles, weft yarns (1-12) are inserted between binding warp yarns (13-16) and pile warp yarns (17-24), so that two backing fabrics (30), (31) are woven one above the another, in which groups of at least four weft yarns (1-6); (7-12) are inserted in respective openings between repeatedly crossing binding warp yarns (13), (14); (15), (16), so that each group of weft yarns (1-6); (7-12) comprises at least two pairs of weft yarns (2,3), (5,6), (8,9), (11,12) inserted above one another, and so that pile warp yarns (18), (21), (24) are interlaced in the upper (30) and in the lower backing fabric (31) alternately round the weft yarns (2), (5), (8), (11), situated on the back, of the said pairs in order to form pile burls, preferably according to a two-shot weave;The present invention likewise relates to pile fabric woven according to this method. Such pile fabrics have a good pile retention, an excellent quality of the back and a great flexibility and may be carried out at a high pile density.
