Abstract:
Method for face-to-face weaving pile fabrics whereby warp yarns (1)-(15) of a series of warp yarn systems are interwoven with weft yarns (16), (17), (18) so that a top (19) and a bottom backing fabric (20) are formed, whereby pile warp yarns (11)-(15) are alternately passed around a weft yarn (16) of the top backing fabric (19) and around a weft yarn (18) of the bottom backing fabric (20) so that they form pile, while per warp yarn system at least two non-pile-forming pile warp yarns (11), (12), (13; (14), (15) are inwoven in one and the same backing fabric (19); (20), and whereby the pile-forming pile warp yarns (11)-(15) are split between the two backing fabrics so that two fabrics are obtained, characterized in that the aforesaid non-pile-forming pile warp yarns (11)-(15) are divided per warp yarn system into at least two groups each with at least one pile warp yarn (11, 13), (12); (14), (15), and that the pile warp yarns of the different groups extend respectively at a different level in the same backing fabric (19), (20); and that the pile warp yarns (11, 13), (12); (14), (15) of different groups inwoven in the same backing fabric are separated from each other by weft yarns (17) of the backing fabric.
