ABSTRACT:
A weaving machine weaves pile fabrics having weft yarns, backing warp yarns, and pile warp yarns. One or several spacers extend between the pile warp yarns either to realize a constant pile height between two pile fabrics formed, or to determine the pile loop height in one or several pile fabrics comprising pile loops. One or several holders clamp the spacers. One or several shed forming devices, drive heddles through which backing and/or pile warp yarns extend to position these warp yarns with respect to the weft yarns. A zone for supplying pile warp yarns extends between a yam supply and the heddles. One or several holders installed between the yarn supply and the one or several shed forming devices clamp the spacers. The holders are installed outside the said supply zone, in such a manner that the pile warp yarns will extend into the supply zone without any hindrance.
