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.

Abstract: An equipment of a weaving machine in which pile warp yarns (7–13), (16–22) extend through the space between the reed dents and are distributed between a number of pile warp yarn systems and provided on the weaving machine to weave a pile fabric. A group of pile warp yarns (7–22) extend through each space between the reed dents and comprise pile warp yarns of at least two pile warp yarn systems (7–13), (16–22). Because of this it is possible to weave pile fabrics having higher pile densities at a certain reed setting. It is an easy and quick method to modify the equipment of a weaving machine, maintaining the reed setting and the pile warp yarns of each space between the reed dents being distributed between at least two pile warp yarn systems. Furthermore, a weaving process is provided in which, per space between the reed dents the pile warp yarns (7–13), (16–22) of at least two pile warp yarn systems are supplied and a pile fabric woven in that manner.
