Abstract:
A loom for weaving a pile fabric comprising:(a) a plurality of healds for shedding warp yarns;(b) a pile forming reed through which said warp yarns are guided;(c) a plurality of pile loop forming lances extending in the warp direction so that each loop forming lance has a rearward end that passes through an associated dent in the reed, each dent being defined between a pair of spaced apart dent fingers;(d) wherein each loop forming lance and at least one dent finger of said pair of dent fingers co-operate to guide lateral displacement of the loop forming lance relative to said associated dent to positively locate the loop forming lance in a desired lateral position relative to the dent;(e) wherein a first group of said healds is threaded with ground forming warp yarns, said first group of healds and said loop forming lances being arranged such that upper and lower shedding positions of said ground forming warp yarns are located below the loop forming lances;(f) a second group of healds threaded with loop forming pile warp yarns, the second group of healds and said loop forming lances being arranged such that each loop forming yarn may be moved from a lower position located beneath an associated loop forming lance to an upper position located above said associated loop forming lance; and(g) a guide system associated with each loop forming lance for guiding movement of each loop forming pile warp yarn such that during movement from its lower position to its upper position it passes by one side of said associated lance and during movement from its upper position to its lower position it passes by the opposite side of said associated lance to form a loop held upon said associated lance.
