Abstract
A face-to-face weaving machine comprising upper (5) and lower spacers (6) for extending in the warp direction between two fabrics (12), (13) and a weft insertion device (2), (3), (4) for inserting weft yarns (22) between the spacers (5), (6), said spacers being carried out as a rigid element with a first (5c), (6c) and a second part (5B), (6B), the vertical intermediate distance between the first parts (5c), (6c) of the spacers (6) being shorter than said distance between the second parts (5B), (6B) such that the weft yarns (22) can be inserted between said second parts (5B), (6B).This invention also relates to a method for weaving pile loop fabrics, in which at least three weft yarns (14, 15, 22) are inserted above one another during successive weft insertion cycles on a face-to-face weaving machine, in which an upper (12) and a lower backing fabric (13) are woven, and loop weft yarns (22) are inserted between the two fabrics (12), (13) and are kept at a distance of the backing fabrics (12), (13), and in which pile warp yarns (23-28) form pile loops over loop weft yarns (22), so that two pile loop fabrics are woven, whereas pile warp yarns (23-28) are interlaced in the upper (12) …
