ABSTRACT:
A method for manufacturing a pile fabric whereby a backing fabric (9), (10) is woven, in which groups of at least three weft threads (1-4), (5-8) are inwoven into respective openings between binding warp threads (11), (12); (13), (14) crossing each other, and in which non-pile-forming (parts of) pile warp threads (15-19) and tension warp threads (20), (21) are woven in, while pile warp threads (15), (16), (19) are allowed to form pile loops around weft threads, and whereby of each group of weft threads a first (1), (3); (5), (7) and a second weft thread (2); (6) are provided respectively along the pile side and along the back of the tension warp threads (20); (21) and the non-pile-forming (parts of) pile warp threads (15-19), and a third weft thread (4); (8) is provided between on the one hand the tension warp threads (20); (21) and on the other hand the non-pile-forming (parts of) pile warp threads (15-19).
The weft threads (1-4); (5-8) of every group are woven in on three different levels in the backing fabrics, and can because of this be pushed one under the other. This makes a higher weft density and therefore also a higher pile row density possible.
