Abstract:
1. Method for weaving a pile fabric on a weaving loom, comprising: introducing weft threads between a number of ground warp threads which have been provided in reed dents of the weaving loom, in successive weft introduction cycles, thereby weaving at least one base fabric having first weft threads bound in on a first level situated on the pile side of the fabric and second weft threads bound in on a level which is situated on the rear side relative to the first level, and having pile warp threads that form pile tufts over respective second weft threads, determining successive positions of the ground warp threads relative to the weft threads according to a ground weave repeat which extends over at least eight weft introduction cycles, wherein introducing weft threads between a number of ground warp threads comprises binding in groups of at least one weft thread in openings between a pair of binding warp threads of the same reed dent or of adjacent reed dents, between a first and a second crossing between said binding warp threads, wherein at least one pile tuft is formed over at least one second weft thread of each group, and wherein the following applies to each pile tuft: A A B B K K=K wherein determining said successive positions of the ground warp threads with respect to the weft threads comprises determining successive positions such that at least two orientations of a first (i), a second (ii) and a third orientation (iii) of the pile tuft legs are created within the same ground weave repeat, wherein oblique orientations (i), (ii) of the pile tuft legs are obtained when at least one first weft thread and at least one second weft thread are provided for each group, in which i. the first orientation (i) is an oblique orientation which is obtained if A B ii. the second orientation (ii) is a differently directed oblique orientation which is obtained if A A iii. the third orientation (iii) is a substantially vertical orientation which is obtained if A 1 +B 2 is equal to A 2 +B 1 .
