Abstract

This invention relates to a method and to a system for weaving fabrics with two useable sides (W1), (W2), in which per operating cycle one weft thread (6) is inserted, and in which each fabric comprises a first figure warp thread (1) and a second figure warp thread (2) that, in a number of operating cycles, are positioned together alternately above and below the weft insertion level, so that, at both fabric sides, these figure warp threads (1), (2) are bound over the same weft threads (6), while running above one another, and in which the mutual position (upper or lower position) taken up by the first figure warp thread (1) and the second figure warp thread (2) in each fabric (W1), (W2) during the weaving process is determined selectively according to a previously defined figure pattern, preferably by positioning the first (1) and second figure warp threads (2) in a first shed (I) at a first level (POS. 1) at one side of the weft insertion level and in a second shed (II), selectively on a different second level (POS. 2) and third level (POS. 3), at the other side of the weft insertion level. The invention also relates to fabrics (W1), (W2) woven according to such method.
