A method for manufacturing fabrics with a rib structure, in particular false bouclé fabrics is provided. On a weaving machine two series of warp threads (4, 5, 6, 10, 11); (7, 8, 9, 12, 13) are provided for weaving a respective fabric (21); (22). In successive insertion cycles, in each case, at least three weft threads (1), (2), (3) are inserted one above the other between the warp threads, so that in each case a set of weft threads (3), (2); (1), (2) running one above the other are inwoven by the warp threads (5), (6); (8), (9) of one of the other two series, and at least one weft thread (3); (1) is inwoven by the warp threads (8), (9); (5), (6) of the other series, so that two fabrics (20), (21) with a rib structure are woven simultaneously. A method for manufacturing loop pile fabrics is provided. Two fabrics (20); (21) are manufactured according to the above described method, and at least one weft thread (2) of each set of weft threads (1), (2); (3) (2) running one above the other functions as loop weft thread and is removed so that the pattern warp threads (10), (11); (12), (13) running above these sets form loops. The fabrics are manufactured according to the above mentioned methods, in particular false and true bouclé fabrics.
A method for manufacturing fabrics with a rib structure, on a weaving machine comprising forming a fabric with weft threads and a series of warp threads, sets of at least two weft threads running one above the other, pattern warp threads alternately interlaced in the fabric and rib-formingly passed around a set of weft threads, weaving a fabric with two series of warp threads, wherein in each insertion cycle of a number of successive insertion cycles, in each case, at least three weft threads are inserted one above the other between the warp threads such that in each case a set of weft threads running one above another are inwoven by the warp threads of one of the two series, and at least one weft thread is inwoven by the warp threads of the other series thereby weaving two fabrics a rib structure.
Fabric with a rib structure comprising weft threads inwoven by warp threads, sets of at least two weft threads running one above another, pattern warp threads alternately interlaced in the fabric and running rib-formingly above a set of weft threads, backing weft threads inwoven by binding warp threads such that a backing fabric is formed, wherein each set of weft threads located one above the other comprises a backing weft thread and a pattern weft thread extending above and not inwoven in the backing fabric, and pattern warp threads alternately interlaced in the backing fabric by a backing weft thread located between two sets of weft threads and passed around a pattern weft thread.
The method for manufacturing loop pile fabrics on a weaving machine comprising two series of warp threads and weft threads are inserted between the warp threads for weaving a top and a bottom fabric with loop warp threads alternately interlaced in the fabric and are loop-formingly passed around a loop weft thread, the loop weft threads subsequently removed so that two loop pile fabrics are obtained simultaneous, the two fabrics being manufactured with at least one weft thread of each set of weft threads running one above the other functioning as loop weft thread and is removed so that the pattern warp threads running above the sets of weft threads form loops.
