Abstract:
A method for face-to-face weaving of a pile fabric on a weaving machine in successive insertion cycles comprising inserting in each cycle two weft threads generally simultaneously between binding warp threads and pile threads of the machine thereby weaving two backing fabrics, providing parts of the pile threads for forming pile according to a two-shot weave and providing other parts which are inwoven in a backing fabric, wherein two pile threads perform a pile change and successive positions (B=bottom; M=middle; T=top) of each pile thread are predetermined in relation to the weft threads in a series of successive lift plans, of which every lift plan determines the positions in relation to the weft threads of two successive insertion cycles, wherein a lift plan preceding or succeeding a pile change of at least one of the pile threads performing the pile change is replaced by a correction lift plan for preventing a pile change effect in the pile thread forming the pile prior to the pile change and after the pile change is inwoven in the bottom backing fabric,replacing either the last lift plan (B, T) prior to the pile change by a correction lift plan (T, B),or replacing the first lift plan (M, B) after the pile change by a correction lift plan (B, M) of the pile thread forming the pile prior to the pile change and after the pile change inwoven in the top backing fabric,replacing either the last lift plan (B, T) prior to the pile change by a correction lift plan (T, B),or replacing the first lift plan (T, M) after the pile change by a correction lift plan (M, T) or a correction lift plan (M, M) of the pile thread forming pile after the pile change and prior to the pile change inwoven in the bottom backing fabric,either the last lift plan (M, B) is replaced prior to the pile change by a correction lift plan (B, M), or by a correction lift plan (M, M),or the first lift plan (B, T) is replaced after the pile change by a correction lift plan (T, B), and that of the pile thread forming pile after the pile change and prior to the pile change inwoven in the top backing fabric,either the last lift plan (T, M) is replaced prior to the pile change by a correction lift plan (M, T),or the first lift plan (B, T) is replaced after the pile change by a correction lift plan (T, B), or by a correction lift plan (M, T).
