ABSTRACT:
A take-up rate and a let-off rate in warp feed on a loom are controlled while a displacement (.DELTA.L) of a cloth fell position C is taken into account. The system comprises a cloth fell position compensation circuit (2, 16, 21) which outputs a cloth fell compensation signal (.DELTA..omega..sub.c) to compenate a displacement (.DELTA.L) of the cloth fell position (C) when a weaving condition such as a target weft density (D*), a target warp tension (T*) or the kinds of weft and warp yarns is changed. The cloth fell compensation signal is added to a basic warp feed rate (.omega..sub.f) obtained from D*, so that the displacement motion of the cloth fell is completed in a shorter time. According to this compensation, a weft density of a resultant fabric rapidly coincides with the target weft density.
