ABSTRACT:
A system and method for regulating the cloth fell position in a loom. The desired lengths of cloth and warp thread are determined by averaging the actual values over a given number of weft insertions. The actual lengths of the cloth and warp thread are then continuously measured and compared with the desired values during weaving to compute warp and cloth offset values. A correction factor is determined based on the offset values and the moduli of elasticity of the warp thread and cloth. The cloth fell position is then corrected by adjusting either the actual length of the cloth or the warp thread based on the correction factor.
