Abstract
Method for controlling the warp let-off on weaving machines, with the characteristic that the method consists of: detecting the variation with time of at least one of the parameters which are a function of the warp tension and speed of motion of the warp threads; taking the detected signal and removing the effects due to variations in the weave pattern; and using the resulting cleaned signal to control at least one warp drive motor.
