Abstract:
Process for controlling warp tension in a weaving system having a plurality of warp threads disposed on a plurality of rotatable, self-braking bobbins, said warp threads being pulled by a withdrawal roller through a feeding stand arranged between said bobbins and said withdrawal roller, said warp threads forming a warp thread family which defines a reference plane in said feeding stand during a normal withdrawal speed of said withdrawal roller, said process comprising the acts of:deflecting said warp thread family in a controlled manner into at least one defined position relative to said reference plane as a function of a stop signal from a weaving loom control when said withdrawal roller is stopped or slowed from said normal withdrawal speed; andreturning said warp thread family in a controlled manner from said at least one defined position to said reference plane as a function of a start signal from said weaving loom control when said withdrawal roller is returned to said normal withdrawal speed.
