Abstract
A textile machine in the form of a warper for drawing multiple strands from a creel and for winding the strands on a rotatable beam which forms part of the warper. Located between the creel and the beam is a strand guide and tension isolator comprising a motor-driven delivery roller and two nip rollers. Load cells are associated with one of the nip rollers and produce signals which vary substantially linearly as a function of changes in the tension of the strands between the final nip roller and the beam. The load cell signals are used to control the drive motor for the delivery roller so as to cause the motor to reduce the torque applied to the delivery roller when the tension increases and to increase the torque applied to the delivery roller when the tension decreases.
