Abstract:
A warp tension control method by which the let-off motion of a loom is controlled to regulate the tension of the warp yarns. A force of the same dimension as the controlled variable, namely, the tension of the warp yarns, is applied to a mechanism supporting the tension roller of the let-off motion for displacement under the control of an electric control system to control the warp tension at a high accuracy.
