Abstract: Within the field of fiber, paper making, plastic and metal plating, one of the key techniques to guarantee the product quality is the control of winding tension of linear, strip and area materials. The changing pattern of the tension and the factors that influence the tension in the process of filament winding were analyzed, and a program scheme for calculating the tension control torque was provided. The actual winding results show that the formula drawn is proper and reasonable, and the fluctuation rate of the yarn tension is lower than 5%.
