Background

At present, the tension and the distribution of the spinning fiber are one of the important factors in the spinning forming process. The spinning winding needs a certain tension, the tension is moderate, and the fluctuation is small, so that the spinning winding can be wound into a firm package. If the tension is too large, the end face of the roll package can generate the phenomena of wrinkling and edge expansion; if the tension is too low, the package becomes soft, and "edge stepping" and "knocking over" are likely to occur during unwinding. Therefore, the control of the tension and the adjustment of the uniformity thereof in the spinning process are critical to the production of products with uniform performance and reasonable package.
