In many industries of industrial production, winding control problems are often encountered. In the production process of paper, textiles, plastic films, wires, printed materials, magnetic tapes, metal wires, etc., the unwinding and winding tension of the tape or wire is crucial to the quality of the product. Therefore, constant tension control is required, which means that the product is subjected to the best tension during the winding process and remains unchanged from beginning to end. If the tension is too high, it will cause tensile deformation of the processed material; Insufficient tension can cause stress deformation between layers of the material being rolled, resulting in uneven winding and affecting processing quality. In the strip winding system, the tension control system plays an important role and is quite complex.
