The unwinding and feeding unit is also equipped with a digitally controlled electromagnetic brake tension system. The structure of the tension control system of the unwinding feed unit and the flexographic printing machine is shown in Fig. 6. He can provide optimal tension control for different substrates and is immune to dust and dirt. Among them, the tension compensation control adopts a loop type self-detection system, which can continuously maintain the tension of the paper (or film) when the diameter of the web is continuously reduced.
