4.1. This machine adopts German Siemens PLC control system, touch screen, three sets of servo motors, servo motors are used as the main traction, and it is a speed control mode

4.2. The left and right windings are controlled by a set of servo motors, and the winding tension is automatically controlled. As the winding diameter increases, the taper increases. The motor speed decreases proportionally with the winding diameter, so that the winding is broken. It will not fly and stop automatically; automatic taper tension control, automatic tension compensation during acceleration and deceleration and stop. Can be rolled up to different diameters at the same time

4.3.
