The magnetic clutch before cutting machine speed can not be high, because at run time could easily lead to high-speed magnetic friction, high temperature, shorten its life, and in severe stuck, blocked the machine running, to bring to production very serious consequences. Serious impact on productivity.

 Slitter traditional control scheme is the use of a large-volume motor to drive the retractable shaft, the retractable reel plus a magnetic clutch, magnetic clutch by adjusting the current to control the resistance it generates to control the material surface tension. Magnetic particle clutches and brakes is a special automation equipment, it is the work by filling in the gaps of the magnetic torque transmission, changing the magnetic current can change the magnetic state of magnetic powder, and then adjust the transmission of torque. Can be used for variable speed from zero to synchronous speed, fine-tuning for high-speed section and the small and medium-power control system. Also used to adjust the current method of regulation used to ensure the winding course of the torque to maintain constant tension open-book or rewinding tension control system.

 Slitter main feature is the resistance as a magnetic clutch device control through the system to output a DC voltage, resistance generated by magnetic powder clutch control. The main advantage is that it is a passive device that can control the smaller tension.

 Disadvantages: is not high speed, high-speed magnetic high-speed operation could easily lead to friction, high temperature, thereby causing magnetic clutch fever shorten its life. A certain width with a cutting tool to cut the longitudinal profile sheets, cut into several narrow sub-volumes used in the device. Be installed in the calendar or extrusion machine, coating machine unit device, you can complete a continuous cutting, often with a winding device. Plain film cutting knife can be used knives knife and round mouth.
