About Slitter Rewinder Machine

Automatic slitting rewinding machine is a device for cutting jumbo roll like paper,plastic film into many narrow rolls,which is commonly used in paper making machine and packing machine.It uses a motor to drive unwind/rewind shaft. There is with magnetic brake/clutch on unwind/rewind shaft,resistance is controlled by magnetic clutch to control the tension.

Magnetic brake/clutch is special automatic component.It is transferred torque by magnetic powder to change the excitation current and magnetic state,so that adjust torque.It can be used from zero to steple adjustment at high speed and medium-small power.

The main feature of slitter rewinder is magnetic clutch as resistsance device,it will output a DC voltage by system to control the resistance by magnetic clutch.The advantage is,it regards as passive device to control small tension.
