Slipping Machine is used very frequently, it can cut thin film or thin film A paper with a uniform range of papers is probably a film. Some paper machines probably use a slitting machine for printing machines. The slitter is mainly driven by the motor in the middle of the process to drive the shaft of the reel, and the magnetic powder clutch is placed on the shaft. After the process changes the current of the clutch to adjust the resistance of the attack, thereby changing the tension of the machine.   Magnetic powder clutches and brakes are a special type of automatic actuator. It is the magnetic powder transmission torque added to the working gap through the process. By changing the excitation current, the magnetic state of the magnetic powder can be changed, and the transmitted torque can be adjusted. It can be used for stepless speed regulation from the whole end to the synchronous speed. It is suitable for fine adjustment of high speed section and speed regulation of medium and small power. It is also used to adjust the torque by means of conditioning current to ensure that the tension during the winding process is consistently constant, and the unwinding tension is restrained.   The primary characteristic of the slitting machine is that the magnetic powder clutch acts as a resistance to rest. After the process is finely restrained, a DC voltage is output to restrain the resistance of the magnetic powder clutch. The primary advantage is that it is passive and can restrain small tensions.   Its primary drawback is that the speed is not high and low, and it is easy to form high-speed friction of magnetic powder during high-speed operation, which breeds high temperature and forms a magnetic powder clutch to heat up and expand its life. The cutter is used to cut the length of the coil to a certain extent and cut into several sets of narrower rolls.   After being placed in the calender, about the extrusion machine, the glue applicator, etc., the continuous cutting can be completed, often with winding and rest. Cutting knife can be used with flat knife and round knife
