ESecond, the machine main components The machine consists of corrective unwinding institutions, cutting structure, the rolling bodies, transmission and electrical control. Agencies main configuration and specifications (A) unwinding institutions The device has a manual aspect of offset can be eliminated due to the tension of raw material at both ends arising from Bohou or paper core non-circularity different and wrinkled. Unwinding tension to the high linear magnetic powder brake actuator output torque balancing the tension fluctuation can be reduced to a minimum. Unwinding specifications: maximum width of700mm, phi diameter 1000mm Paper tube clamping method: air shaft clamping   Specifications: 3in 1 root of the air shaft 1 piece          A pneumatic gun 1 piece Tension control: closed-loop tension control.       The output control: 200N.M 1 piece magnetic brakes 1 piece Correction perform: tracking the substrate by the photoelectric eye correction controller for a given signal, the motor drive ball screw execution.   Specifications: photoelectric eye 1 piece          Two linear bearings4 piece          A corrective institutions 1 piece          The photoelectric eye fine-tuning 1 sets (B) cutting machine configuration  M, mechanical speed 150M/min
