1. The machine is mainly used to slit stick paper, craft paper, and other kinds of paper. 2. Entire machine is controlled by PLC (two vector motors), manmachine interface, screen touch operation. 3. Unwind part adopts imported pneumatic brake control, the rolling diameter is automatically calculated by PLC, to achieve constant tension control. 4. Traction control is drive by a vector variable frequency motor, to achieve constant linear velocity control, and effectively cut off interactant tension between rewindand unwind. 5. Rewinding part uses the vector frequency conversion motor, to drive magnetic powder ciutch, realized by the PLC automatic diameter counting, auto tension control. 6. Unwind part adopts hydraulic power feed, which can save much labour force, and shorten time. 7. Auto meter presetting, EPC error correction device is positive to assure the accuracy. 8. The feature of machine is stability, security, efficienct, etc.
