3. High precision cutting knife system
1) Upper and lower knives are rotary make the cutting accuracy is very precision.
2) Anti-curve device Include one set of square bar and steel
wheel. When the curve paper through paper edge unit that can adjust the paper square and let it flat.
3) 5 sets slitting knives
Upper slitting knife take by air pressure and spring. Lower knife connect with bear drive(the diameter is Ф180mm ) and move with spring. The upper and lower round knife is made by SKH.The lower slitting knife (diameter is Ф200mm) and drive with in-phase belts. The lower slitting knife is 5 groups, each group have two knife edge.
