Machine manufacturing built on process knowledge

High-speed roll-to-sheet cutters

1. Materials: 40–550 g/m² carbonless, writing, offset, coated, metallised and kraft-liner papers. Stock down to 28 (20) g/m² requires a special specification when ordering.

2. Web width: 1400, 1600, 1800, 1900 or 2000 mm. Guide rollers are 100 mm wider than the web.

3. Unwind diameter: up to 1600 mm; 1800 mm is available to special order.

4. Cut length: 450–1500 mm.

5. Unwinds: two to six rolls. Previous machines have handled up to 14 rolls of 20 g/m² stock.

6. Cutting arrangement: rotary upper knife with a fixed lower knife. A twin rotary-knife arrangement can cut stock up to 1200 g/m².

7. Cut accuracy below 1000 mm: ±0.5 mm as standard, ±0.2 mm for reinforced models, or ±0.1 mm for high-precision models. Above 1000 mm: ±0.1% for the standard specification, with corresponding options for the other models.

8. Maximum mechanical speed: 300 m/min or 350 sheets/min.

9. Actual cutting speed depends on sheet length and grammage. At 450–850 mm, 200–300 g/m² stock or two layers of 150 g/m² stock can reach 350 sheets/min.

10. Unwind tension: automatic control with magnetic-particle brakes, or pneumatic brakes.

11. Loading: hydraulic unwind with a rail-mounted trolley. Rails are included in the quotation; the customer provides the floor channels and concrete work.

12. Standard supply: three-phase 380 VAC, 50 Hz. Three-phase 220 VAC, 60 Hz is available as a non-standard option.

13. Standard air pressure: 0.8 MPa.
