Paper Slitting & Sheeting

Integrated corona discharge anti-static bars neutralize surface charge to <30V across the web, while closed-loop tension control (±0.3N) prevents sheet edge flutter that causes misregistration. For high-speed post-print finishing, the system’s non-slip nip rollers eliminate double-feeding even on glossy coated stocks.

Yes. The servo-driven unwind uses diameter-compensated torque control to eliminate sudden tension spikes that cause web breaks, while air-knife assisted blade oscillation produces shear cuts with <1μm edge roughness. Anti-wrinkle roller bars prevent buckling on webs as thin as 35gsm, with break rates below 0.01% during 400m/min runs.

The rewind assembly uses load-cell monitored independent nip rollers that apply pressure only to the outer wound layers, eliminating core compression even on heavy-gauge webs. Crush-resistant shear blades with optimized clearance angles prevent edge chipping, while taper winding adjusts build pressure to deliver uniformly round, non-deformed rolls ready for die-cutting or folding.

Fully motorized blade positioning with laser-guided edge alignment completes width changes in <60 seconds, with auto-loading of pre-programmed tension and blade clearance presets per material ID. Changeover scrap is limited to <0.8m of leader/trailer material, with zero trial-run waste as the first slit roll meets ±0.15mm tolerance immediately after adjustment

Non-contact winding design eliminates roller friction that causes surface scratching or fiber pull-out, while low-vibration shear cutting preserves the bond between coating and base stock to prevent edge delamination. Integrated post-slit vacuum extraction removes loose edge fibers and dust, ensuring clean edges for flawless gluing, printing, or die-cutting downstream.
