Paper Rewinder for Corrugated and Kraft Paper Mill
The top paper rewinder is specifically designed for processing jumbo rolls from the paper machine into finished rolls with precise width and consistent tightness. This paper mill machine features an innovative top paper feeding system that ensures stable web transport and eliminates telescoping during rewinding. The rewinder incorporates a robust dual-support roller arrangement driven by a heavy-duty variable frequency drive, delivering smooth acceleration across a wide operating range.
A pneumatic braking system on the unwind stand maintains constant web tension throughout the roll diameter change, preventing wrinkles and breaks. The rewinder also includes a multi-blade slitting section with upper circular knives and a hardened bottom blade roll, allowing clean, burr-free cuts for packaging grades such as corrugated medium, kraft liner, and tube paper. Hydraulic control of the nip load and a paper pushing device enable fully automated roll ejection, reducing cycle time. With its frame construction designed for high rigidity and vibration resistance, this rewinder ensures years of reliable service in demanding mill environments.
