High-Speed Slitting Re-winder Machines

High-Speed Slitting Re-winder Machines

High-Speed Slitting Rewinder Machine is an advanced converting system designed to slit large rolls of paper, film, foil, or other flexible materials into narrower rolls and rewind them at high speed with precision. The main design parameters of such a machine include web width (typically 1300–1800 mm), unwind and rewind roll diameters (up to 800–1000 mm), web thickness (10–300 µm for films or specified GSM for paper), and slitting speed, which can reach 300–400 m/min or higher. The machine must maintain excellent tension control—usually adjustable between 2 kg and 30 kg—to ensure uniform winding and prevent defects like wrinkles or telescoping. Structural rigidity is critical to withstand vibration and dynamic loads at high speeds, while precise web guiding systems with ultrasonic or CCD sensors keep edge deviation within ±0.4 mm.
