Overview
What is a high speed slitting rewinding machine?
A high speed slitting rewinding machine is an industrial finishing system designed to convert wide master rolls of film, foil, or paper into narrower, precisely wound finished rolls at velocities exceeding 400 meters per minute. It utilizes advanced tension management and high-torque motor systems to maintain material integrity during the longitudinal cutting process.
Overview of Precision Slitting Technology
In the high-volume printing and converting industry, the quality of the final roll profile is critical for downstream application. Our high speed slitting rewinding machine is engineered to eliminate common defects such as telescoping, "starring," and edge burrs. By utilizing a heavy-duty cast iron chassis, the equipment minimizes resonance at peak speeds, ensuring that even thin gauge films (as low as 12 microns) remain stable throughout the path. This machine is a cornerstone for converters specializing in post-press equipment and flexible packaging.
Advanced Tension and Drive Control
Consistency is achieved through a multi-motor drive architecture. The unwind unit, slitting section, and dual rewind shafts are synchronized via a high-speed PLC. We employ magnetic powder brakes or AC vector motors on the unwind, coupled with ultra-sensitive load cells. This ensures that the web tension remains constant regardless of the roll diameter, preventing material stretch or wrinkling. For operators handling sensitive foils, the precision of our industrial machinery portfolio provides the necessary delicacy for high-value substrates.
Blade Systems and Slitting Flexibility
The machine supports multiple slitting methods to accommodate diverse materials. For high-speed paper and board conversion, the shear-cut (circular knife) system delivers clean, dust-free edges. For thin PET, BoPP, or metalized foils, the razor-in-groove or razor-in-air method is preferred. The blade holders are precisely calibrated, allowing for minimum slit widths as low as 25mm. The integration of a vacuum-based trim disposal system ensures that edge waste is continuously removed from the work area, maintaining a clean production environment.
Ergonomics and Safety Features
Modern converting requires rapid job changeovers. Our high speed slitting rewinding machine features a shaftless unwind for easy floor-loading of jumbo rolls and a swing-out rewind arm for efficient finished roll discharge. Safety infrastructure includes emergency stop cords, infrared light curtains, and shielded knife stations. These features ensure compliance with international industrial safety standards while maximizing OEE (Overall Equipment Effectiveness).
Why Choose All-in Pack for Machinery?
All-in Pack serves as both a manufacturer and an integrator, providing high-performance equipment that bridges the gap between Chinese manufacturing efficiency and European technical standards. We understand the physical properties of the materials being slit—whether it is cold foil, self-adhesive labels, or thermal paper—because we produce the materials themselves. This unique perspective allows us to calibrate our machinery for the specific nuances of your substrate.
