Jumbo Roll Slitter Rewinder
The Jumbo Roll Slitter Rewinder is engineered for high-capacity processing of heavy material rolls. It efficiently converts large-diameter master rolls of paper, board, and non-woven materials into precisely slit finished reels, providing the structural stability and torque required for heavy-duty industrial converting.
Our Jumbo Roll Slitter Rewinder is engineered for the high-efficiency slitting and rewinding of various jumbo rolls and heavy-duty web materials:
- Premium & Printing Paper: White board/cardstock, wood-free offset paper, kraft paper, and art/coated paper.
- Specialty Paper: Newsprint, carbonless paper, glassine/glazed paper, and filter paper.
- Functional & Industrial Materials: Laminated paper, silicone-coated paper, and various types of wrapping/packaging paper.
- Flexible & Composite Materials: Non-woven fabrics and paper-plastic composite materials.
Features
- Synchronized Control: Utilizes servo motors for synchronized operation and automatic taper tension control with center winding.
- Stability: Equipped with variable frequency speed regulation to ensure smooth acceleration and stable high-speed operation up to 400m/min.
- Intelligent Monitoring: Integrated with automatic meter counting and alarm systems to minimize downtime and material waste
- Rewinding Structure: Features a dual A/B air-expansion shaft configuration with a motorized chain-driven discharge system for convenient and efficient finished roll unloading.
- Web Guiding: Employs a static analog-type edge position control (EPC) system for precise unwinding.
- Precision Slitting: Features a circular knife slitting system with a high-pressure blower for automatic waste edge discharge.
- Automated Roll Loading: Includes a shaftless hydraulic loading system for mater rolls.
