4. Operational Workflow

• Loading: The wide jumbo roll is loaded onto the hydraulic unwinding shaft.
• Threading: The paper web is threaded through the guiding rollers and tension control system.
• Slitting: The paper passes through the slitting section, where it is cut into multiple narrow strips using precision blades.
• Rewinding: The narrow strips are simultaneously rewound onto cores on the rewinding shaft under controlled tension.
• Cut-Off & Ejection: Upon reaching the preset length or diameter, the rolls are automatically cut and ejected.
• Data Management: The CNC system logs production data, including length, speed, and batch information.
