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.

        5.Control System (CNC Controller)

The machine is powered by a state-of-the-art CNC controller, offering:

• Programmable Recipes: Save and recall settings for different paper types and roll specifications.
• Real-Time Monitoring: Display of speed, tension, length, and fault alerts.
• Fault Diagnosis: Automatic detection and display of system errors with troubleshooting guidance.
• Remote Access: Optional remote monitoring and maintenance support via industrial IoT integration.
