• Integrated Units: Curling and bending machine, automatic multi-cutters paper core cutting machine
• Control System: PLC (Programmable Logic Controller) with HMI (Human-Machine Interface)
• Power Supply: Standard industrial voltage ( customizable upon request )
• Production Speed: High-speed operation with real-time monitoring

3. System Composition and Functionality

3.1 Curling and Bending Machine

This unit is responsible for forming the paper into a continuous spiral tube. The machine precisely controls the tension, alignment, and gluing of the paper layers to ensure uniform thickness and roundness. The curling mechanism supports variable inner diameters within the 30–80 mm range, allowing quick changeovers for different core sizes. The bending section ensures smooth curvature and structural integrity before the tube is cut.

3.2 Automatic Multi-Cutters Paper Core Cutting Machine

Following the forming process, the continuous paper tube is fed into the cutting unit. Equipped with multiple high-precision saw blades, this machine automatically cuts the tube into predetermined lengths with clean, burr-free edges. The cutting length is programmable via the HMI, enabling flexible production of various core lengths. The multi-blade design significantly increases output efficiency and ensures dimensional accuracy.

3.3 Integrated Control and Monitoring

The entire production line is governed by a centralized PLC control system. Operators can set parameters such as core diameter, thickness, length, and production count through an intuitive touch-screen interface. Real-time diagnostics, fault alerts, and production data logging enhance operational transparency and maintenance efficiency.

4. Features and Advantages

• High Automation: Reduces labor costs and human error; enables unattended operation for extended periods.
• Precision Engineering: Ensures consistent inner diameter and wall thickness, critical for DTY yarn winding.
• Quick Changeover: Tool-less adjustments allow rapid switching between different core specifications.
• Energy Efficient: Optimized motor usage and intelligent power management reduce energy consumption.
• Robust Construction: Built with high-grade stainless steel and wear-resistant components for long service life.
• Safety Compliance: Equipped with emergency stops, protective covers, and safety interlocks meeting international standards.

5. Applications

The DTY Paper Core Making Machine is primarily used in:

• Textile mills producing DTY, POY, or FDY yarns
• Packaging companies requiring custom paper cores
• Converter units that supply paper tubes to downstream manufacturers
• Industrial facilities needing high-strength, lightweight spools for winding operations
