1. Product Name
Automatic Winding Machine – Precision Rewinding & Slitting Solutions
(Optional Subtitle: Dual Shaft / Single Shaft | Touch Screen Control | Automatic Tension Control | For Stretch Film, BOPP, & PE Rolls)
2. Key Product Highlights (Bullet Points)
-
Precision Tension Control: Equipped with advanced magnetic powder brakes or servo motors to maintain consistent tension during rewinding, preventing telescoping and ensuring tight, uniform rolls.
-
High-Speed Efficiency: Capable of winding speeds up to 100-150 meters per minute, significantly increasing production output for film converters and packaging manufacturers.
-
Automatic Edge Position Control (EPC): Sensors automatically align the material edge or center during the winding process, ensuring neat roll edges and reducing material waste.
-
Versatile Slitting: Integrated razor or shear cutting systems allow for precise slitting of large "jumbo" rolls into smaller, custom-width retail rolls (e.g., splitting 1.5m rolls into 50cm rolls).
-
User-Friendly Interface: Features a PLC touch screen control panel for easy setting of roll length, diameter, and speed, reducing the learning curve for operators.

4. Detailed Product Description
Overview
Optimize your converting process with our Automatic Winding Machine. Designed for manufacturers of stretch film, BOPP tape, and PE sheets, this machine transforms large "jumbo rolls" into market-ready smaller rolls with precision and speed. Whether you need a simple single-shaft winder for basic rewinding or a sophisticated dual-shaft turret winder for non-stop production, our machines deliver consistent quality, tight winding, and accurate slitting.
Why Choose Our Winding Machine?
-
Consistent Roll Quality: The closed-loop tension control system ensures that the film is wound evenly from the core to the outer layer, preventing loose edges or "telescoping" rolls that are difficult to use.
-
Increased Productivity: The dual-shaft (turret) model allows for continuous operation—one shaft winds while the other is being unloaded, eliminating downtime.
-
Material Versatility: Handles a wide range of materials including LLDPE stretch film, BOPP packaging tape, PET film, and aluminum foil.
-
Waste Reduction: The precise EPC (Edge Position Control) system minimizes edge trim waste, saving material costs over time.
-
Easy Operation: The PLC system stores recipes for different roll sizes, allowing operators to switch production jobs quickly with the touch of a button.
Performance Metrics
-
Winding Accuracy: Diameter tolerance within ±2mm.
-
Slitting Precision: Clean cuts without burrs or jagged edges.
-
Speed: High-speed winding reduces batch processing time.
5. Application Scenarios
-
Stretch Film Manufacturing: Rewinding large extruded rolls into standard 500mm hand and machine rolls.
-
BOPP Tape Production: Slitting and rewinding adhesive tape into standard packing tape widths (48mm, 60mm).
-
Flexible Packaging: Converting large rolls of plastic film for food packaging or agricultural use.
-
Paper & Label Industry: Rewinding thermal paper, label stock, or receipt paper rolls.
-
Textile & Non-Woven: Processing rolls of non-woven fabric for medical or hygiene products.
6. Selection Guide
-
Single vs. Dual Shaft:
-
Single Shaft: Best for small to medium businesses with lower volume requirements. More affordable and compact.
-
Dual Shaft (Turret): Best for high-volume factories. The ability to switch shafts without stopping the machine doubles efficiency.
-
Slitting Type:
-
Razor Cut: Best for thin films (stretch film, plastic bags).
-
Shear Cut: Best for thicker materials (tape, heavy-duty film, paper).
-
Tension Control:
-
Magnetic Brake: Standard, reliable, and cost-effective.
-
Servo Motor: High-precision, digital control for sensitive or very high-speed applications.
7. Frequently Asked Questions (FAQ)
Q: Can this machine slit multiple widths at once?
A: Yes, you can set up multiple razor blades or shear cutters to slit a large jumbo roll into several smaller rolls simultaneously (e.g., one 1500mm roll into three 500mm rolls).
Q: What is the maximum roll diameter it can handle?
A: Our standard machines handle unwind diameters up to 1200mm, but we can customize the stand size for larger jumbo rolls if needed.
Q: Does it come with a core loader?
A: Yes, the machine includes a mechanism to automatically or semi-automatically load the cardboard cores onto the winding shaft.
Q: Is installation difficult?
A: The machine comes mostly pre-assembled. We provide installation videos and remote support to help your team set it up and calibrate the tension.
