Stretch Wrapping for Paper Rolls, Wire Coils and Cylinders
In industries ranging from paper manufacturing to metal processing and cable production, cylindrical goods such as paper rolls, copper coils, steel wire spools, and tire assemblies present unique logistical challenges. These high-density, heavy-duty loads are inherently unstable during transport and storage—prone to loosening, end-face damage, moisture ingress, and radial slippage. Manual wrapping is not only inefficient but also dangerous due to the risk of uncontrolled roll ejection or crushing injuries. Standard pallet wrappers fail to deliver complete coverage, especially on both end faces, leaving critical areas vulnerable. The result? Increased product defects, higher return rates, elevated insurance premiums, and significant downtime from handling accidents. For enterprises operating at scale, these inefficiencies translate into direct revenue loss and diminished brand reputation.
What This Operation Demands
The packaging of cylindrical cargoes demands a solution that ensures complete 360° encapsulation, including both axial ends and the full radial surface, while maintaining structural integrity under dynamic load shifts. High-throughput environments require consistent cycle times without compromising wrap quality, and operations must minimize manual labor due to safety regulations and rising wage costs. Protection against environmental factors like dust, humidity, and mechanical abrasion is non-negotiable—especially for sensitive materials like paper reels or precision-engineered wire coils. Additionally, the equipment must accommodate a broad range of diameters (Φ600–Φ1300mm) and widths (600–1600mm), with minimal setup time between different batch types. The system must also integrate safely with existing workflows—whether using forklifts, pallet jacks, or conveyor lines—without requiring extensive facility modifications.
How the Equipment Meets It
The HYP2000F-AU Fully Enclosed Cylindrical Roll Stretch Wrapping Machine delivers a purpose-built solution engineered specifically for these demanding applications. Its core design leverages self-rotating rollers that drive the cargo’s rotation through friction, eliminating the need for external clamping mechanisms that can damage delicate surfaces. This allows for seamless, continuous six-sided wrapping—covering the entire cylindrical body and both end faces—without dead zones. The machine’s turntable diameter of Φ2000MM / 78.7" and roller width of 1650MM / 65" support payloads up to 1500KG / 3307LB, ensuring robust performance even with the heaviest industrial reels.
The PLC programmable control system enables precise configuration of wrapping layers, over-top time, and height—critical for achieving optimal film tension across varying roll sizes. With turntable speed adjustable from 0–14 rpm and roller speed up to 12 rpm, the system adapts seamlessly to both slow, controlled wraps for large-diameter rolls and faster cycles for smaller, lighter cylinders. The pneumatic auto-ejection unloading mechanism, powered by airbag-type cylinders operating within 0.6–0.8MPa, smoothly lifts and pushes the finished roll out after packaging, enabling fully automated workflow integration.
For consumable efficiency and durability, the film carriage features a wear-resistant rubber roller and a powered pre-stretch system capable of up to 250% stretch, significantly reducing film usage while enhancing load stability. Integrated proximity switches ensure accurate film feeding, preventing slack or over-tensioning. The machine’s heavy-duty slewing bearing (model 011.40.920) and K-series helical-bevel gear reduction motor provide long-term reliability under continuous operation, while the oil-water separator-equipped solenoid valve control protects pneumatic components from contamination.
This machine is ideal for environments where end-face protection and moisture resistance are critical, such as in paper mills or textile facilities. By combining full enclosure with consistent pressure application, it prevents dust accumulation and water penetration—key advantages over open-loop systems. Operators benefit from simple one-touch operation: once parameters are set via the control panel, pressing “auto-run” initiates the entire process. The system also supports remote monitoring and data logging through optional PLC interfaces, aligning with Industry 4.0 readiness.
Practical Setup Notes
Installation of the HYP2000F-AU requires a level floor space measuring at least 2700×1700×2750mm / 106.3×66.9×108.3" (machine size). The 380V/50Hz (3-phase 5-wire) power supply must be dedicated to avoid voltage fluctuations. An external air compressor delivering 0.6–0.8MPa is mandatory for the pneumatic ejection system. The roller center distance of 420MM / 16.5" ensures compatibility with standard roll cores and minimizes alignment issues. Operators should train on the touch-screen interface to configure wrapping sequences, and all personnel must follow lockout/tagout procedures during maintenance. While the machine operates autonomously, regular inspection of the rubber rollers, proximity sensors, and pneumatic cylinders is recommended every 500 hours of use. For facilities using multiple roll types, quick-change tooling kits are available upon request to reduce changeover time.
Results You Can Expect
With the HYP2000F-AU in place, businesses achieve measurable improvements across multiple KPIs. First, product defect rates drop by up to 70% due to complete, uniform film coverage that prevents edge damage, moisture exposure, and core slippage. Second, labor costs decrease by over 60%—no longer requiring two or more workers to manually secure and wrap each roll. Third, film consumption is reduced by approximately 30–50% thanks to the 250% powered pre-stretch capability. Fourth, throughput increases to 12–18 wraps per hour, depending on roll size, enabling high-volume production runs without bottlenecks. Finally, safety incidents related to roll ejection or manual handling have been eliminated in documented installations. The machine’s 1700KG / 3748LB weight and reinforced chassis ensure vibration-free operation even at maximum speeds, contributing to extended service life and lower total cost of ownership.
FAQ
Q: Can the HYP2000F-AU handle both paper rolls and steel wire coils? A: Yes. The machine is designed for a wide range of cylindrical goods, supporting packing diameters from Φ600–Φ1300MM / 23.6–51.2" and widths up to 1600MM / 63". Its self-rotating roller system adapts to varying surface textures and hardness levels, making it suitable for paper reels, copper coils, steel wire spools, and tire assemblies alike.
Q: Is automatic film cutting included? A: No, the HYP2000F-AU does not feature automatic film cutting. However, it includes a proximity switch-controlled film feed system that ensures consistent delivery, minimizing waste. Film is cut manually after completion. For fully automated film cutting, consider integrating with full automatic remote control wrapper in a downstream line.
Q: How does the pneumatic ejection work? A: After wrapping completes, the airbag-type pneumatic cylinder activates, lifting and pushing the wrapped roll out of the machine frame. Once unloaded, the mechanism automatically retracts and resets. This process is fully synchronized with the PLC and operates within 0.6–0.8MPa air pressure, ensuring smooth, reliable discharge without operator intervention.
