Ring & Coil Wrapper Vertical (Small)
Vertical ring wrapping machine for small coils: bearings, wire coils, small cable reels, hose coils. Wraps ID300-500mm × OD500-800mm, width 50-150mm, 25-40 pieces/hour. 0-80rpm, 200kg capacity, 200mm roller height. Compact 1100×1090×1800mm.
Overview
The PW-RV800 is our vertical ring wrapping machine for small coils, designed for wrapping ring-shaped products such as bearings, small wire coils, cable reels, hose coils, rubber rings and similar toroidal items. The product sits vertically on support rollers while a wrapping ring passes through the center hole and orbits around the circumference, applying stretch film or packaging tape in a continuous spiral pattern.
Accommodates coils with inner diameter 300-500mm, outer diameter 500-800mm and width 50-150mm, with a throughput of 25-40 pieces per hour. The support rollers are positioned at 200mm height, and the wrapping ring rotates at 0-80rpm with variable speed control. Maximum coil weight is 200kg. The compact footprint of 1100×1090×1800mm fits easily in small workshops.
The vertical ring wrapping pattern provides complete coverage of both inner and outer circumferential surfaces, protecting coils from dust, moisture and damage. The machine is simple to operate — place the coil on the rollers, thread the film, and start the cycle. Ideal for bearing manufacturers, wire producers, cable companies and hose manufacturers. CE certified, with optional ID/OD range extension, tape wrapping and custom configurations available.

Understanding the Coil Wrapping Process
Step-by-step operation for consistent coil protection.
Load Small Coil Vertically
Place the small coil vertically onto the wrapping platform using a forklift or manually. The vertical small ring wrapper handles coils up to 800mm outer diameter and 800mm height, with inner diameter from 200mm. The platform automatically centers the coil for consistent wrapping.
Ring Positions Around Coil
The vertical wrapping ring positions around the coil. Photo-eye sensors detect the coil dimensions and automatically adjust the wrapping ring diameter and film tension. No manual adjustment needed for different coil sizes within the capacity range.
Film Attaches to Coil
The film tail is automatically attached to the coil using a mechanical clamp system. The system verifies film attachment before starting the wrapping cycle. For delicate coils, the operator may select a gentle film tension setting to prevent damage.
Vertical Ring Wrapping Cycle
The vertical ring rotates around the stationary coil, applying stretch film in a spiral pattern from bottom to top. The film carriage moves vertically while the ring rotates, creating a consistent, overlapping wrap pattern that fully covers the coil circumference and both end faces. Film tension is precisely controlled to prevent coil deformation.
Film Cut & Coil Removed
Once the wrapping program completes, the film is automatically cut and clamped for the next cycle. The vertical ring returns to home position. The operator removes the wrapped coil with a forklift or manually. The system is immediately ready for the next coil, achieving 15-30 coils/hour depending on size.
How to Choose the Right Ring Coil Wrapper Vertical Small
Key factors for your specific coil wrapping operation.
| Factor | Recommendation |
|---|---|
| Coil Size Range | Standard up to 800mm OD, 800mm height, 200mm minimum ID. Custom sizes available for slightly larger coils. Measure your largest coil before ordering. |
| Coil Weight | Standard capacity up to 1000kg. Because coil remains stationary, weight capacity is limited only by platform strength. Custom capacity available for heavier coils. |
| Coil Type | Designed for vertical wrapping of cylindrical coils. Ideal for cable drums, wire coils, yarn cones, and similar products. Not suitable for horizontal coils or standard pallets. |
| Throughput | Rated 15-30 coils/hour depending on coil size and wrapping program. For higher volumes, consider multiple machines or automated loading systems. |
| Film Type | Uses 300-500mm wide machine-grade stretch film (15-23 micron). Pre-stretch ratio up to 200%. Film consumption typically 10-30g per coil depending on size. |
| Floor Space | Footprint approximately 2000×2000mm. Requires adequate ceiling height of 2500mm minimum for vertical ring movement. Compact design fits easily in small production areas. |
Expert Selection Tips
- Vertical ring wrappers are specifically designed for coils standing vertically — not suitable for horizontal coils
- Measure your coil outer diameter, inner diameter, and height before ordering to ensure capacity
- For delicate coils (yarn, fine wire), use lower film tension settings to prevent deformation
- Consider adding VCI film option for metal coils requiring corrosion protection
- Vertical wrapping provides full coverage including both end faces — superior to manual wrapping
- Request factory test with your actual coils to verify wrapping quality and film consumption

Common Troubleshooting
Symptom: Vertical ring does not rotate
Cause: Drive motor overload, VFD fault, drive belt broken, or safety guard interlock triggered.
Solution: Check VFD display for error code. Reset motor overload. Inspect drive belt. Verify all safety guards closed. Check ring bearing for seizure. Contact support if VFD error persists.
Symptom: Film breaks during wrapping
Cause: Film tension too high, film quality poor, pre-stretch ratio too high, or sharp edges on coil.
Solution: Reduce film tension setting. Verify film is machine-grade 15-23 micron. Lower pre-stretch ratio. Check coil for sharp edges or burrs. Verify film roll feeds freely. Check film carriage alignment.
Symptom: Coil not centered on platform
Cause: Centering mechanism faulty, platform misaligned, or sensor calibration off.
Solution: Check centering mechanism operation. Verify platform is level. Calibrate photo-eye sensors. Check coil guide rails. Clean sensor lenses. Adjust centering parameters in PLC.
Symptom: Wrapped coil has loose or uneven film
Cause: Insufficient wrapping tension, too few overlap revolutions, or film not properly pre-stretched.
Solution: Increase film tension setting. Add 1-2 extra overlap revolutions. Verify pre-stretch carriage functioning. Ensure coil is properly centered. Verify film roll loaded properly. Adjust ring speed for consistent wrapping.
