Executive summary A horizontal wrapper wraps film round a load as it passes through a rotating ring, so the load needs support across the gap where the film runs. Our machine in this video carries a boxed load on a green conveyor and a transitional belt through the ring, inside a yellow safety fence. The film overlap follows from the conveyor speed and the ring speed. We set both per project.

What the video shows
A boxed load waits on the transitional conveyor section in the middle of the machine, with a green belt conveyor to the left and a signal tower showing green. To the right, inside the yellow safety fence, sit the film reel and guide rollers.
The load moves into the ring area and clear film comes down over its top, then round its sides as the conveyor carries it on. The wrapped load, with film over four sides, leaves onto the green outfeed belt, and the machine waits for the next one.
How the transitional conveyor works
| Step | What happens |
|---|---|
| Infeed | The load runs in on the green belt conveyor |
| Transition | The transitional belt carries it across the ring gap |
| Wrap | Film from the ring wraps round the load: top, bottom and both sides |
| Outfeed | The wrapped load leaves on the outfeed belt |
The transitional belt keeps the load supported where the film passes, so short loads do not tip into the gap.
Film overlap from conveyor and ring speed
The advance per ring turn is conveyor speed ÷ ring speed. Illustrative example, working back from the overlap you want:
| Item | Value |
|---|---|
| Film width (illustrative) | 250 mm |
| Overlap wanted (illustrative) | 60% |
| Advance per turn, 250 × (1 − 0.6) | 100 mm |
| Conveyor speed needed | 100 mm × ring speed in r/min |
Slowing the conveyor or speeding up the ring raises the overlap. For a ring wrapper with press-down devices, see our horizontal ring orbital stretch wrapping machine; for long rigid sheet goods, see our horizontal orbital ring stretch wrapper for sheet metal building materials.
Loads that need a transitional belt
| Load | Why the belt helps |
|---|---|
| Short boxes | They would tip into the ring gap without support |
| Soft or flexible packs | They need even support under the film |
| Mixed lengths | One belt suits short and long loads |
| Light loads | Film tension does not pull them off line |
Tell us your shortest load, and we size the transitional belt to it.
Controls and safety
The ring turns at speed inside the yellow fence. Keep hands out of the ring area while the machine runs, and clear film or jams only with it stopped.
The standards that apply depend on the destination market. For CE markets, ISO 12100 sets the risk-assessment method and EN 415-10 sets general requirements for packaging machines.
Selection checklist for a horizontal wrapper with transitional conveyor
- Shortest and longest load length.
- Load width and height.
- Loads per hour.
- Film width and overlap.
- Infeed and outfeed conveyor length.
- Floor space and power supply.
Engineering FAQ
Q: How is the advance per ring turn found? A: Divide the conveyor speed by the ring speed; for 100 mm per turn the conveyor must move 100 mm for every ring turn.
Q: What does the transitional conveyor belt do? A: It carries the load across the ring gap so it stays supported while the film wraps it.
Q: How is overlap set? A: By conveyor speed and ring speed. In our illustrative example, 60% overlap on 250 mm film needs a 100 mm advance per ring turn.
Q: How do I raise the overlap? A: Slow the conveyor or speed up the ring.
Q: Which loads need the belt? A: Short, soft, mixed-length or light loads.
Q: Is the ring guarded? A: Yes. A yellow fence surrounds the wrapping area.
Next step
We plan your horizontal wrapping machine in three steps:
- Submit your layout drawing with load sizes and output to info@fhopepack.com.
- Receive a proposal within 48 hours, with the conveyor and film plan.
- Book a site survey to check the line layout and floor space.
