Résumé An orbital stretch wrapper turns a ring of film around a long load while rollers feed it through, so a profile many metres long is wrapped as it passes. Our semi-automatic model does this with a blue frame, a guarded ring and white roller tables on both sides, and the operator starts and ends the film by hand. Overlap follows from the vitesse d'avance et la ring speedLes deux sont définis par projet.

Ce que montre la vidéo
A long, flat metal profile lies on the white rollers of the infeed table and runs into our orbital wrapper. The ring sits inside a yellow mesh guard on a blue frame, with a white film roll on its carriage.
The ring turns around the profile as it moves through, and the film spirals along it. A grey control cabinet stands beside the machine, and a second roller table carries the wrapped profile out.
How semi-automatic orbital wrapping works
| Etape | Qui le fait |
|---|---|
| Place the profile on the infeed rollers | Operator or crane |
| Tie the film end to the profile | Opérateur |
| Feed through the turning ring | Machine |
| Cut the film and tuck the tail | Opérateur |
| Lift the wrapped profile off the outfeed | Operator or crane |
The ring and the feed run on their own once started, so the wrap is even along the length. The operator only handles the film at the start and the end.
Film overlap: feed speed vs ring speed
Each ring turn lays one band of film. The load moves forward between turns, so:
Advance per turn = feed speed ÷ ring speed
Illustrative example with 250 mm film at half overlap:
| Produit | Valeur |
|---|---|
| Advance per turn wanted, half of 250 mm | 125 mm |
| Feed speed needed | 125 mm × ring speed in r/min |
| Time for a 6 m profile | 6 m ÷ feed speed |
Slow the feed for more overlap, or speed it up for less. Our emballeuse orbitale à anneau horizontal avec dispositifs de pression uses the same relation on a larger ring. If the ring speed changes, the feed must change with it to keep the same cover.
Film per profile
Illustrative example for a profile bundle 200 mm wide and 100 mm high, 6 m long, at the 125 mm advance above:
| Produit | Valeur |
|---|---|
| Périmètre du faisceau, 2 × (200 + 100) | 600 mm |
| Turns per metre, 1,000 ÷ 125 | 8 |
| Film per metre, 8 × 0.6 m | à propos de 4.8 m |
| Film per 6 m profile, 6 × 4.8 m | à propos de 29 m |
This covers the spiral along the length only. Extra turns at each end, which hold the profile ends, add to it, and the figures are film laid on the load; pre-stretch means the roll pays out less.
Commandes et sécurité
The ring turns at speed inside its yellow mesh guard. Keep hands outside the guard while it runs, and tie or cut the film only when the ring has stopped.
Les normes applicables dépendent du marché de destination. Pour les marchés CE, la norme ISO 12100 définit la méthode d'évaluation des risques et la norme EN 415-10 définit les exigences générales relatives aux machines d'emballage.
Liste de contrôle pour la sélection d'une machine à envelopper orbitale semi-automatique

- Surface au sol et alimentation électrique.
FAQ technique
Q: What does semi-automatic mean here? A: The ring and feed run on their own; the operator starts and ends the film by hand.
Q: How do I set the overlap? A: Advance per turn equals feed speed divided by ring speed. For half overlap on 250 mm film, the feed must advance 125 mm per ring turn.
Q: How much film does a 6 m profile take? A: About 29 m for a 200 × 100 mm bundle at half overlap in our example.
Q: Does the operator guide the profile through the ring? A: No. Once started, the ring and feed run on their own; the operator only fixes the film at the start and cuts it at the end.
Q: Can it wrap single profiles and bundles? A: Yes, as long as the piece passes through the ring and rests on the rollers.
Q: Why roller tables on both sides? A: Long pieces need support in and out, so the profile stays straight through the ring.
