Descriere
Very long, large-cross-section products — pipes, tubes, profiles and long bundle loads — are difficult to wrap on a conventional machine because the load cannot turn. A giant horizontal orbital stretch wrapping machine solves this with a large ring that rotates around the load while the product is fed axially through it, applying stretch film in a continuous spiral along the full length. The machine shown is built at a scale where the orbital ring spans several meters and is fitted with a film covering unit that lays a covering film over the load faces before or during the wrap, giving a closed, even skin. This article explains how the ring and covering unit work together, what ring and film dimensions to confirm, and what to prepare before ordering. It is written for plant managers and packaging engineers handling long and oversized products that are currently wrapped by hand or not wrapped at all.
The video below shows the giant ring wrapping a long load and the film covering unit in operation:
How the Ring and the Film Covering Unit Work Together
The line combines two film operations in one pass: a covering unit ahead of the ring lays a covering film over the load, and the rotating ring then applies spiral stretch film that holds the covering layer down and ties the whole bundle together.
| Stație pentru lacăte | Ce se întâmplă |
|---|---|
| Alimentare | The long load is carried axially toward the machine on the infeed roller line. |
| Unitate de acoperire cu film | A covering film is laid over the top and side faces of the load. |
| Giant orbital ring | The ring rotates around the load while it advances, applying spiral stretch film. |
| Hrănire | The completely wrapped load continues on the outfeed side. |
The covering film closes the top face that a spiral alone does not cover, which matters when the product must arrive with a smooth, closed skin — for sheet, board, panel or long profile bundles. The orbital ring wraps the length continuously as the load passes through, so there is no rotation of the load and no length limit imposed by a turntable.
What to Confirm About Ring and Film Sizes
The practical sizing questions for this machine are about the ring opening and the film widths, because both are set to the project:
| Intrare | Why it decides the build |
|---|---|
| Maximum load width and height | Sets the orbital ring diameter, which spans several meters and is confirmed per project. |
| Lungimea încărcăturii | Confirms the wrap runs the full length as the load passes through. |
| Covering film width | Size to the load width plus the side drop the spiral must catch. |
| Stretch film width and overlap | Sets the number of ring turns per meter and film consumption. |
| Randament pe schimb | Confirms the ring speed and infeed pacing. |
| Floor space and line length | Confirms where the ring and covering unit are installed. |
Because the ring is large and the load passes through it, the machine is designed as part of the line layout: ring diameter, film widths and the distance between the covering unit and the ring are all confirmed per project — state your largest product cross-section and length to the manufacturer.
Siguranță și controale
A ring of several meters moving at wrapping speed is guarded so people stay clear of the rotating ring and the passing load while the line runs; the guard zone is entered only when the machine is stopped and isolated. For CE markets, ISO 12100 sets the risk-assessment method and EN 415-10 sets general requirements for packaging machines; confirm the guarding documentation that applies to your market.
Testare și acceptare în fabrică
Two practice points apply to planning acceptance on this machine family. First, the vendor’s stated practice is to run each machine through non-stop functional and safety testing before delivery — about 24 hours where stated — covering control systems and the emergency-stop function; treat this as the stated family practice, not a single-unit measurement. Second, confirm that the delivered unit includes guarding and safety documentation for your destination market.
FAQ
Q: Why add a film covering unit to an orbital wrapper?
A: The covering film closes the top and side faces of the load, giving a smooth, even skin where a spiral wrap alone would leave the top open.
Q: How large can the ring be?
A: The orbital ring is built to the project’s maximum load cross-section and spans several meters; the exact diameter is confirmed per project.
Q: Does the load rotate or stop during wrapping?
A: Neither — the load passes axially through the stationary ring opening while the ring rotates around it, so there is no length limit from a turntable.
Î: Ce încărcături sunt potrivite pentru această mașină?
A: Long, large-cross-section products — pipes, tubes, profiles, board and panel bundles — that need a closed covering plus a spiral wrap along the full length.
Q: How is film consumption planned?
A: Film use follows from load perimeter, stretch film width, overlap and load length; confirm the widths and overlap with the manufacturer during sizing.
Următorul pas
Send your maximum product width, height and length, throughput per shift, film preferences and floor-space layout to the manufacturer so the ring diameter, covering and film plan are sized and confirmed on the approval drawing.
