Executive Summary Heavy industrial coils require reliable protective packaging without unnecessary material handling. In this horizontal coil wrapping configuration, the coil rests on a heavy-duty roller saddle while a motorized orbital ring passes protective film through the coil eye. Motorized saddle rollers rotate the coil to ensure complete 360° circumferential coverage. By designing the wrapping station to travel on rails directly to the stationary coil, heavy loads do not need to be repositioned between loading and wrapping cycles. Coils can be wrapped with various protective stretch films, with film specifications and colors tailored to specific storage and transport requirements.

What the machine does
| Step | Operation |
|---|---|
| Loading | The coil is placed onto the motorized roller saddle. |
| Station Alignment | The ring wrapping station travels along linear guides to the coil location. |
| Wrapping | Protective film passes through the coil eye as saddle rollers rotate the coil. |
| Film Application | Stretch film is applied per specification; film color and type are set per coil. |
| Unloading | The fully wrapped coil is lifted off the roller saddle. |
Why a movable station
- Heavy coils stay put: The wrapping station travels directly to the workpiece, eliminating dangerous and costly re-handling of heavy metal coils.
- Easy loading: The station retracts clear of the saddle area, allowing unobstructed overhead crane or forklift loading.
- Full 360° coverage: Motorized saddle rollers turn the coil at a synchronized speed while the orbital ring dispenses film through the eye.
- One saddle, many sizes: The saddle roller geometry and ring opening accommodate a wide range of coil diameters and face widths.
- Orbital wrapper baseline: In heavy-duty horizontal orbital wrapping systems, ring rotation speeds typically operate between 10–60 r/min with linear wrapping speeds of 4–15 m/min [manufacturer rating].
Film turns per coil
Worked example (illustrative).
| Item | Value |
|---|---|
| Coil outer diameter (illustrative) | 1,500 mm |
| Outer circumference, 3.14 × 1,500 | 4,710 mm |
| Film width (illustrative) | 100 mm |
| Overlap (illustrative) | 50% |
| Ring turns per coil revolution, 4,710 ÷ 50 | about 94 |
(Note: The above calculation uses illustrative baseline values. Actual film consumption varies based on applied film pre-stretch ratio and specific coil dimensions.)
What we set per coil
| Setting | Depends on |
|---|---|
| Ring size | Coil outer diameter (OD), inner diameter (ID), and width |
| Saddle | Coil diameter and weight capacity |
| Overlap | Protection level required (10%–90% adjustable [manufacturer rating]) |
| Film | Material type (LLDPE, PE, PVC, VCI, or Paper; width 300/500 mm) and film color [manufacturer rating] |
Selection checklist
- Coil outer diameter (OD) and inner diameter (ID).
- Coil width / stack height.
- Maximum coil weight.
- Target throughput (coils per hour).
- Material preference (stretch film, VCI film, or kraft paper).
- Loading method (overhead crane or heavy-duty forklift).
Safety
- Keep clear of moving station pathways while linear movement is active.
- Stay outside the safety enclosure or perimeter fence while the line is in operation.
- Perform Lockout/Tagout (LOTO) procedures before clearing any material obstruction or performing maintenance.
- Equipment is built with safety guardrails and closed structure designs, featuring adjustable film tension controls [manufacturer rating].
- For CE markets, the machine design complies with ISO 12100:2010 (safety of machinery) and EN 415-10:2014 (safety of packaging machines).
Engineering FAQ
Q: What is a movable wrapping station? A: A motorized orbital ring assembly that travels along floor rails directly to the coil, eliminating the need to shift heavy coils into a fixed wrapping zone.
Q: How is film passed through the eye? A: The rotating ring carries the film carriage through the center eye of the coil while motorized saddle rollers rotate the coil around its horizontal axis.
Q: How many ring turns does a coil need? A: Approximately 94 ring turns for a 1,500 mm outer diameter coil at 50% overlap using 100 mm wide film, as shown in the illustrative worked example.
Q: Can colored or specialized film be used? A: Yes, film types and colors (such as transparent, white, blue, or anti-corrosion VCI film) are specified based on coil storage and protection requirements.
Q: How are heavy coils loaded onto the machine? A: Coils are positioned directly onto the roller saddle using an overhead crane with C-hook/tong or a heavy-duty forklift.
Q: Which international safety standards apply? A: For European and CE-regulated markets, machines are engineered to ISO 12100:2010 and EN 415-10:2014 standards.
