Overview
A master coil wrapper seals large steel coils in film so the bright surface stays protected through storage and transit. The family runs an eye-through (orbital) wrapping cycle inside a fenced safety cell: a ring carrying the film roll passes through the coil eye while rollers turn the coil, so the full section — inner face, bore and outer face — is covered with no open edge. The footage shows the coil arriving on a conveyor and leaving sealed in film after passing through the wrapping ring. This page is for steel mills, coil service centres and logistics teams that pack master coils; it covers the conveyor-fed cycle, wrapper sizing and edge protection.
The Conveyor-Fed Eye-Through Cycle
In eye-through wrapping the coil stays on its axis while a ring turns around it. Two blocker-roller stations hold and slowly rotate the coil; as the ring passes through the eye, each pass lays one film width across the section, so it is covered inside and out with no open edge. Overlap is set in the program, so every coil of a type is wrapped identically — no hand wrapping a coil that can weigh several tonnes.
On the machine in the footage the cell sits on a roller conveyor: the coil rides in, is wrapped by the ring, and continues out of the cell. A mesh fence with a gate keeps operators outside while the cycle runs. Conveyor height, fence line and gate-and-stop logic are confirmed per project.
| Stage | What happens |
|---|---|
| Infeed | Coil arrives on the roller conveyor inside the fenced cell |
| Wrap | Blocker rollers turn the coil; the ring passes through the eye and lays film across the section |
| Hold | Coil is rotated through the ring until the programmed overlap is reached |
| Outfeed | Wrapped coil continues on the conveyor and leaves the cell |
What the Footage Shows
The footage, filmed from outside the fence, follows one conveyor-fed cycle: the bare-steel coil travels into the wrapping ring, and the ring — with its film carriage — turns through the coil eye, laying film around the section in repeated passes until the coil is fully covered at the exit side. The view is partly blocked by fence posts, so coil size and number of wraps are not read from the footage.
The machine title mentions corner protection, but the corner-protector station is not shown in this clip. Corner or edge protectors are a configurable part of a master-coil line: fitted to the outer and inner edges before the final wrap so the film holds them, on a separate station ahead of the ring. Tell us which edges need protection and the station is confirmed per project.
Wrapper Sizing by Coil Range
The wrapper is sized from coil ID, OD and width, the maximum coil weight and the loading method. The family covers conveyor-fed and crane-loaded layouts; the figures below are indicative starting points from the current product material and are confirmed for the actual coil range in the proposal:
| Model | Coil ID | Coil OD | Coil width | Max weight | Loading |
|---|---|---|---|---|---|
| FPCA-1000 | 508 / 610 mm | 700–1600 mm | 20–400 mm | 2000 kg | Conveyor |
| FPCA-1200 | 508–610 mm | 800–1400 mm | 20–500 mm | 2500 kg | Conveyor |
| FPS-2000 | 508 / 810 mm | 700–2500 mm | 600–2500 mm | 10000 kg | Crane |
Conveyor-fed models such as the FPCA-1000 and FPCA-1200 match the roller-conveyor cell for narrower coils; wide, heavy master coils move to crane loading, as on the FPS-2000. Each wrapper is built to the project’s coil range.
Wrap Materials and Edge Protection
Wrap materials include stretch film, kraft paper, woven fabric and VCI film.
| Material | Typical use |
|---|---|
| Stretch film | Dust and moisture barrier; see-through |
| Kraft paper | Surface protection for bright or polished coils |
| Woven fabric | Tougher outer layer for rough handling |
| VCI film | Corrosion protection on export coils |
Film alone does not stop a dent: coil edges take knocks from forks, crane hooks and lashing, so corner or edge protectors spread the contact load before the final wrap. For CE markets, a risk assessment to ISO 12100 and the general packaging-machine requirements of EN 415-10 are typically referenced, with the cell fence-and-gate arrangement fixed per project. As a stated manufacturer practice for this machinery family, each unit goes through sustained functional and safety testing before delivery (about 24 hours where stated), including the control system and the emergency-stop function.
FAQ
Q: Does the footage show corner protectors being placed?
A: No. It shows the eye-through wrapping cycle; edge protection is a separate station ahead of the ring, specified per project.
Q: How is the coil fed through the wrapper?
A: In the footage the coil rides in on a roller conveyor, is wrapped by the ring, and continues out of the cell; the FPCA conveyor models are built for this feed.
Q: What is the largest coil these wrappers take?
A: The model table lists the FPS-2000 for coils up to about 2500 mm OD, 2500 mm width and 10000 kg, loaded by crane.
Q: Can the same machine apply paper and film?
A: Yes. Stretch film, kraft paper, woven fabric and VCI film can be specified, and the carriage is set for the materials you name per project.
Q: Why is the wrapper inside a fence?
A: The ring and the turning coil are moving hazards; the fence and gate keep people out while the cycle runs, and the gate-and-stop logic is fixed in the risk assessment.
