Executive summary Stainless steel coils show every scratch, so they need a film cover and careful handling from the line to the pallet. Our machines in this video wrap each coil in film on a roller conveyor, and a stacker with a gripping arm then sets the wrapped coils on a wooden pallet. Film passes follow from the coil OD and the film overlap. We set both per project.

What the video shows
The video shows several of our coil wrapping machines in turn. On each, a coil lies flat on the roller conveyor while a wrapping head above it lays film round the coil as it turns, building up the cover layer by layer. A worker in an orange hard hat stands beside the first machine, and small inset views show other machines running.
Later a light green upright stacker with a yellow arm and gripper picks up a wrapped coil and lowers it onto a stack on a wooden pallet, then returns for the next one. Yellow railings with black and yellow stripes surround the stacker, and our FHOPE name is on the wrapping head.
How the wrap and stack line works
| Step | What happens |
|---|---|
| Infeed | The coil runs in flat on the roller conveyor |
| Wrap | The head lays film round the turning coil |
| Convey | The wrapped coil moves on to the stacker |
| Stack | The gripper sets it on the pallet stack |
| Out | The full pallet is taken away |
No one lifts or slides a coil by hand between wrapping and the pallet, which is where most surface marks start. For the station itself, see our steel coil packing station overview.
Film passes and overlap per coil
We count passes at the OD, where overlap is lowest. Illustrative example:
| Item | Value |
|---|---|
| Coil OD (illustrative) | 1,200 mm |
| Circumference, π × 1,200 | about 3,770 mm |
| Film width (illustrative) | 150 mm |
| Advance per pass at 50% overlap | 75 mm |
| Passes, 3,770 ÷ 75 | about 50 |
The eye always gets more overlap than the OD, so the whole coil gets at least 50%.
Coils per pallet
| Item | Value |
|---|---|
| Coil width (illustrative) | 300 mm |
| Coils per stack (illustrative) | 4 |
| Stack height, 4 × 300 | 1,200 mm |
| Coil weight (illustrative) | 800 kg |
| Load per pallet, 4 × 800 | 3,200 kg |
We check the pallet, forklift and truck limits before we set the stack height.
Controls and safety
The coil turns under the wrapping head and the stacker swings full coils over the pallet. Keep people outside the railings while the line runs, and enter only with it stopped and isolated.
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 coil wrapping and stacking line
- Coil OD, ID, width and weight range.
- Surface finish and film layers.
- Coils per hour.
- Stack height and pallet size.
- Labels or marking you need.
- Floor space and line layout.
Engineering FAQ
Q: How many passes does a coil need? A: About 50 for a 1,200 mm OD coil with 150 mm film at 50% overlap in our example.
Q: Where is overlap counted? A: At the OD, where it is lowest; the eye always gets more.
Q: Why stack by machine instead of by hand? A: Lifting or sliding coils by hand is where most surface marks start.
Q: How are wrapped coils stacked? A: An upright stacker with a gripper sets each coil on the pallet stack.
Q: How heavy is a full pallet? A: Coil weight times coils per stack, within your pallet and forklift rating: 3,200 kg for four 800 kg coils in our example.
Q: Is the stacker guarded? A: Yes. Yellow railings surround it.
Next step
We plan your coil wrapping and stacking line in three steps:
- Submit your layout drawing with coil sizes, finish and output to info@fhopepack.com.
- Receive a proposal within 48 hours, with the film and stacking plan.
- Book a site survey to check the pallet and line layout.
