Executive summary A through-the-eye coil wrapper runs stretch film through the centre of a pipe coil and round its outside as the coil turns, so every face is covered. Our FPH-200 coil wrapper takes coils up to 900 mm OD and 50 kg, at 15 to 35 s per coil.

What the machine does
The wrapper is a compact vertical ring unit: a PE-RT pipe coil is guided into the ring frame, and film lays onto the pipe turns as the coil passes the ring. The film covers the outer turns, the bore side and both coil faces in one continuous action.
A product tag placed on the coil before the wrap sits under the film as it lays on, so the tag stays readable and cannot fall off. At the ring side, the film roll carriage feeds the film and an indicator shows the machine state. Where an operator guides the coil by hand, the wrap window runs longer than the quoted 15 to 35 s per coil, because loading and guiding take place at the same station.
Cycle time per coil
The specified wrapping time is 15 to 35 s per coil. The effective station cycle is the wrap time plus coil loading, tagging and unloading, so the layout of the operator station decides how close the line runs to the specified range.
How through-the-eye coil wrapping works
The coil stands on supportive guide rollers, and the wrapping ring passes through the coil eye. Each ring turn carries the film roll through the centre and around the outside, so the film covers the inner and outer turns and both faces in one pass.
The guide rollers turn the coil so the wrap moves round it. The overlap comes from the ring speed against the roller speed, both set by inverters, and can be set from 20% to 90%. A brake on the film roll sets the tension. Close overlap gives a sealed cover that keeps dust off the pipe in storage.
| Part | What it does |
|---|---|
| Wrapping ring | Carries the film through the coil eye |
| Film roll on the carriage | Feeds the film under brake tension |
| Supportive guide rollers | Hold and turn the coil |
| Inverters | Set ring and roller speeds |
| Alarm indicator | Shows the error when trouble occurs |

FPH-200 coil wrapper specifications
| FPH-200 coil wrapper | Specification |
|---|---|
| Coil ID | 300 to 600 mm |
| Coil OD | 400 to 900 mm |
| Coil width | 50 to 200 mm |
| Coil weight | 5 to 50 kg |
| Ring speed | 20 to 90 r/min |
| Wrapping time | 15 to 35 s per coil |
| Overlap | 20% to 90% |
| Packing material | LLDPE, PE, stretch film or PVC |
| Power | 1.5 kW, 380 V, 50 Hz |
The machine runs in manual or automatic mode, and an original reset positioning system returns the ring to its start point after each wrap.
Takt check
For an illustrative PE-RT extrusion line that delivers one coil every 90 s, the takt is 90 s per coil. A wrap of 15 to 35 s leaves 55 to 75 s to load, tag and unload the coil.
That suits one operator at the wrapper. If the line makes a coil every 40 s, a 35 s wrap leaves only 5 s, so we lower the overlap or add conveyors.
Selection checklist for a PE pipe coil wrapper
- Coil ID and OD, against 300 to 600 mm and 400 to 900 mm.
- Coil width and weight, against 50 to 200 mm and 5 to 50 kg.
- Film type and overlap for storage.
- Tag or label placed before the wrap.
- Coils per hour, against 15 to 35 s per wrap.
Controls and safety
Where the operator guides the coil by hand beside the ring frame, a hand on a turning coil next to the ring is the move to design out. We let the guide rollers hold the coil and keep the operator outside the ring frame once the wrap starts.
Stop, isolate and lock out the wrapper before anyone threads film, places a tag on a coil in the ring or frees a coil that has stuck. The alarm indicator shows a fault, and manual mode is for set-up only.
The standards that apply depend on the destination market. For CE markets, ISO 12100 sets the risk-assessment method, and EN 415-10 covers general requirements for packaging machines, which fixes guarding and the stop arrangement.
Engineering FAQ
Q: Why wrap PE pipe coils through the eye? A: The film covers the inner and outer turns and both faces, so the coil is sealed against dust.
Q: Can a product tag go under the film? A: Yes. A tag placed on the coil before wrapping is held under the film.
Q: What coils fit the FPH-200? A: Coils of 300 to 600 mm ID, 400 to 900 mm OD, 50 to 200 mm wide and 5 to 50 kg.
Next step
We size a PE pipe coil wrapping machine in three steps:
- Submit your layout drawing with the coil sizes, weights and line output, to info@fhopepack.com.
- Receive a proposal within 48 hours, with the wrapper model, the film plan and the cycle check.
- Book a site survey so we confirm the extrusion line, the tagging step and the guarded ring area.
