Executive summary This clip shows one of our steel wire lines. Wire from the take-up machines is laid in rings into a cage to form a coil, the coil moves on rollers to the wrapping station, and a ring wraps film through the coil eye. The wrapper matches our FPW-AU300, which takes coils of 300–1,500 kg and 500–1,200 mm OD. Below we cover the stages, why they run in one line, the data and a worked example for turns per coil.

What the clip shows
The clip follows steel wire from the take-up machines to a wrapped coil in one of our wire lines.
| Stage | What you see |
|---|---|
| Take-up | A row of blue take-up machines with overhead wire guides feeds wire into the line |
| Rewinding | Close-ups show a rotating laying head that drops the wire in rings into a cage below, forming the coil |
| Control | Grey cabinets with touch-screen panels sit beside each rewinding station |
| Transfer | The finished coil leaves the station and moves along a roller conveyor |
| Wrapping | The coil lies flat on rollers between upright guide rollers while a ring passes film through the coil eye |
| Result | The last frames show the coil covered in yellow film |
Why rewinding and wrapping run in one line
- No double handling. The coil goes from the rewinding cage to the wrapper on conveyors, so no crane or forklift lifts it in between.
- Steady coil. The upright guide rollers hold the flat coil in place while the ring turns.
- Matched pace. Each rewinding station feeds the same wrapper, so the wrapper is sized to the combined coil rate.
- Clean surface. The film covers the wire before it is stored or shipped.
FPW-AU300 data
The wrapping station matches our automatic steel wire coil packing machine FPW-AU300. Our published data:
| Item | Published value |
|---|---|
| Coil weight | 300–1,500 kg |
| Coil width | 100–300 mm |
| Coil OD | 500–1,200 mm |
| Coil ID | 300–900 mm |
| OD minus ID | Under 500 mm |
| Roller speed | 2–4 m/min |
| Ring speed | 0–90 r/min |
| Overlap | 10–90% |
| Wrap material | Stretch film or paper, 120 mm wide, 50 mm core |
| Power | About 3.8 kW, 380 V 50 Hz 3-phase |
Rewinding stations are built to the wire size and coil weight of each line, so their data is set per project.
Turns per coil
Worked example (illustrative). With 120 mm film at 50% overlap, each turn advances 120 × 0.5 = 60 mm round the coil. A coil of 1,000 mm OD and 600 mm ID has a mean diameter of 800 mm, so its centre line is about π × 800 ≈ 2,513 mm round. That needs about 2,513 ÷ 60 ≈ 42 ring turns for one full cover. Roller speed and ring speed are set together to hold this pitch.
Selection checklist
- Wire diameter and grade.
- Coil weight, OD, ID and width.
- Number of rewinding stations feeding the wrapper.
- Film or paper, and overlap.
- Coils per hour.
- Labelling, weighing or stacking after wrapping, as in our steel wire coil wrapping, upending and stacking line.
Safety
- Keep clear of the laying head and the cage while the wire runs.
- Guard the wrapping ring and stop it before reaching in.
- Lock out the conveyor before clearing a coil.
- For CE markets, the line is designed to ISO 12100 and EN 415-10.
Engineering FAQ
Q: What does this line do? A: It rewinds steel wire into coils and wraps each coil in film through the coil eye.
Q: What overlap can be set? A: 10–90% on the FPW-AU300; 50% is used in the worked example.
Q: How does the coil reach the wrapper? A: On roller conveyors from the rewinding station, with no crane in between.
Q: What coil sizes does the wrapper take? A: OD 500–1,200 mm, ID 300–900 mm and width 100–300 mm on our FPW-AU300 data.
Q: How heavy can the coil be? A: 300–1,500 kg on the FPW-AU300.
Q: How many ring turns cover a coil? A: About 42 turns for a 1,000 mm OD, 600 mm ID coil with 120 mm film at 50% overlap.
Q: Can paper be used instead of film? A: Yes. The FPW-AU300 takes stretch film or paper, 120 mm wide.
Q: Which standards apply? A: For CE markets, ISO 12100 and EN 415-10.
Next step
We size a wire coil rewinding and packing line in three steps:
