Sintesi
A wire wrapping machine, more precisely a wire coil wrapping machine, packs a steel wire or copper wire coil by passing a ring of film, paper or woven tape through the coil eye while the coil turns on rollers. The wrap seals out dust and moisture and holds loose turns in place. Our FPW-300 takes wire coils of 10–250 kg, OD 450–850 mm and width 100–300 mm. Heavier or thin-gauge copper coils move to the horizontal FPC-300.
On the upright design, a copper wire coil stands on drive rollers while the ring carries blue woven tape through the eye. A yellow guard frame encloses the wrapping zone. Steel wire coils run on the same machine. A related macchina avvolgitrice per bobine di filo uses the same eye-through principle.

Why steel and copper wire coils are wrapped
Wire coils travel and sit in storage for weeks. Steel wire rusts when moisture reaches it, and copper wire tarnishes and marks easily. A full eye-through wrap closes the coil against dust, air and moisture. It also keeps the outer turns from loosening when the coil is handled by crane or forklift.
How eye-through wrapping works
The coil stands on powered support rollers that turn it slowly, positioned so the wrapping ring runs through the coil eye. The ring rotates and lays the packing material around the coil section. Each ring turn covers one band of the coil, and the coil rotation moves the next band under the ring. The overlap between bands is set to the requirement.
The ring height is adjusted for different coil ODs. A brake on the tape release stops the material from folding. The operator enters coil OD, ID, width, weight range and ring speed at the panel, and the machine runs in manual or automatic mode.
Steel wire vs copper wire: what changes
| punto | Steel wire coil | Bobina di filo di rame |
|---|---|---|
| Rischio principale | Rust from moisture | Tarnish and surface marks |
| Materiale tipico | Stretch film, compound paper or woven belt | Woven tape, paper or stretch film |
| Manovrabilità | Robust; upright wrapping on rollers works well | Soft; heavy or thin-gauge coils need full support |
| Confezionatrici Verticali VFFS | FPW-300 (upright) | FPW-300 for light wire coils; FPC-300 (horizontal) for heavier or narrow strip coils |
Copper is soft. A heavy copper coil standing on two rollers bears its weight on a short arc and can deform. The horizontal FPC-300 lays the coil flat on a conveyor, so the full face is supported. It wraps copper strip as narrow as 8 mm without bending it.
FPW-300 and FPC-300 data

Worked example: will the coil fit?
Take a wire coil with OD 700 mm, ID 450 mm and width 100 mm, wrapped with 100 mm tape at 50% overlap. The weight below treats the coil as solid metal, so it is an upper bound; a wound wire coil weighs less.
| step | Calcolo | Risultato |
|---|---|---|
| Ring face area | π/4 × (0.70² − 0.45²) | 0.226 m² |
| Volume | 0.226 × 0.10 | 0.0226 m³ |
| Steel, upper bound | 0.0226 × 7,850 | circa 177 kg |
| Copper, upper bound | 0.0226 × 8,960 | circa 202 kg |
| Fits FPW-300? | 10–250 kg, OD 450–850, ID 300–700, width 100–300 | sì |
| Mean circumference | π × (700 + 450) ÷ 2 | circa 1,806 millimetri |
| Avanzamento per giro dell'anello | 100 mm × 50% | 50 mm |
| L'anello gira | 1,806 50 ÷ | circa 36 |
| perimetro della sezione | 2 × (125 + 100) | 450 mm |
| Nastro per bobina | 36 × 0.45 m | circa 16 m |
Risultato. Both the steel and the copper version fit the FPW-300. The coil needs about 36 ring turns and 16 m of tape. Wrap time is ring turns divided by ring speed. Total cycle time is loading, plus wrap time, plus clamping and cutting the tape tail, plus unloading. For example, 36 ring turns at 60 r/min take 36 s of wrapping before handling is added. The ring speed range and loading method are confirmed at quote with your output target.
Lista di controllo per la selezione
- Wire material: steel, copper or other.
- Intervallo di peso, diametro esterno, diametro interno e larghezza della bobina.
- Packing material and overlap.
- Bobine all'ora.
- Loading: crane, forklift or conveyor.
- Labelling or strapping after wrapping.
Sicurezza: EN 415-10 e ISO 12100
The wrapper is assessed to ISO 12100 and built to the packaging machine safety series EN 415-10. A guard frame closes the ring zone, and the E-stop is on the panel. Guarding is set for each layout.
FAQ di ingegneria
Q: Can one machine wrap both steel wire and copper wire? A: Yes, within the FPW-300 range of 10–250 kg. Heavier or narrow copper coils go to the horizontal FPC-300.
Q: Which material protects best against rust? A: A full eye-through wrap in stretch film or compound paper seals the coil. The choice depends on storage time and climate.
Q: Can the overlap be changed? A: Yes. The overlap is set to the requirement at the panel.
Q: What power does the FPW-300 need? A: 1.5 kW at 380 V 50 Hz 3 phase.
