Executive summary Drawn wire feeds continuously from the drawing machine into an automatic coiler, which forms dense, uniform coils before transferring them to downstream roller conveyors. The line conveys each coil directly into an eye-through orbital wrapping station that applies protective film through the core and around the outer circumference. Wrapping immediately after coiling shields fresh wire from airborne moisture and contaminants before storage or transit.

How the line runs
| Step | What happens |
|---|---|
| Coiling | The coiler receives drawn wire from the drawing line, regulates tension via servo drive to form a neat coil, and counts length to trigger cutoff [manufacturer rating]. |
| Transfer & Strapping (Optional) | Formed coils are clamped and transferred onto roller conveyors; optional radial strapping can be integrated prior to wrapping [manufacturer rating]. |
| Conveying | Heavy-duty powered roller conveyors advance each coil toward the orbital wrapping station. |
| Eye-through Wrapping | The wrapping station shuttles film through the coil eye, applying protective film with pneumatic cut-and-clamp action [manufacturer rating]. |
| Outfeed | Fully wrapped, moisture-protected wire coils exit the conveyor for crane pick-up or palletizing. |
| Line Integration | Automated stations along the conveyor interlock through a centralized PLC system to synchronize speeds. |
Why wrap straight after coiling
- Clean wire. Applying film immediately seals out industrial dust, mill scale, and airborne particulates before surface contamination can take hold.
- Dry wire. Immediate packaging traps ambient dryness and prevents flash rusting during warehouse storage or maritime shipment.
- No waiting. Coils move seamlessly from the coiler to the wrapping ring without intermediate buffer staging, eliminating floor clutter.
- Colour coding. Film colour can mark wire grade, alloy type, or batch traceability across processing facilities.
- Packaging versatility. The wrapping unit supports stretch film, PE, LLDPE, HLDPE, non-woven fabric, and sackcloth tape depending on corrosion protection requirements [manufacturer rating].
Coil sizes and pace
Worked example (illustrative).
| Item | Value |
|---|---|
| Coil OD (illustrative) | 800 mm |
| Coil ID (illustrative) | 500 mm |
| Coil height (illustrative) | 400 mm |
| Coils per hour (illustrative) | 40 |
| Film overlap (illustrative) | 50% |
| Time per coil at the wrapper, 3,600 ÷ 40 | 90 s |
The wrapper ring opening and shuttle diameter are selected to match the maximum coil envelope, with adjustable ring center height to maintain balanced wrap coverage across both small and large outer diameters [manufacturer rating].
What we set per coil
| Setting | Depends on |
|---|---|
| Machine and ring size | Chosen for the largest coil dimensions across the plant schedule; ring center position adjusts to suit varying OD ranges [manufacturer rating]. |
| Film selection | Selected by protection requirements: stretch film, PE, non-woven, or woven tape [manufacturer rating]. |
| Overlap percentage | Storage duration and shipping severity; overlap can be set between 10% and 90% via the operator touch panel [manufacturer rating]. |
| Tension control | Wire hardness and coil sensitivity, regulated by mechanical/electromagnetic brake on the film carriage [manufacturer rating]. |
| Conveyor index pace | Matched to drawing machine cycle rate and upstream coiler cycle time. |
Selection checklist
- Wire diameter range and incoming line speed (m/min).
- Coil outer diameter (OD), inner diameter (ID), height range, and maximum weight.
- Packaging material specification (stretch film, PE, woven cloth) and layer requirements.
- Required line throughput (coils per hour).
- Upstream strapping requirement (whether radial strapping is required before stretch wrapping).
- Floor layout dimensions between drawing machine outfeed and warehouse bay.
Safety
- Keep clear of rotating orbital rings and moving carriage stations during operation.
- Stay outside the perimeter safety fencing while the automatic line is energized.
- Lock out and tag out (LOTO) electrical and pneumatic supplies before clearing wire jams or servicing the wrapper.
- For CE markets, the complete machinery line conforms to ISO 12100:2010 risk reduction principles and EN 415-10:2014 safety requirements for wrapping machines.
Engineering FAQ
Q: What does the automated wire drawing and packing line do? A: It takes continuous drawn wire directly from the drawing block, coils it into uniform coil dimensions, and delivers it through an eye-through orbital wrapper to seal every coil in protective film.
Q: Why wrap right after coiling? A: Freshly drawn wire is clean and dry. Wrapping immediately eliminates exposure to workshop humidity, prevents oxidation, and keeps surface finishes free of particulate dust.
Q: Can film colour and type vary? A: Yes. Operators can switch between different film colours to designate wire grades, or deploy barrier materials such as PE, stretch film, or woven tape [manufacturer rating].
Q: Can automated strapping be integrated before wrapping? A: Yes. An automatic wire coil strapping unit can be positioned ahead of the wrapping ring to strap through the core prior to film application [manufacturer rating].
Q: What sets the line speed? A: Overall throughput is governed by the coils per hour exiting the upstream drawing machine, with wrapper cycle times adjusted via PLC to eliminate line bottlenecks.
Q: Which design standards apply? A: Lines supplied to CE jurisdictions comply with ISO 12100:2010 for machinery risk evaluation and EN 415-10:2014 for automated wrapping machine safety.
