Executive summary Upending and wrapping slit coils on one line saves a crane lift between the two steps. Our line in this video lifts each slit coil from horizontal to vertical, wraps it through the eye with a white band of material and sends it on along the conveyor. Film per coil follows from the wraps round the coil times the section perimeter.

What the video shows
A slit coil arrives on the conveyor of our blue-framed line. The upper unit lifts the coil and turns it from horizontal to vertical.
The wrapping unit then wraps a white band through the eye and round the coil section. The wrapped coil carries on along the conveyor to the next step. A control cabinet with a touchscreen, a green light and a red button stands at the right. Yellow warning triangles are on the machine guard and the cabinet, yellow lines mark the floor, and FHOPE PACKING SOLUTION FOR YOU is marked on the blue frame.
How a coil goes through the line
| Step | What happens |
|---|---|
| Infeed | The coil arrives on the conveyor |
| Upend | The upper unit turns the coil from horizontal to vertical |
| Wrap | A band is wrapped through the eye and round the section |
| Outfeed | The wrapped coil moves on along the conveyor |
Upending and wrapping on one line means the coil is not moved between separate machines.
Film per coil
Illustrative example:
| Item | Value |
|---|---|
| Outer and inner diameter (illustrative) | 1,000 and 508 mm |
| Slit width (illustrative) | 150 mm |
| Coil wall, (1,000 − 508) ÷ 2 | 246 mm |
| Section perimeter, 2 × (246 + 150) | 792 mm |
| Mean circumference, π × 0.754 m | about 2.37 m |
| Advance per wrap (illustrative) | 50 mm |
| Wraps, 2,370 ÷ 50 | about 47 |
| Film laid, 47 × 0.792 m | about 37.2 m |
A smaller advance per wrap gives more overlap and more film per coil.
Controls and safety
The upending unit lifts and turns a full coil, and the wrapping unit runs through the coil eye. Keep people outside the yellow floor lines 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 slit coil upending and wrapping line
- Coil outer and inner diameter and slit width range.
- Heaviest coil.
- Wrap material and overlap.
- Coil orientation needed after wrapping.
- Coils per shift.
- Line layout before and after.
Engineering FAQ
Q: What does the line do? A: It upends slit coils from horizontal to vertical and wraps them through the eye.
Q: How much film does a coil take? A: Wraps times section perimeter: 47 × 0.792 m gives about 37.2 m in our example.
Q: How many wraps go round a coil? A: Mean circumference over advance per wrap: 2,370 ÷ 50 mm gives about 47.
Q: Where are the controls? A: On a cabinet at the right with a touchscreen, a green light and a red button.
Q: Can it take my slit widths? A: Send the width range and coil diameters and we set the upender and wrapper.
Next step
We plan your slit coil upending and wrapping line in three steps:
- Submit your layout drawing with coil diameters, widths and weights to info@fhopepack.com.
- Receive a proposal within 48 hours, with wrap material and overlap.
- Book a site survey to check coils per shift and line layout.
