Executive summary This clip shows our turnstile strapping machine at the exit of a slitting line. The slit coils hang side by side on a turnstile arm, and a strapping head on a yellow frame straps each coil before it leaves the arm. Strapping on the arm keeps narrow coils from springing open before packing. The machine feeds our slitting coil packaging line, which handles coils from 30 kg to 4,000 kg with 300, 508 or 610 mm ID.

What the clip shows
The footage shows our turnstile strapping machine at the slitting line exit.
| Step | What you see |
|---|---|
| Arm load | A row of dark slit coils hangs side by side on the turnstile arm |
| Strapping head | A strapping head on a yellow frame sits beside the arm, level with the coils |
| Second load | A second arm load of bright slit coils moves into the strapping position |
| Strapping | The head works along the row while the coils stay on the arm |
| Result | The strapped coils stay tight on the arm, ready for the next station |
Strapping the coils on the arm means each narrow coil is closed before it is lifted or tilted.
Why strap on the turnstile arm
- No spring-back. Narrow slit coils can loosen once they leave the slitter; a strap on the arm holds the outer wrap.
- No extra handling. The coils are strapped where they already hang, so there is no separate strapping station before the downender.
- Safer work. Operators stay out of the area between the arm and the head instead of strapping coils by hand.
- Steady takt. The turnstile turns the next arm load into place while the strapped load moves on.
Slit coil line data
The turnstile strapper feeds our slitting coil packaging line. Our published data for that line:
| Item | Published value |
|---|---|
| Coil weight | 30–4,000 kg (narrow coils) |
| Coil OD | 500–1,500 mm, extendable to 2,100 mm |
| Coil ID | 300 / 508 / 610 mm |
| Slit width | 8–500 mm (narrow coils) |
| Packing speed | 20–40 coils per hour (narrow coils) |
| Strap | PET or steel strap |
| Line stations | Turnstile and downender, strapping, wrapping, weighing and labelling, stacking |
| Control | Siemens S7-1200 / S7-1500F |
Each line is customized, so the arm length, strap type and stations are matched to your slitting line.
Straps per arm load
Worked example (illustrative). A 1,250 mm wide master coil slit into strips of 125 mm gives 1,250 ÷ 125 = 10 coils on the arm. With 2 straps per coil the head applies 10 × 2 = 20 straps per arm load. The strap count per coil and the number of strips set how long one arm load takes.
Selection checklist
- Master coil width and the slit widths you run.
- Coil weight, OD and ID.
- Number of arms on your turnstile.
- Straps per coil, PET or steel strap.
- Coils per hour from the slitting line.
- Downstream stations: downender, wrapping, weighing, stacking.
Safety
- Keep clear of the turnstile while it turns.
- Keep hands away from the strapping head and strap path.
- Stop the turnstile before clearing a strap jam.
- For CE markets, the line is designed to ISO 12100 and EN 415-10.
Engineering FAQ
Q: What does a turnstile strapping machine do? A: It straps slit coils while they hang on the turnstile arm, before they move to packing.
Q: Why strap before the downender? A: Narrow coils can spring open when handled; a strap on the arm holds the outer wrap first.
Q: What coil sizes does the line take? A: 30–4,000 kg, slit width 8–500 mm, ID 300, 508 or 610 mm and OD 500–1,500 mm (extendable to 2,100 mm), on our published data for narrow coils.
Q: How many coils per hour? A: 20–40 coils per hour for narrow coils, on our published line data.
Q: Which strap can it use? A: PET or steel strap.
Q: How many straps per arm load? A: It depends on the slit count and straps per coil; 10 coils with 2 straps each take 20 straps in the worked example.
Q: Which control system runs the line? A: A Siemens S7-1200 or S7-1500F PLC.
Q: Which standards apply? A: For CE markets, ISO 12100 and EN 415-10.
