Executive summary This clip shows our rotary arm pallet wrapping machine with a top sheet dispenser in a fenced cell. Sack pallets ride a roller conveyor into the cell, a film top sheet is laid on the load, and the rotary arm wraps the pallet while the load stays still. Wrapped pallets then leave on the conveyor.

What the clip shows
| Step | What you see |
|---|---|
| Infeed | A sack pallet enters on the roller conveyor |
| Top sheet | A film sheet is laid over the load |
| Wrap | The rotary arm turns around the still pallet |
| Outfeed | The wrapped pallet leaves on rollers |
Why a rotary arm and top sheet
- Keeps rain and dust out. The sheet covers the top of the sacks.
- Load stays still. The arm turns, so tall or loose sack pallets are not spun.
- In line. Top sheet and wrap happen in one station.
- Clean top. Film over the sheet holds it in place.
Film turns per pallet
Worked example (illustrative).
| Item | Value |
|---|---|
| Pallet height (illustrative) | 1,800 mm |
| Film width (illustrative) | 500 mm |
| Overlap (illustrative) | 40% |
| Climb per turn, 500 × 0.6 | 300 mm |
| Turns up the load, 1,800 ÷ 300 | 6 (one climb; top and bottom wraps added) |
What we set per pallet
| Setting | Depends on |
|---|---|
| Top sheet size | Pallet footprint |
| Arm speed | Pallets per hour |
| Wrap program | Load height and stability |
| Film tension | Sack type |
Selection checklist
- Pallet size and height.
- Sack type and weight.
- Pallets per hour.
- Top sheet needed or not.
- Film width.
- Conveyor layout.
Safety
- Stay outside the fence while the arm turns.
- Do not enter the cell while the line runs.
- Lock out before clearing a jam.
- For CE markets, the machine is designed to ISO 12100 and EN 415-6.
Engineering FAQ
Q: Why use a rotary arm wrapper for sacks? A: The pallet stays still while the arm turns, so loose or tall loads are not spun.
Q: What does the top sheet do? A: It covers the top of the load against rain and dust.
Q: How many turns up a pallet? A: 6 turns for a 1,800 mm pallet at 40% overlap with 500 mm film in the worked example.
Q: Can it run in a conveyor line? A: Yes, pallets enter and leave on rollers.
Q: Is the cell guarded? A: Yes, it is fenced with warning signs, as in the clip.
Q: Which standards apply? A: For CE markets, ISO 12100 and EN 415-6.
