PET Strap Semi Auto Winder for 9–32 mm Widths
The CQ800 semi-automatic PET strap winder is designed for strap widths of 9-32 mm, covering applications from light-duty hand strapping to heavy-duty petrochemical strapping. It can wind directly from the extruder in parallel and is available with one or two mandrels. The operator manually changes bobbins, while winding, tension control, layering, measurement and stop are fully automatic - balancing efficiency and cost. The central touchscreen stores multiple winding recipes for quick changeover between different PET strap widths and thicknesses, ideal for small-batch, high-mix packaging material factories.

- Wide width range - 9-32 mm, covering most PET strap specifications.
- Semi-auto efficiency - Manual bobbin change, automatic winding - low labor cost.
- High winding accuracy - Can process even waxed PET straps, ensuring neat packages.
- Flexible production - Recipe management via touchscreen, quick spec changeover.
- Powerful drive - Dual servo motors + dancer constant tension.
- Large coil capability - Max 820 mm OD, reduces downstream change-over frequency.
- Proven reliability - Designed for continuous operation with industrial-grade components.
Yes. The machine runs stably at 9 mm and 32 mm; ranges outside can be customized.
Semi-auto means manual bobbin change (mount empty core, remove finished coil), while winding is fully automatic. Fully automatic also does change-over. The CQ800 semi-auto offers better cost-effectiveness.
Yes. The machine features highest winding accuracy, with optional flanges to further prevent slipping.
No. Just modify the recipe parameters on the touchscreen; the layering system adapts automatically.
Yes. Change the value on the touchscreen - the machine accelerates/decelerates smoothly without affecting package quality.
