Direct Parallel Winding PET Strap Auto Winder with Dancer Constant Tension and 820 mm Max Package OD

The CQA800F fully automatic PET strap winder supports direct parallel winding from the extruder, eliminating the need for accumulator stands. After cooling, the strap enters the winding station directly from the extruder exit, while the dancer constant tension system automatically compensates for minor speed fluctuations between extrusion and winding, ensuring smooth operation.

This design effectively shortens the total production line length, reduces strap exposure time, and lowers contamination and stretching risks. The machine can be integrated into a fully automated plant or run independently. After winding completes, it automatically wraps the package with film, flips it down to the roller conveyor below, and simultaneously feeds a new tube from the magazine - achieving continuous production.

• Direct connection - Eliminates accumulator and buffer rollers, simplifies line.
• Speed adaptive - Dancer constant tension automatically compensates extrusion/winding speed differences.
• Shortens line length - Reduces equipment footprint, lowers building cost.
• Reduces contamination - Short exposed strap path lowers dust and oil pick‑up.
• Prevents stretching - Fewer rollers reduce accidental strap deformation.
• Easy installation - Place after extruder cooling section; no line modification needed.
• Automation ready - Can communicate with extruder PLC for coordinated control.
