Product Description
Max 820 mm Package OD PET Strap Winder
Product Overview

The CQ800 semi-automatic PET strap winder produces finished packages with a maximum outer diameter of 820 mm, coupled with a large 406 mm mandrel (or customized). The extra-large coil significantly reduces change-over frequency for end users, making it ideal for high-volume automatic strapping lines or applications requiring long continuous PET strap lengths (e.g., petrochemical, construction). Despite the large diameter, the dancer constant tension system with dual servo motors ensures uniform density and flat end faces from core to outer layer. Semi-automatic unloading uses an assisted arm or manual operation, while winding is fully automatic - balancing large coil capacity and ease of use.

Key Features
  • 820 mm super-large OD - Holds 2-2.5* the length of a typical 500 mm coil
  • Fewer downstream change-overs - Automatic strapping lines run longer, improving efficiency
  • 406 mm large core - Standard for heavy-duty PET straps; customizable
  • Uniform tension inner to outer - Dancer + dual servo ensures large coil quality
  • Precision layering - Electronic 2/3-point or spiral, flat end faces no collapse
  • Semi-auto unloading - Hydraulic assist optional, reduces labor intensity
  • Wide application - Petrochemical, construction, metal strapping, etc.
Frequently Asked Questions
How much more strap length does an 820 mm OD coil hold compared to 500 mm?
With a 406 mm core, the cross-sectional area is about 2.5 times, so length is roughly 2-2.5 times longer. Example: a 500 mm coil might hold 500 meters, an 820 mm coil can hold 1200-1500 meters.
How is such a large coil removed?
Standard configuration uses a manual assisted unloading arm; a hydraulic unloading option is available for one-button ejection, reducing physical effort.
Do I need to reduce winding speed for 820 mm coils?
No. The mandrel can run up to 500 r/min, and line speed is maintained at 250 m/min - the system automatically adjusts rotation speed as diameter grows.
Can the mandrel diameter be changed to 300 mm?
Yes, custom diameters are possible, but we need to re-evaluate layering parameters and coil stability. Please consult us.
Which customers benefit most from 820 mm coils?
Factories with automatic strapping lines, high export volumes, or those wanting to reduce manual change-over frequency - especially in large-scale continuous production environments.
