500mm Infinitely Adjustable Traverse PET Winder

PET Strap Semi-auto Winder Max 500kg/Coil Extra-Large 1250 mm OD 500 mm Traverse
Production Overview
The CQ1200-1 fully automatic PET strap winder produces extra-large finished packages with a maximum outer diameter of 1250 mm and a maximum traverse length of 500 mm, meeting heavy-duty packaging and long-length requirements. The extra-large coil dramatically reduces change-over frequency for end users, making it ideal for large-scale automatic strapping lines, petrochemical, or construction industries. The traverse length is infinitely adjustable from 50-500 mm via the touchscreen, with no mechanical part replacement needed. The machine handles PET straps of 9-32 mm width, winding speed 50-250 m/min, and dancer constant tension with dual servo motors ensures uniform density from core to outer layer. An optional dual-mandrel configuration enables fast manual bobbin change. Central recipe management stores multiple processes for quick spec switching.

Key Features
  • 1250 mm super-large OD - Holds 2-3* the length of a typical 800 mm coil.
  • 500 mm extra-wide traverse - Produces very wide coils for large automatic strapping machines.
  • Fewer downstream change-overs - Greatly reduces user change-over frequency, improving packaging line efficiency.
  • Wide traverse infinitely adjustable - 50-500 mm continuous, set on touchscreen.
  • 406 mm large core - Standard for heavy-duty PET straps; customizable.
  • Constant tension + dual servo - Uniform density even for extra-large coils.
  • Recipe management - Quick changeover between different widths and thicknesses.
Frequently Asked Questions
Q1: How much more strap length does a 1250 mm OD coil hold compared to a typical 800 mm coil?
A: With a 406 mm core, the cross-sectional area of a 1250 mm OD coil is about 2.5 times that of an 800 mm OD coil, so length is roughly 2.5 times longer. For example, an 800 mm coil might hold 800 meters, a 1250 mm coil can hold over 2000 meters.
Q2: What is the practical use of a 500 mm traverse length?
A: For producing extremely wide PET coils, such as those needed for large automatic strapping machines requiring 400-500 mm width, or special export orders. For narrow straps, the traverse can be reduced.
Q3: Does layering precision decrease at 500 mm traverse?
A: No. The electronic layering system automatically optimizes the layering curve for the set length. The servo-driven ballscrew provides high positioning accuracy, ensuring neat end faces.
Q4: How is such a large coil removed from the machine?
A: The machine is available in semi-auto or fully auto configurations. Semi-auto uses an assisted unloading arm; the fully automatic version uses an integrated conveyor system. Hydraulic assist is optional.
