1 or 2 Mandrels – Fast Manual Bobbin Swap PET Winder
Product Overview

The CQ800 semi-automatic PET strap winder is available with 1 or 2 mandrels. The two-mandrel version allows the operator to pre-load an empty core on the second mandrel while the first mandrel is winding. When winding is complete, a quick manual swap can be performed - fast manual bobbin change - dramatically reducing idle time. Each mandrel is equipped with a pneumatic mandrel for core mounting/unmounting in seconds. The dual-mandrel design is especially beneficial for frequent change-over scenarios (small coils or multiple specifications), increasing overall productivity in semi-automatic mode by 30-50%. The single-mandrel version suits cost-sensitive users with low change-over frequency.

Frequently Asked Questions
Q1: How much efficiency gain does dual mandrel provide over single?
A: For small coils (e.g., 300 mm OD), change-over is frequent. Dual mandrel can reduce downtime by over 50%, increasing overall output by 30-50%.
Q2: How does change-over work on the dual-mandrel model?
A: When the first mandrel finishes and stops, the operator presses the swap button. The second mandrel moves into winding position, guide the strap end quickly, and start winding. The finished coil on the first mandrel can be removed later.
Q3: Is there much strap waste during change-over?
A: Very little. The machine features a strap end catcher and pre-wrap function, consuming only about 0.5-1 meter per change.
Q4: Can a single-mandrel be upgraded to dual later?
A: Yes. The CQ800's modular design allows field addition of a second mandrel assembly, but manufacturer technical support is required.
Q5: Is the dual-mandrel model more complex to maintain?
A: Barely. Two sets of pneumatic mandrels and drives are simple and robust. There are slightly more lubrication points, but maintenance time is similar.
