Active Unwinder – Motorized Roll Handling System with Auto Tension & Positioning


Product SKU:


The Active Unwinder is a high-capacity, front-mounted roll feeder designed for COMAGRAV CNC machines that process heavy, roll-fed materials. Engineered to support rolls weighing up to 1000 kg, this industrial-grade unwinder uses a motorized horizontal mechanism and optical sensor array for precise material centering and alignment—minimizing skew and misfeeds during cutting, routing, or laminating operations.

A dancer tensioning system ensures smooth feed rates and automatic tension adjustment, while the quick-lock cylindrical shaft makes roll changes fast and secure. Essential for workflows involving wide-format textiles, foils, or flexible substrates, the unwinder improves operational safety and consistency across long-run or high-volume applications.
