Active Unwinder with Lateral Movement – Precision Roll Feeding for Long-Format Production

ailored for extended-length jobs and heavy roll handling, the Active Unwinder with Lateral Movement mounts to the front of COMAGRAV CNC systems to support rolls up to 1000 kg. Its motorized horizontal feed and optical sensor system provide precise lateral alignment, ensuring clean, centered media presentation even across long-format runs of 20 to 50 meters.

Featuring automatic centering and dancer-controlled tensioning, this module stabilizes roll-fed materials for cutting, creasing, routing, or laminating. The quick-lock cylindrical shaft secures rolls quickly and reliably—reducing operator strain and setup time.
