Roll to roll solution with Dynamic Perforation/Punch

The Hunkeler roll to roll solution with different configurations for continuous feed digital presses. High-speed Hunkeler unwinders and rewinders ensure efficient, productive downstream processing in the transactional, direct mail, print-on-demand and packaging segments, coupled with inserters and other finishing systems. The DP8 dynamic perforation module is the first solution that combines perforation in the vertical and cross directions along with punching – all in one unit. “Dynamic” means the ability to change the punching, perforating or hole pattern from sheet to sheet.
