Roll to stack with DP8 and WM8

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. The paper web is pulled in by the web merger WM8 and cut in the center. The edges can be trimmed simultaneously. Waste produced during the edge trimming is collected by a funnel and removed by means of an external waste exhauster. After that, the two web halves are placed on top of one another in the merger and fed to the cross cutter. The web halves can be merged left under right or right under left.
