Roll to fold solution with WM8

Roll to fold solution with WM8

The paper web provided by the unwinding unit is pulled in by the web merger WM8 and cut longitudinally. The edges can be trimmed simultaneously. After that, the two web halves are placed on top of one another in the merger and fed to the cross cutter. During the merging process, the right web half can be placed below or above the left web half. Optionally, the web can pass through the web merger without being merged.
