Roll to stack with WF8
The paper web provided by the Unwinder UW8 is pulled in by the Web Folder WF8 and perforated or creased longitudinally. The edges can be trimmed simultaneously. Paper waste produced during the processing is collected by a funnel and removed by means of an external waste exhauster. After that, the web is plow-folded in the folder and transferred to the Cross Cutter.
