The web de-dusting module PEM removes the dust from the paper webs. The PEM has two de-dusting heads for cleaning both sides of the paper web in continuous operation.
Roll to stack solution with Web Merger WM8
Roll to stack with WM8
The paper web provided by the Unwinder UW8 or the printer via the Web Buffer WB8 (for inline applications) 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 Web Merger and fed to the Cross Cutter. The web halves can be merged left under right or right under left.
