Customer-specific adaptation of a pope roller by retrofitting a sensor-controlled pressure roller to avoid air inclusions between the different winding layers.
For surface-sensitive papers (e.g., carbon paper), the nipping force is controlled by the Poperoller. Because the drum movement is controlled in such a way that the roll increase is always compensated, there is a risk that only minimal or no pressure will be applied against the support drum. This can promote the formation of air inclusions between the different paper layers.
