symmetric profile of the finished corrugated paperboard results.
In the region of contact between the second fluted roller and the pressure contact roller, contact between the profile peaks of the second fluted roller and the essentially cylindrical surface of the pressure contact roller takes place. As a result of this, the axial distance between these two rollers, defined by the contact between the second fluted roller and the pressure contact roller, varies continually in the course of rotation of the rollers between a maximum value, when a profile peak is located in the region of a plane containing the centerlines of the rollers, and a minimum distance, when a profile valley of the second fluted roller is located in the connecting plane containing the centerlines of the rollers.
