Abstract (en)
1. A one-sided corrugated cardboard machine having an upper and a lower corrugated roll for corrugating a corrugation material, especially of paper or cardboard, as well as a pressure roll associated with the lower corrugated roll for connecting the corrugated web to a covering web, with the corrugation of both corrugated rolls being shaped essentially identically and the corrugation peak of the corrugated rolls being formed with a radius which is smaller than the radius of the corrugated ground, characterized in that the flank (13) between the corrugation peak (11) and the corrugation ground (12) is offset backwards vis-à-vis the common tangent of the circular arcs of corrugation peak and corrugation ground and in that the radius of the corrugation ground (12) is greater than that of the corrugation ground (12) essentially only by the thickness of the corrugated material web.
