Abstract
A corrugating roll design for a corrugating machine including a pair of parallel, spaced apart, corrugating rolls which rotate in opposite directions on their respective rotational axes, the rotational axes being spaced apart a predetermined distance, and each of the corrugating rolls being formed along its outer peripheral surface with longitudinally extending teeth with tooth tips and tooth roots. Depressions are provided in the tops of the tooth tips of at least one of the corrugating rolls and spaced apart a predetermined distance along the length of the roll. Each of the depressions has a bottom surface which is located to establish a spacing between the bottom surface of the depression and the tooth root of the other corrugating roll at the actual corrugation impression zone in the nip, which spacing is greater than the thickness of the paper medium.
