Abstract: A corrugated pizza box is made using a web fed rotary die cutter with the web produced by a corrugator singlefacer that is speed synchronized with the rotary die cutter. The singlefacer produces SemiCorr Singleface Board (SSB) made possible by special corrugating rolls that allow a bottom liner to be bonded to a fluted and creased medium or liner within the singlefacer. This medium or liner has cross flute bond lines that provide in-line stiffness to the two-ply board exiting the singlefacer.

Abstract: A means of making a multi ply structural panel by eliminating the top liner in the corrugating process. The present invention is made possible through modification to the corrugating rolls of the singlefacer. The design modification to the rolls involves incorporation of slots that run around the circumference of one roll and mating creasing tools incorporated around the circumference of the other of the corrugated roll set. These slots and creasing tools are incorporated across the existing flutes of the corrugating rolls.
