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.
