Abstract
A corrugator single facer of the type utilizing a large diameter bonding and corrugating roll and a small diameter corrugating roll is driven without direct drive applied to either corrugating roll. Instead, the pressure belt arrangement which supports the lower corrugating roll to provide the nipping force includes a series of driven supporting pressure belts that are loaded against the lower corrugating roll and which transmit rotational movement thereto and through the nip to the large diameter bonding roll.
