ABSTRACT:
A single facer machine of the vacuum or fingerless type for making a corrugated paperboard laminate. A new means for applying vacuum to the paperboard on the second corrugator roll. The second corrugator roll is provided with axially spaced circumferential grooves, the grooves being deeper than the flutes on the roll. Each groove is provided with a vacuum finger, coupled to a source of vacuum, each vacuum finger being curved at its intake mouth which sealingly engages the sides of its respective groove to supply vacuum thereto. The angular extent of the curved intake mouth is supplementary to the angular extent of engagement of the corrugated paperboard with the second corrugator roll.
