ABSTRACT:
This invention relates to a paper interfolding machine of the type having first and second folding rolls mounted adjacent each other for rotation about parallel axes with porous tissue paper carried by each roll. A wedge-shaped protrusion on a first folding roll and a mating recess on a second folding roll is provided. A resilient member filling at least a portion of the mating recess forms an elastic anvil which is deformed by the protrusion received in the recess to crease a sheet of paper received in the nip between the rolls. Vacuum ports on the second folding roll are used to selectively adhere the sheet to the second roll during creasing.
