ABSTRACT:
An improvement for use in machinery for interfolding porous cut sheets is disclosed having two adjacent and counter-rotating folding rolls each having projecting tuckers and recessed grippers arranged alternately on the folding rolls such that a tucker on one roll mates with a gripper on the other. Porous cut sheets are selectively adhered to the folding rolls by vacuum ported to the tuckers and grippers.
