Abstract

An apparatus for processing sheet products includes a rotatable drum having a plurality of pockets adapted to receive individual sheet products. Plural rollers are disposed along the periphery of the drum between adjacent pocket openings. The rollers are rotated through a portion of the drum movement and locked against rotation through the remainder of the drum movement. Cam means are provided to lift the pockets radially outward, tilt the pockets, and open and close sidewalls of the pockets to facilitate ingress and egress of the sheet products.
