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 rollers 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.

An apparatus for processing an associated stack of sheet products comprising:
- a drum rotatable about a central axis;
- plural, generally radially disposed pockets defined in said drum having first and second sidewalls defining pocket openings at selected peripheral portions of said drum adapted to receive the sheet products therein;
- plural rollers disposed adjacent the periphery of said drum between said pocket openings adapted to operatively engage one of the sheet products from the associated stack and facilitate entry into a selected pocket;
- means for rotating said rollers around roller axis generally parallel to said central axis during a first preselected portion of said drum rotation;
- and,
- means for preventing rotation of said rollers during a second preselected portion of said drum rotation.
An apparatus for processing sheet products comprising:
- a drum rotatable about a central axis;
- plural, generally radially disposed pockets defined in said drum, each pocket having first and second sidewalls defining openings at selected peripheral portions of said drum for receiving the sheet products therein;
- plural rollers disposed adjacent the periphery of sad drum and interposed between said pockets, said rollers adapted to operatively engage individual sheet products and facilitate entry thereof into a selected one of said pockets;
- and,
- first means for actuating opening and closing movement of said first sidewalls relative to said second sidewalls of each pocket.
