ABSTRACT:
A method and apparatus for separating interconnected stacks in a pack of multiple stacks. The pack is confined and an impact wheel is pivoted into the pack at the juncture of the interconnected stacks. The wheel is frusto-conically shaped and the impact of the wheel first breaks the interconnection and then lifts the edge of one of the stacks while a holding shoe on the other stack holds the mated side edge of that juncture. A pivotal spread bar engages individual stacks with the remainder of the pack being confined to complete separation of the interconnection. Conveyor means conveys the stacks towards a packaging machine.
