An improved prefeeder assembly ( ) for receiving a stack ( ) of blanks and for inverting and passing the inverted blanks to processing equipment, the prefeeder assembly ( ) having a rotator frame ( ) which is positonable in an upright load entry position and an inverted bundle discharge position. A rotator infeed conveyor ( ) is supported by the rotator frame ( ) to receive and support a stack while a lift platform assembly ( ) is also supported by the rotator frame ( ) to clamp the stack ( ) onto the rotator conveyor ( ). A backstop and pusher assembly ( ) is also supported on the rotator frame ( ) and includes a moveable backstop ( ) and a pusher member ( ) for discharging a selective height of the stack.

Prefeeder assembly

A load former assembly ( ) for collecting bundles ( ) of materials into tiers ( ) of selected patterns and stacking the tiers ( ), the load former assembly ( ) having a power conveyor ( ) and a dual pin assembly ( ) for horizontal rotation of successive bundles ( ) in a first rotational direction or in an opposing second rotational direction, the dual pin assembly ( ) extending first or second pins ( ) into the path of the bundles ( ). The pins ( ) can be extended at selected lateral positions on the power conveyor ( ). A single pin assembly ( ) having a third pin ( ) is disposed for rotating the bundles ( ) in a set rotational direction. A positioning assembly ( ) positions the rotated bundles ( ) at selected lateral positions on the power conveyor ( ), and the bundles ( ) are collected against a tier gate ( ) to form the tier ( ) in a selected pattern. A sheet dispenser assembly ( ) places slip sheets ( ) onto the tiers ( ).
