Abstract
A paperboard blank stacker assembly for supplying a stack of paperboard blanks to a container forming machine includes a stacker. The stacker has multiple blank stops arranged to hold a peripheral edge of a bottom blank of the stack of paperboard blanks, with the multiple blank stops defining an interior region. A blank carrier has at least one suction device moveable into a grasp position, where the suction device applies a suction force to the bottom blank, and a removal position, where the suction device is moved to remove the bottom blank from the stack of paperboard blanks by pulling the bottom blank through the interior region.
