ABSTRACT:
A case packer for loading open side cases and trays with generally upright articles includes apparatus for controlling the location of the case flaps during the loading operation. A pair of doors is interposed in the path of the articles being loaded. The articles contact the doors, which swing open to push the side flaps out of the way. A plow-like strip is employed to control the location of the case bottom flap. The case blanks are stored in generally vertical stacks in an open-bottom hopper. The blanks are folded and supported so that pulling the lowest blank downwardly partially unfolds the blank before it is deposited onto a conveyor. The conveyor completes the unfolding process while transporting the case to the article loading station.
