ABSTRACT:
A hopper apparatus for folding the end flaps of a film overwrapper across the ends of a carton enclosed in the overwrapper includes a back wall, two parallel side walls, and an access door closing the front side of the hopper. The top horizontal edges of the side walls, back wall, and closed access door define the open top end of the hopper, and the horizontal bottom edges of the back wall, side walls and closed access door define the open bottom end of the hopper. Carton engaging fingers are attached to the back wall for movement into and out of the hopper, and carton engaging fingers are also attached to the access door at the same elevation in the hopper as the engagement fingers on the back wall for movement into and out of the hopper.
