ABSTRACT:
An overhead pusher lug assembly for stabilizing the top portions of cartons in a carton packaging machine comprises an endless chain conveyor having an array of pusher lugs rotatably mounted thereto at spaced intervals. The lugs are rotatable between a first position wherein the lugs extend upwardly from the lower flight of the conveyor and a second position wherein the lugs extend downwardly from the lower flight of the conveyor for insertion between adjacent cartons on a carton conveyor. As the pusher lugs move onto the lower flight of the conveyor, they engage the end of an elongated bar, which rotates or flips the pusher lugs into place between underlying cartons so that the lugs do not impact and disfigure trailing cartons on the carton path.
