Abstract: An article packaging machine comprises a frame, a carton conveyor mounted to the frame for conveying cartons along a carton path, and an infeed conveyor assembly for grouping articles such as beverage cans into groups of predetermined size and moving them toward and into open cartons moving along the carton path. When the cartons are packed with articles, adhesive is applied to the flaps of their open ends and the flaps are folded over onto themselves. A spring biased free floating compression section has a pair of opposed compression belt assemblies that are yieldably spring biased toward each other to apply pressure to the ends of the containers to set the adhesive, thus sealing the ends of the packaged cartons shut. When the cartons are sealed, they are ejected from the packaging machine by a pair of opposed ejector belt assemblies.
