Each carrier assembly has cam followers which travel within three cam plates, one for controlling an orientation of the carrier assembly, one for supporting the carrier assembly, and one for opening and closing the opening members. The overhead assembly is substantially located on only one side of the articles and cartons and thus provides easy access for repairs, maintenance, or removal of article or cartons jams. The packaging machine can package articles of various sizes and configurations int…
