ABSTRACT:
An article packaging machine (11) for packaging articles such as bottles and cans in cardboard containers comprises a carton path along which cartons are moved to be loaded with articles. The carton path is adjustable in width to provide for use of the packaging machine with cartons of various sizes. A series of automatic retractable bed plate assemblies (26), (27), (28), (29) are provided on the machine for underlying and providing support to cartons moving along the carton path. The bed plates are pneumatically actuated and are adapted to be raised automatically into the carton path as the carton path is widened to provide progressively increasing support. Conversely, the bed plates are lowered automatically out of the carton path as the carton path is narrowed to accommodate the narrowing of the path.
