ABSTRACT OF THE DISCLOSURE LIMP BAG STACK PLUNGE LOADER WITH INSERT STABILISING MEANS A novel method and apparatus is disclosed for the loading of a carton with a full complement of plastic bags and a cardboard insert. A plunger descends and contacts an insert which, in turn, forces a stack of plastic bags into an empty carton disposed directly below. The plunger has the additional capability of creating an internal vacuum which fastens the insert to the plunger, and the plunger is then used to contact the stack of flexible articles such as plastic bags and force the same into the carton. The vacuum within the plunger is subsequently collapsed while the plunger is within the carton thereby releasing the insert while it is within the carton, and additionally facilitates withdrawal of the plunger therefrom. A pair of intermeshing rollers are also provided to further guide the bags into the carton. Both gusseted and non-gusseted bags can easily be loaded pursuant to the teachings of the present invention.
