Abstract: This invention relates to a product cartoning system having dynamic carton carriers that may restrain or not restrain the package during different steps of the cartoning process. Certain steps such as vibrating may benefit from open carton carriers while other steps such as closing a side of the carton may benefit from closed carton carriers. This invention also relates to a product cartoning system having adjustable carton carriers driven by more than one carton chain to allow varying a width between two of the carton carrier sidewalls to accommodate different size or shape cartons. This invention also relates to methods of use for the product cartoning systems of this invention.
