Abstract
A method and apparatus are shown for securing a top for a cardboard carton where the carton has a bottom wall and integral sidewalls, an initially open interior and initially open top flaps with outwardly extending ears. The top flaps are folded to a carton closing position which closes off the initially open interior of the cardboard carton. The ears are also folded to a position in contact with the sidewalls of the carton. A set of punches are aligned with the folded ears of the carton and are actuated to force a first layer of cardboard from a respective top flap through an underlying region of the carton sidewall. A set of platens are located so as to underlie and reinforce the sidewalls of the carton as the punching operation takes place.
