Abstract:
A packaging machine of the end-loading type in which sleeve type cartons are loaded in a direction which is transverse to their feed direction through the machine, said cartons having leading and trailing side flaps to be closed after the carton is loaded as the carton feeds through the packaging machine at a carton feed speed, the machine comprising side flap closing means which transversely linearly enter the carton feed path to close said side flaps, said side flap closing means including leading closure lugs having control means controlling drive means to move the leading closure lugs longitudinally linearly in said carton feed direction at a speed less than the carton feed speed and simultaneously transversely linearly so as to engage and close the leading side flaps and thereafter to move the trailing closure lugs longitudinally linearly in said carton feed direction at a speed greater than the carton feed speed and simultaneously transversely linearly so as to engage and close the trailing side flaps.
