ABSTRACT:
A method and a machine for loading articles into cases utilize indexed rotary movement of a carousel device having a series of angularly spaced platforms, with a case holding device directly above each platform. Articles are pushed onto one of the platforms at an infeed station, in the configuration they will take when packed, with an open-bottomed case held directly above. Then the platform and empty case are rotated to an offloading station, and the platform is raised up into the bottom of the case by camming action, in response to the rotation. At the offloading station, flap folders push the minor bottom flaps of the carton up into closed position, and the case is pushed off the platform onto a conveyor, which also effects closure of the leading major flap up against the minor flaps. There may be three stations, the cases being drawn from flattened, stored configuration and gripped by the case holding device at a station following the offloading station.
