Abstract
A carton flap folding assembly (10) and a method of folding carton flaps is disclosed. The carton flap folding assembly includes a rotatable cam plate (25) which defines upper and lower cam tracks (29, 30). The cam plate is affixed to drive sprockets (35, 36) which drive associated chains through a lower chain guide (45) or an upper chain guide (50), respectively. Lever assemblies (62, 70) operatively engage the cam track, and effect shifting of an associated chain guide. A plurality of lugs (87, 88) project from the upper and lower chain, and are arranged to comprise composite lug assemblies (91). The composite lug assemblies are moved into prescored flap areas of a carton blank, and fold the flaps inwardly to a first extent. The lever assemblies are actuated to slide the chain guides in opposite directions, which moves the lugs mounted to the upper and lower chains in opposite directions. This movement folds the flaps to a second extent. The separate lugs are then returned to their composite arrangements and withdrawn from the carton blank.
