ABSTRACT:
A carton activating mechanism (26) for opening the gatefold seats of a paperboard carton blank (13) is disclosed. A rotatable disc (30) carries a spaced series of activators (34), each of which includes a plate (35) having a pair of pivotally-connected fingers (37). The plate is reciprocably mounted on the disc by a pin (36) received in a groove (32) defined on a stationary plate (31) positioned with respect to the disc. Each of the fingers has a projection (40) and a cooperating abutment (41 ) so that the respective fingers are moved outwardly into an extended position, and then spread apart into an open position to fold the gatefold seats of the carton blank before closing and being retracted from the gatefold seats of the carton blank.
