Abstract
A cam assembly (10) for a carton blank feeder mechanism comprises a cam plate (16) having formed therein a first continuous cam track (44) and a second relatively shallower cam track (46). A cam track follower arm (26) includes a first follower (30,32) for relative movement within only the first continuous cam track and a second follower (28) for relative movement within the first and second cam tracks. Drive means (12,24) are provided for moving the follower arm relative to the cam plate and article pickup means is connected to the cam arm by an eccentric arm (34). The first and second cam tracks includes arcuate portions (44c, 46d) engaged sequentially by respective ones of the first and second followers so that the article pickup means is caused to move to an outwardly extended position and to an inwardly retracted position, respectively, relative to a central axis of the cam plate.
