Abstract: A rotary transfer mechanism for transferring flat sleeve cartons (20) from a magazine (22) to a receiving station (23) on a conveyor (24), with opening of the cartons ready to receive end-loaded product, is characterized in that the path of suction cups (32) for holding the cartons during transfer is basically determined by a continuous stationary cam track (34) permanently engaged by a cam follower (37) on a gear segment (35) pivotally mounted on carrier means (29) rotatable by a drive shaft (26), the suction cups (32) being carried by a support shaft (30) rotatable on the carrier means and coaxial with a pinion (38) meshing with the gear segment. (35), and the support shaft being connected to a bracket (48) carrying a manifold (47) for the suction cups (32) by a crank arm (53), which is connected by a link arm (54) to a rocker arm (55) freely rotatable on the drive shaft (26).
