A transporter apparatus for movement of plastic blister members to a conveyor for processing, i.e., for receiving an article in a pocket of the same and a backing card for closing the pocket opening and enclosing the article therein, includes a frame for supporting an assembly having a carriage movable in the vertical direction and a plurality of transfer rods supported by the carriage. The transfer rods are disposed in a horizontal attitude and divergent outwardly from a pick-up zone of blister members to the conveyor. Transfer devices including structure for "gripping" the blister members are supported by the transfer rods. The transfer devices are connected to a pair of transfer arms and driven along the transfer rods as the transfer arms are themselves driven. A drive mechanism including mechanical actuators impart movement to both the carriage and the transfer devices upon control signals to the drive mechanism.
