A blow molding apparatus configured to receive plastic parisons and output blow molded containers including a support frame and a parison conveyor attached to the support frame and having a plurality of parison supports and a drive mechanism for driving the parison supports in a stepped movement circuit, advancing the parison supports by a curvilinear distance corresponding to a curvilinear spacing between a preselected number of parison supports. A first parison transfer assembly is adapted to receive the preselected number of the parisons from the parison supports. A second parison transfer assembly is adapted to receive the preselected number of the parisons from the first parison transfer assembly for transfer to a predetermined number blow mold stations during each stepped movement, and includes the predetermined number of second conveyors having a plurality of second parison supports and adapted for a second stepped movement to advance by a second curvilinear distance corresponding to a second curvilinear spacing between a chosen number of the second parison supports, the chosen number equal to the quotient of the preselected number and the predetermined number. An element for heating the parisons, a parison unloader for disgorging the blow molded containers, and a parison unloader are provided. A method of loading a preselected number of parisons onto a parison conveyor driven in a stepped movement, and transferring the preselected number of parisons to a predetermined number of blow mold stations using first and second parison transfer assemblies.
