ABSTRACT:
An apparatus and method for heating and transferring parisons during a blow molding operation. Unheated parisons are heated during their travel through a heating oven, the parisons being freely suspended from an overhead conveyor which intermittently advances the heated parisons into alignment with an overhead discharge opening. A transfer arm rotatable about a horizontal axis above the oven is extended through the discharge opening to engage that heated parison aligned with the opening. Retraction of the arm vertically upwardly removes the parison for later transfer toward a blow molding station. Novel parison suspension means and a drive correlating the movement of the transfer arm and the intermittent parison advancement are disclosed.
