Abstract

An apparatus and method for heating parisons or other thermoplastic compots preparatory to forming the component to a different shape, as by blow molding. The parisons are heated by conveying them past an elongated infra-red radiator in spaced relation to the radiator. A concave reflector is provided for each parison, the reflector being movable with the parison in fixed relation thereto. The parison is located at the focal location of the reflector so that heat from the radiator bypassing the parison is reflected back to the parison.
