ABSTRACT:
A system for feeding electromagnetic energy into a cavity for heating material contained therein includes a radiator of the electromagnetic energy and a motorized support for carrying the radiator within the cavity by the material. The radiator is constructed of a material such as alumina providing a much shorter wavelength than that existing in the environment surrounding the material to permit the radiator to have a sufficiently small size to be inserted within the cavity. Heat may also be provided by directly heating the walls of the cavity in which case the radiator is provided with a taper for directing the electromagnetic energy into the thicker portions of the material so that all portions of the material are heated at a uniform rate. The feed system includes a support for a bladder which is useful in urging uncured rubber of a tire casing against the interior surface of the cavity for forming a rubber tire.
