ABSTRACT:
A method and apparatus for heating selected portions of an article include transport means for moving the article into a heating compartment. Shroud means, which are disposed within the heating compartment and located adjacent to limited portion of the article, direct a stream of heated gas toward a marginal portion of this article. Supply means deliver a volume rate flow of heated gas to the shroud means, and discharge means remove a volume rate of exhaust gas flow from the heating compartment. The discharge means is constructed and arranged to provide a volume rate of exhaust gas flow from the heating compartment which is greater than the volume rate of heated gas flow supplied into the shroud means.
