An apparatus for heating selected portions of an article (4) includes transport means (2) for moving the article (4) into a heating compartment (6). Shroud means (8), which are disposed within the heating compartment (6) and located adjacent to limited portion of the article (4), direct a stream of heated gas toward a marginal portion of this article (4). Supply means (10, 12) deliver a volume rate flow of heated gas to the shroud means (8), and discharge means (14, 16) remove a volume rate of exhaust gas flow from the heating compartment (6). The discharge means (14, 16) is constructed and arranged to provide a volume rate of exhaust gas flow from the heating compartment (6) which is greater than the volume rate of heated gas flow supplied into the shroud means (8). A corresponding method is disclosed as well. |
