PRODUCT HEAT TREATMENT METHOD AND APPARATUS THEREFOR

摘要

An apparatus and method for the heat treatment of a product such as in the curing of rubber-like materials and the thermoforming of plastics materials. A metallic heat transfer member is provided for contacting the product to transmit heat thereto. In order to obtain a uniform temperature distribution over the heat transfer member/product interface, one or more gas distribution passageways receive hot gas from a hot gas source such as a gas burner and lead the hot gas to the heat transfer member. One or more heat transfer passageways contiguous with the heat transfer member communicate with the gas distribution passageway so as to receive hot gas from the latter passageway and lead same to an exhaust outlet.
