A method and apparatus for vulcanizing extruded rubber profiles in vulcanizing ovens to eliminate under cure of the rubber profiles in those areas where the extruded rubber profiles contact a support means by arranging at least one microwave emitter below and in close proximity to the support means. The support means having a high dielectric constant to provide a low reluctance path therethrough so that the microwave energy passes through the support means into the rubber profiles to improve curing of the rubber profiles in the areas where they contact the support means.

Method and apparatus for microwave vulcanization of extruded rubber

A method and apparatus for preventing microwave leakage at a conveyor portal channel of a microwave oven where a product to be treated is moved therethrough on a conveyor means, including the steps of positioning partitions on the conveyor means which carries the materials to be heated through the portal channel, and providing spaced protrusions between the moving peripheral walls of the partitions and the portal channel walls, thereby preventing microwave leakage from the oven.
