Method and apparatus for microwave vulcanization of extruded rubber profiles

摘要

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.
