Abstract
The present invention is a microwave preheat press. The microwave preheat press includes a first and a second press section which define a press passage therebetween. A compression belt movable along the press passage is contiguous with one of the press sections. The press passage is configured such that it has an initial press section leading into a final press section. A microwave generator is in communication with a microwave waveguide applicator structure assembly such that microwave energy is created and transmitted through the microwave waveguide assembly into the initial compression section.
Claims20
A microwave preheat press comprising:
- a first and a second press section defining therebetween a press passage;
- a compression belt moveable along said press passage contiguous with one of said press sections;
- the press passage having an initial compression section and a final compression section;
- a microwave generator;
- a microwave waveguide applicator structure assembly adjacent the initial compression section, disposed between a fibrous mat and the compression belt, the microwave waveguide applicator structure assembly being configured to direct microwave energy from the generator into the initial compression section;
- and
- a choke configured to inhibit arcing between the microwave waveguide assembly and the compression belt.
