Abstract
Abstract Method and apparatus for heating a body, especially a long continuous body such as rubber belting, by microwave heating in an enclosure which is moved relative to the body being heated. In the examples described this is done by a reciprocating device, the belting being held stationary during heating. The support structure on which the enclosure is movably mounted is preferably pivoted at one end on a fixed axis and pivoted at the other end to the moving platen of a vulcanization press.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
117 words
Apparatus for heating an elongate body by microwave energy, including a microwave enclosure having means for admitting microwave energy to the body, support means for holding the body stationary independently of the enclosure, and a reciprocating device for subjecting the enclosure to a reciprocating motion in a direction parallel to the plane of the body, said enclosure having an inlet opening at one end for admission of the body and an exit opening at the other end, a choke being provided at each of said inlet and exit openings for reducing escape of microwave energy from the enclosure, and said support means including a conveyor belt mounted independently of the enclosure but passing therethrough through said openings.
