Wood and plastic hot-pressing microwave heater - with cavity resonator effecting output through hole in contact with junction point

摘要

The microwave or other high frequency heating device is for hot press joining of wood or other fibrous materials with hot binding plastic foils, or other non-conductive materials. The hole through which the high-frequency output required for heating the pieces is effected is in direct contact with the point where they are to be joined, and is pref. slit-shaped. There may be pressure rollers to attain a close mechanical contact between the resonators holed surface and the junction point. The resonator may be square, with the microwave tube on top and the hole at the bottom in an interchangeable plate. All the components may be part of a woodworking machine.
