Abstract
A resonant high-frequency or micro-wave applicator for the thermal treatment of a flat material is disclosed. This applicator comprises a flat capacitor between the plates of which the material moves and an inductor which is constituted by a metal band extending transversely the plate acting as hot electrode. The inner face of the plate acting as ground electrode is divided into elementary sections by an assembly of longitudinal grooves. Preferably, the same applies to the inner faces of the plate acting as hot electrode and the inductor.
Claims9
A resonant high-frequency of micro-wave applicator for the treatment of a flat material, comprising a flat capacitor including at least two plates between which said material moves and an inductor, constituting with the capacitor an oscillating circuit, the inductor being constituted by a metal band transversely extending the plate of the capacitor acting as hot electrode, and the plate of the capacitor acting as ground electrode having its inner face divided into elementary sections by an assembly of longitudinal grooves in a direction of displacement of the material.
