DEVICE FOR MANUFACTURING OF FILM ELECTRET Russian patent published in 1995 - IPC

Abstract SU 1774768 A1

FIELD: radio engineering. SUBSTANCE: revolving cassette is positioned at angle with respect to horizontal level. Angle should provide load and unload of dielectric films by means of their weight. Polarization electrode is connected to high-voltage source of alternating voltage. Permanent magnet is located under electrode. Magnet provides tight contact between surface of cassette and metal ring to which dielectric film is glued. EFFECT: facilitated manufacturing. 2 dwg
