Abstract

a. Procédé de fabrication de condensateurs à films spiralés sans couches intermédiaires de papier, et condensateurs fabriqués par ce procédé. On forme, en utilisant des films et feuilles lisses, avec deux électrodes et un diélectrique, comprenant au moins un film de matière plastique étiré, en enroulement qu'on imprègne ensuite. b. Afin d'obtenir les interstices microscopiques nécessaires pour l'imprégnation entre les films ou feuilles adjacents, on porte l'enroulement 4 à une température au moins aussi élevée que la température nécessaire pour rétrécir au moins un film étiré 2 adjacent à au moins un autre film 1 qui ne rétrécit pas ou pas autant à la température en question, et on maintient l'enroulement 4 à cette température jusqu'à ce que le film ou la feuille non ou moins rétréci se plisse. c. Permettant de réduire le volume des condensateurs, ce procédé offre de grands avantages pour la miniaturisation, tout en étant réalisable avec l'outillage conventionnel pour la formation des enroulements.
