Abstract

Dans ce procédé on utilise pour former le bobinage deux demi-broches cylindriques et on serre entre elles des extrémités de films métallisés, par exemple deux, et une extrémité d'une feuille thermoplastique dont la largeur dépasse celle des films et dont la longueur est suffisante pour obtenir après réalisation du bobinage et après retrait des demi-broches un tube axial 18 dans le conduit du bobinage qui dépasse par ses deux extrémités le bord des tranches. Par ramollissement ou fusion à l'état pateux de ces deux extrémités les deux orifices du tube sont ensuite obturés. Application : condensateurs à films diélectriques métallisés.
