Abstract
Process for the manufacture of an electric capacitor, which is wound from a sheet of dielectric and sheet metal layers located between it and then subjected to a heat treatment, in which the dielectric sheets composed of artificial material susceptible to be deprived of their stretching, especially of stretched polystyrol, was at least partially deprived of its stretching, characterized in that at the beginning of the roll vacuum wrappings of the dielectric sheets are applied, which by the heat treatment contract, especially they are joined by heat, to constitute a solid core of artificial material, especially a polystyrene core.
