Abstract
In a method of continuous fabrication of mother-capacitors, a mother-film of substantial width is first metallized and cut so as to form intermediate films. A border is then formed on each intermediate film by means of a YAG-laser beam. Each intermediate film is then cut so as to form individual films by means of a CO.sub.2 -laser beam, the beam spot being located in proximity to the YAG-laser beam spot on the intermediate film. After relative displacement of the individual films, they are wound on a wheel of substantial width so as to form an array of n mother-capacitors. A single intercalary element is placed between two tiers of an assembly of m mother-capacitors, thus endowing the assembly with good stability. The two outer rings of mother-capacitors are finally cut-out after spray-coating.
