ABSTRACT:
A metallized film suitable for providing a self-preservative metallized film capacitor is prepared. A metallized stock film strip is provided which includes a dielectric film strip and a plurality of deposited metal segments formed thereon so that the deposited metal segments are generally separated from each other but with an electrical connection extending therebetween. The electrical connection is then removed by a short circuit energy or a subsequent slitting. As a result, a metallized film having metal segments deposited on a dielectric film strip can be produced efficiently while avoiding winding wrinkles and a lowering of the process speed.
