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.

Abstract: A flexible, heat-controlled doctor knife has a flat, flexible, heat-generating element affixed to one side of the knife blade. Blade flexing means which can adjust the angle of the working edge of the knife are provided on one side of the blade, adjacent to the working edge. The heat-generating element provides uniform heating of the knife and is a laminate having an electrically-conducting layer with alternating layers of a synthetic resin insulator and aluminum foil. An edge of the heat-generating element extends adjacent to the blade flexing means. Temperature control means regulate the heating of the blade.
