METALLIZED FILM CAPACITORS Abstract of the Disclosure The present invention provides a product which has all of the many advantages of pleated, wound, electrical capacitors and also has the added advantage that it may be manufactured with commercially available metallized die- lectric materials. A further advantage of the present invention is that the same basic starting materials may be used to manufacture capacitors that have a number of different pleating combinations. Thus, the invention provides for an electrical capacitor segment which comprises a dielectric layer having a center line, a first metallized electrode layer applied to one side of the dielectric layer so that an unmetallized margin ex- tends along each edge of a pair of parallel edges of the di- electric layer, and a second metallized electrode layer applied to the other side of the dielectric layer so that an unmetallized area is located adjacent the second metallized electrode layer. The dielectric layer is pleated once along the unmetallized areas off of the center line so that one edge of the margin containing edges extends beyond the other of the edges along the same end of the capacitor segment and metallized spray material in contact with the second electrode layer.
