  • Patent number: 4263638
    Abstract: A dual wound capacitor is provided in which two capacitors with a common electrode are provided or two separate capacitors are provided in a single winding operation. First and second metallized dielectric films are wound through a predetermined number of turns to a position preceding a gap in at least one of the metallized sides of the film. The gap is formed by removing or omitting metal from an intermediate portion on the dielectric film either before the capacitor is wound or during the winding process. The gap so formed may be as narrow as an eighth of an inch and, under any circumstance, is substantially less than the length of one winding of the capacitor. An insulated sheet having a length sufficient to encircle the gap is inserted and wound between first and second metallized dielectric films and extends outwardly from one side of the capacitor to form an overlapping circular barrier which separates the metallized portions on each side of the gap.
