Independent Claim
149 words
A METHOD OF MANUFACTURING CAPACITOR STRIPS FOR REGENERATIVE ELECTRICAL CAPACITORS, WHICH COMPRISE A SELFSUPPORTING INSULATING STRIP WHICH FORM THE OPERATIVE CAPACITOR DIELECTRIC, AT LEAST TWO VARNISH LAYERS, AND AT LEAST ONE METAL LAYER EMBEDDED BETWEEN THE VARNISH LAYERS, COMPRISING THE STEPS OF APPLYING A FIRST VARNISH LAYER UPON AN AUXILLIARY CARRIER FOIL, SUBSEQUENTLY VAPORIZING A METAL COATING UPON SAID LAYER, WITH ANY RESULTING METAL PEAKS THEREBY FORMED EXTENDING INTO SUCH VARNISH LAYER, APPLYING A SECOND VARNISH LAYER UPON SAID METAL COATING, THEREAFTER PLACING THE INSULATING STRIP UPON THE UPPERMOST VARNISH LAYER, PRIOR TO COMPLETE SOLIDIFICATION OF THE LATTER, WHILE THE SAME IS THEREFORE IN A SUFFICIENTLY ADHESIVE CONDITION, PREFERABLY APPLYING PRESSURE TO SAID INSULATING STRIP AND VARNISH LAYER, AND SUBSEQUENTLY REMOVING THE AUXILIARY CARRIER FOIL, WHEREBY A MULTILAYER CAPACITOR STRIP IS FORMED IN WHICH THE SELF-SUPPORTING DIELECTRIC STRIP IS FREE OF ANY METAL PEAKS PRODUCED IN SAID METAL-VAPORIZING STEP.
