continuous operation for the windings of the cover layers so that continuous metal free strips are formed application_number US 1313587 A description a laminated stack type capacitor is shown in fig1 partially exploded to reveal the first four and the last one of dielectric layers 4 and 5 which form a consolidated stack 1 the dielectric layers 4 and 5 include metallic coatings 2 and 3 which are applied thereto as thin metal layers of valve metal the valve metal is preferably aluminum or zinc and extends up to two long sides 27 and 28 of the consolidated stack 1 the coatings 2 and 3 can also extend up to the upper narrow side or top 29 however in the embodiment shown the coatings 2 and 3 are spaced from the top 29 by metal free strips 30 and 31 first and second projections 8 and 9 are formed in a narrow side or bottom of the stack 1 opposite the top 29 the projection 8 and 9 having respective ends 6 and 7 the metal coatings 2 on the dielectric layers 4 extend up to the ends 7 of the projections 9 whereas the coatings 3 on the dielectric layers 5 extends up to the ends 6 of the projections 8 on alternating ones of the dielectric layers 4 and 5 metal free insulating strips 15 and 16 respectively are arranged on the respective projections 8 and.
