Abstract

A capacitor comprises a plurality of layers 18a, 18b each layer comprising a dielectric substrate 6a and a metallic film 8a extending from one edge to the other but including a zone 10 free of said metallic film and adjacent to but spaced from one edge to leave a narrow marginal metal film band 24 at said edge. The layers are disposed alternately offset and reversed laterally, such that alternate edges 33 of layers 18a lie beyond the marginal band edged 36 of the layers 18b, and vice versa at the opposite side of the capacitor. The outwardly lying edges 33, of the layers are coated with electrically- conductive material 40a to connect electrically the alternate metal film layers in two groups. The capacitors are made by laser- scribing parallel metal-free zones onto webs A and B. The webs are slit into ribbons by blades 21a prior to winding onto a drum 20 on offset and laterally reversed fashion, to produce a plurality of side-by-side annular layered members. Rollers 16a, 16b and said slitting blades 21a are close to the drum 20, such that the slit ribbons are supported over substantially their full lengths prior to winding onto said drum. The annular members are separated and individually cut transversely to the ribbons, to form stacked capacitors.
