APPARATUS FOR MAKING CAPACITORS ABSTRACT OF THE DISCLOSURE Disclosed is an apparatus for making capacitive structures which comprises a plurality of supply spindles, a plurality of sets of support rollers with each set of support rollers being associated with a supply spindle, and at least one rotatable drum. Each of the supply spindles is appropriately proportioned and positioned with respect to the at least one drum to accommodate rotatable mounting of a supply roll of web material in a position and manner where- by each of the respective associated sets of support rollers supports and guides its respective web from the respective supply roll to the at least one drum. The web material has a dielectric substrate with a metallic film upon one side of the substrate. The apparatus further comprises a device for slitting the webs into ribbons prior to winding the ribbons upon the at least one drum to provide alternate layers of metallic and dielectric material. The respective sets of support rollers are each positioned with respect to the at least one drum and the device for slitting webs, to support the ribbons over substantially their full length prior to winding upon the at least one drum. All of the supply spindles, the sets of support rollers, the device for slitting webs, and the at least one drum are aligned so that the ribbons are wound upon the at least one drum to form a plurality of adjacent interleaved rings of capacitive structure.
