Abstract
An apparatus for making capaticive structures, which apparatus provides a plurality of supplies of webs, each web having a dielectric substrate with a metallic film upon one side of that substrate. The apparatus further provides a rotatable drum spaced from the supplies of webs, a plurality of rollers associated with each web supply with each web being strained and tensioned over its respective plurality of rollers, and a means for slitting the webs into ribbons prior to winding the ribbons on the drum to provide alternate layers of metallic and dielectric materials. The rollers and slitting means are positioned with respect to each other and with respect to the drum to support the ribbons over substantially their full length prior to winding on the drum.
