Abstract: A method of forming electrical structures embodying the following steps:(a) providing a carrier sheet having electrodes formed thereon in spaced relation along a length dimension of the sheet, and(b) spirally rolling said sheet about a roll-up axis to bring the electrodes into radial registration, the rolling including transmitting roll-up force to the carrier sheet from a web being translated endwise, adjacent the carrier.
Abstract: A roll-up capacitor structure is embodied by(a) a carrier sheet, and(b) electrodes on said sheet in spaced relation along a length dimension of said sheet, the electrodes having progressively increasing length along said sheet length dimension.
