Abstract
Abstract A corona wire tape assembly for a corona charger apparatus, such wire tape assembly providing for a more durable corona wire which is kept substantially clean and which can readily be replaced. The corona wire tape assembly comprises at least one conductive wire adapted to generate ions when having a high voltage from an electrical potential source applied thereto. A flexible dielectric film, separable into lengths substantially corresponding to desired corona wire lengths, encases the conductive wire. The flexible dielectric film defines a first series of openings communicating with the conductive wire to expose the wire to facilitate ion generation and a second series of openings communicating with the conductive wire to facilitate electrical connection of the wire to an electrical potential source.
