ABSTRACT:
Method and apparatus for electrostatically charging a web or film by subjecting the web or film to an electric field generated between a single bar or wire electrode and the curved surface of a second electrode, and optionally sequentially subjecting the web or film to subsequent electric fields preferably in which the polarity of the field, relative to the web or film, is reversed.
