Abstract
The present invention is a method and apparatus for non-contact cleaning of a web. The method and apparatus involves producing alternating electrostatic forces to separate particles from the surface of the web. The apparatus utilizes an electrode to produce a corona discharge in a gap formed between the electrode and the surface of the moving web being treated. An air supply arrangement is provided to supply air to and remove air from the gap to remove the particles which have been lifted from the surface of the web due to the corona discharge.
