Abstract
An apparatus and method of using the apparatus for electrostatically depositing powder on moving objects. The apparatus includes powder-spraying chamber, air-filtering units adjacent the entrance and exit of the chamber, and at least one re-ionization chamber disposed between an air-filtering unit and the powder-spraying chamber. Each re-ionization chamber has walls extending transversely to the direction of motion of the objects through the apparatus to direct powder towards the objects on which powder is to be deposited.
