Abstract
An apparatus for simultaneous electrical discharge treatment and adhesive application to a polymer component. The apparatus includes a jig having an electrically conductive region and a dispenser having an electrically grounded dispensing tip with a dispenser orifice which functions as an electrode as it is moved across an upper surface of the polymer component in close proximity thereto. During such movement, the tip coacts with the jig which underlies the component and to which high voltage is applied to create an electrical discharge which is directed onto the component and makes the surface thereof susceptible to bonding with adhesive applied to the component from the tip virtually simultaneously with the discharge.
