AbstractAn electric discharge corona discharge device is disclosed which is useful for rendering of the surface of plastic molded parts capable of being adhesively bound to another part. The device includes flexible, limp counter electrodes which can be adjusted so as to maintain a substantially uniform discharge over the plastic part surface. The discharge is obtained with alternating current and the base underneath the plastic part constitutes the base electrode.
