ABSTRACT:
An apparatus to increase the adhesive properties of an electrode material embedded in a synthetic resin matrix of a conductive layer and also to improve the mechanical strength of the composite body comprising the synthetic resin matrix and the embedded electrode material, without giving rise to technical problems in the processing of the composite body into a roll electrode by a known winding process, is provided. Electrically conductive fibers are embedded in the electrically conductive layer and the roll electrode is formed of at least one electrically conductive layer of fiber-reinforced synthetic resins and at least one fiber-reinforced insulating layer of synthetic resins.
Roll electrodes of this type are used as counter-electrodes in corona devices for treating the surfaces of film webs by means of an electrical corona discharge, in order to improve the printability of the film webs or to increase the bond strength of the film webs with other layer materials.
