Abstract

The apparatus for the indirect corona treatment of conducting and nonconducting materials, for example sheets of plastic, paper, metal and/or fabric or mouldings made of these materials, is used to increase the surface energy with the aid of two electrodes situated on the same side of the material to be pretreated, which moves with respect to them. Pressurised gas is fed to the discharge gap between the electrodes in order to deflect the discharge arc in a suitable manner. The appropriate electrical voltage is generated by a transformer (1). The two electrodes take the form of bare metal electrodes (12) and they form a pair of pin electrodes. There is no dielectric on either of the two electrodes. If both electrodes are live, a capacitor (13, 14) is inserted between the two electrodes and the transformer. If only one electrode (12) is live, a suitable capacitor (13) is provided for this electrode alone, while the other electrode is at earth. The purpose of the dielectric in conventional apparatuses is virtually assumed by the condenser or condensers. The gas stream provided for each electrode pair provides the appropriate deflection of the spark channel in the direction of the surface to be treated. This results in a simple and compact treatment unit which can be used universally and achieves a very good treatment result with a very simple construction (Fig. 3A). <IMAGE>
