ABSTRACT:
The process of the present invention is for the surface treatment on both sides of a substrate by means of electric corona discharge, while simultaneously treating both surfaces of the substrate with a carrier gas/aerosol mixture introduced into the corona discharge zone. The arrangement for carrying out this process comprises a corona discharge device, consisting of a generator, high voltage electrodes, to which alternating current is applied by the generator, as well as grounded counter electrodes, a device for the atomization of liquid into a suspendable aerosol, which is connected via a transport line for the aerosol to the corona discharge device, and a blower, which is connected to the atomizer device and conveys the carrier gas/aerosol mixture to the corona discharge device. The electrodes and counter electrodes together form a gap for the substrate to be treated.
