Abstract:
A process for treating a surface of a running substrate by an electrical discharge created between two roller electrodes, comprising a first roller electrode and a second roller electrode, in a gas mixture comprising the steps of:passing said substrate in between said two roller electrodes by applying said substrate against the first roller electrode;injecting the gas mixture between the roller electrodes to apply a first surface treatment to the substrate by the electrical discharge between the two electrode rollers, wherein the surface to be treated is exposed to said gas mixture injection;passing said substrate in between said two roller electrodes by applying said substrate against the second roller electrode;injecting the gas mixture between the roller electrodes to apply a second surface treatment to the substrate by the electrical discharge between the two roller electrodes, wherein the surface to be treated is exposed to said gas mixture injection.
