The invention relates to a method for treating an elongated object using a plasma process. The method comprises the steps of providing an elongated object in a planar electrode structure, and applying potential differences between electrodes of an electrode structure to generate the plasma process. Further, the method comprises at least partially surrounding the elongated object by a unitary section of the guiding structure, the electrode structure being associated with the unitary section.

Method for treating an elongated object, apparatus and method

A plasma source has an outer surface, interrupted by an aperture for delivering an atmospheric plasma from the outer surface. A transport mechanism transports a substrate in parallel with the outer surface, closely to the outer surface, so that gas from the atmospheric plasma may form a gas bearing between the outer surface the and the substrate. A first electrode of the plasma source has a first and second surface extending from an edge of the first electrode that runs along the aperture. The first surface defines the outer surface on a first side of the aperture. The distance between the first and second surface increasing with distance from the edge. A second electrode covered at least partly by a dielectric layer is provided with the dielectric layer facing the second surface of the first electrode, substantially in parallel with the second surface of the first electrode, leaving a plasma initiation space on said first side of the aperture, between the surface of the dielectric layer and the second surface of the first electrode. A gas inlet feeds into the plasma initiation space to provide gas flow from the gas inlet to the aperture through the plasma initiation space. Atmospheric plasma initiated in the plasma initiation space flows to the aperture, from which it leaves to react with the surface of the substrate.

An electrode assembly for use in a dielectric barrier discharge plasma source comprises a base metal plate, an enamel layer on a surface of the base metal plate and embedded electrodes embedded in the enamel layer. The electrode assembly may be made by depositing a one or more layers of powdered glass over a surface of the base metal plate, fusing the powdered glass the one or more layers each in a separate heating step for the relevant layer. To form the embedded electrodes, a pattern of electrode material is provided over the powdered glass of the one or more layers after fusing the one or more layers. Subsequently one or more further layers of powdered glass are deposited over the electrodes and the layer(s) below it, and the powdered glass in each of the one or more further layers is fused in a separate heating step.
