Method for increasing the adhesion between the first surface of a first web-shaped material and a first surface of a second web-shaped material

Abstract

A method for increasing the adhesion between the self-adhesive surface of a web-shaped material and a surface of a substrate, to which substrate the web-shaped material having the self-adhesive surface should be applied, wherein the web-shaped material is continuously fed to a laminating gap, in which the web-shaped material having the self-adhesive surface is laminated onto the surface of the substrate, the self-adhesive surface of the web-shaped material and the surface of the substrate are treated with a plasma over the entire area, and namely in such a way that the plasma is applied continuously to the two surfaces, starting from before the laminating gap into the laminating gap, the laminating gap being formed by a pressing element and the substrate and the surface of the pressing element being equipped with a dielectric.
