Tool for producing a layer with micro structured outer surface on a substrate surface

摘要

A tool for producing a layer with a micro structured outer surface on a substrate surface is provided. The tool includes an elastic matrix web with a negative of the micro structure to be produced, an elastic pressure roller that is movable over a surface, and at least one guiding element for guiding the elastic matrix web relative to the pressure roller. The pressure roller and the matrix web are arranged in such a manner that when the pressure roller is moved over the substrate surface, the negative on the matrix web faces the substrate surface. In this manner particularly good directional stability and guiding precision of the matrix web can be achieved.

1. A tool for producing a coating layer with a micro structured outer surface on a substrate surface, comprising:
an elastic matrix web with a negative of a micro structure to be produced, an elastic pressure roller that is movable over the substrate surface, a deflection roller, a delivery roller, wherein the delivery roller and the deflection roller together with the elastic pressure roller provide a closed movement path for the elastic matrix web, a frame configured to guide the elastic matrix web relative to the pressure roller, an application device for applying a coating material onto the matrix web, and channel bodies with a drainage channel, wherein the channel bodies extend to edges of the matrix web in at least some regions; wherein the pressure roller and the matrix web are arranged in such a manner that when the pressure roller is moved over the substrate surface the negative on the matrix web faces the substrate surface to thereby produce the coating layer from the coating material with the micro structured outer surface on the substrate surface.
