Abstract: A method for producing an edge protector on a clothing for a machine producing or finishing a fibrous, paper, cardboard or tissue web, includes providing a clothing formed substantially from a woven fabric with crossing weft and warp threads and opposite side edges, applying a film strip onto a surface of one side edge and, immediately before bringing the film strip into contact with the clothing, surfaces of the film strip and the clothing facing each other are heated to slightly melt the surfaces. A pressing force exerted on the film strip applied to the surface of one of the side edges, results in the film strip penetrating at least partially into the woven fabric. That side edge of the clothing with the film strip is cooled, resulting in a stable, particularly integrally joined and form-locking connection between the film strip and the side edge of the clothing.
