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.

A method for producing an edge protector on a clothing for a machine for producing or finishing a fibrous, paper, board or tissue web, the method comprising:

providing the clothing to be provided with the edge protector, the clothing being substantially formed from a woven material with crossing weft threads and warp threads and two side edges lying opposite one another;
applying a film strip to a surface of one of the two side edges of the clothing by heating a surface of the film strip facing the clothing and a surface of the clothing facing the film strip, immediately before bringing the film strip into contact with the clothing, to slightly melt the surface of the film strip and the surface of the clothing;
exerting a pressing force on the film strip applied to the surface of one of the two side edges of the clothing, causing the film strip to penetrate at least partially into the woven material;
and
cooling the side edge of the clothing provided with the film strip, forming a stable connection between the film strip and the side edge of the clothing.
