A tape-on drywall accessory includes an elongated metal core strip with a longitudinal arcuate nose and a pair of flanges extending outwardly from the nose. A cover strip of paper is bonded to the exterior surface of the core strip, and includes wings that project outwardly beyond the extent of the flanges. The cover strip is formed of a non-latex-bearing stock paper having high pick resistance and which is dimensionally stable and has high peel bond strength when in contact with wet joint compound.

Paper bead

A corner bead is of the tape-on type, having an elongated metal core strip with a longitudinal arcuate nose and a pair of flanges extending outwardly from the nose at approximately a right angle. A cover strip of paper is bonded to the exterior surface of the core strip, and includes wings which project outwardly beyond the extent of the flanges. The cover strip is formed of a stock paper having high abrasion resistance, tensile strength, and which is dimensionally stable on contact with wet joint compound.

Paper bead and trim

A corner bead is of the tape-on type, having an elongated metal core strip with a longitudinal arcuate nose and a pair of flanges extending outwardly from the nose at approximately a right angle. A cover strip of paper is bonded to the exterior surface of the core strip, and includes wings which project outwardly beyond the extent of the flanges. The cover strip is formed of a stock paper having high abrasion resistance, tensile strength, and which is dimensionally stable on contact with wet joint compound. The surface of the cover strip is abraded to partially loosen the surface fibers, which will increase the bond strength of the comer bead when installed on wallboard. The method of manufacturing a tape-on corner bead includes the steps of conditioning a strip of stock paper by abrading the surfaces of the paper, and then bonding the paper strip to an outward face of an elongated core.
