摘要： An elongated grid runner, and its manufacture, comprising a pair of overlying metal strips roll-formed together into a shape suitable for use in a rectangular grid to support ceiling panels, one of said strips serving as a visible cap for concealing the other strip forming the main body of the grid runner when the grid member is employed in a completed ceiling, the strips being lanced at each end of the grid runner to lock the cap strip on the main body strip whereby when the overlying strips are simultaneously cut to a finish length prior to finish roll-forming, the ends of the strip are maintained in substantially overlying end-to-end registration where the cap is visible in a finished ceiling.

摘要： A drywall corner bead providing a rounded nose and two mounting flanges extending from opposite sides of the nose is formed from a strip of galvanized metal of uniform thickness. The two flanges are provided with three discrete longitudinally extending bands of reduced thickness formed by shear deformation of the material forming the band. The flanges are knurled to emboss the surface thereof and openings are formed in the flanges at intervals along their length. The corner bead is formed by a method in which shear deforming forces are progressively applied to the material forming the thinned bands to produce lateral deformation of such material without any appreciable lengthwise deformation. After the thinned bands are formed, forces are applied to straighten the corner bead. Subsequently, the flanges are knurled to provide an embossed surface and holes are punched in the flanges at intervals along their length. Thereafter, the nose is formed to its final shape and the flanges are positioned at substantially right angles relative to each other.
