Abstract:
A tool for reshaping corner bead used in wall board installation, to increase the included angle thereof, wherein the corner bead has an apex and opposing legs which form said included angle, and, wherein the corner bead travels through the tool along a generally horizontal travel path during reshaping; comprising:a frame;a plurality of spaced apart idler rollers rotatably mounted on the frame along the corner bead travel path, for supporting and guiding the direction of motion of the opposing legs of the corner bead during reshaping, each idler roller comprising a spherical section for enabling motion of the legs in a direction transverse to the direction of rotation of the roller during reshaping of the corner bead;a vertical stanchion, extending upwardly from the frame;a slide block, for supporting a pressure roller, mounted upon the stanchion, and adjustably movable there along;a circumferentially grooved pressure roller rotatably mounted upon the stanchion, for pressing vertically downward on the apex of the corner bead while the legs of the corner bead are supported on said plurality of idler rollers; and,means, mounted on the stanchion and engaged with the slide block, for vertically adjusting the elevation of the slide block and the pressure roller mounted thereon, to vary the spacing between the pressure roller and the idler rollers.
