Corner bead re-shaping tool

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;
• one vertically adjustable and circumferentially grooved pressure roller, rotatably mounted from the frame vertically above the corner bead travel path, for pressing on the apex of the corner bead while the legs of the corner bead are supported on the plurality of idler rollers;
• and,
• drive receptor means, attached to the pressure roller, the receptor means adapted for engagement by a rotary driver, to enable rotation of the pressure roller by said driver.

• 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 travel path during reshaping;
• comprising:
• a frame, comprising a horizontal single rail part and a vertically extending stanchion part;
• a plurality of spaced apart idler rollers, rotatably mounted along the length of the rail, for supporting the opposing legs of the corner bead during reshaping, said idler rollers aligned along and defining the corner bead travel path, said rollers enabling lateral motion of the legs in a direction transverse to the direction of rotation of the idler rollers and corner bead travel path when the corner bead is pressed downwardly onto the idler rollers by a pressure roller;
• wherein each of said idler rollers comprises a pair of hemispheric shaped half-rollers on opposing side of the rail;
• and,
• a vertically adjustable grooved pressure roller, rotatably mounted on said stanchion part vertically above said corner bead travel path, for pressing downwardly on the apex of a corner bead while the legs of the corner bead are supported on the idler rollers.

• 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;
• 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;
• and,
• drive receptor means, attached to the pressure roller, the receptor means adapted for engagement by a rotary driver, to enable rotation of the pressure roller by said driver.
