Abstract
A weldable urethane roller sleeve, and method of fabricatingly installing the same, on site without having to remove the rollers from a machine in order to accomplish installation upon either powered or idler rollers of a roll conveyancing machine of that type typically employed in shear line applications to accomplish movement of reinforcing rods to and from a cutting station, wherein the inside diameter of the roller sleeve which is installed is oversized to be slightly larger than that of the outside diameter of the roller upon which it is installed, thereby enabling the roller sleeve to rotate upon the roller as the roller rotates, which in turn results in reduced wear and impact damage to the roller sleeve since it rotationally displaces with the moving product during the conveyancing thereof.
