Abstract: A method and apparatus is disclosed for removing any out-of-round condition found in deformable metal cylinders by means of gripping the vertically aligned cylinder successively between a pair of spaced apart endless conveyor belts. The metal cylinders are fed to said pair of endless conveyor belts by moving alignment means which orients each cylinder with the cylindrical axis in a vertical direction and aligns said vertically oriented cylinders in a row while being fed to the cooperating belt members. In a preferred embodiment, the cylinder alignment is accomplished with a vertical gas column while the cylinders are proceeding in a horizontal direction.
