An improved apparatus and method are provided for spin-forming tapered rollers, including but not limited to conveyor rollers, drum pulleys, web feed rollers and the like, from a tube without using any internal or external supports between the ends of the tube. The apparatus includes first and second clamp assemblies which support opposite ends of the tube. A rotation structure rotates the tube as a plurality of rollers engage the outer surface thereof. The rollers move between the clamp assemblies to alter the outer diameter of the tube during travel. A controller controls the urging of the rollers against the tube and controls the movement of the rollers between the clamp assemblies.
