Method and apparatus for establishing a range of diameters of the cylindrical working surface of a drum and like devices for grasping, handling, shaping, or other like function, of round or tubular objects, such as tire carcasses and belt and tread packages as employed in the manufacture of vehicle tires. The device includes a plurality of segmented modules adapted to be quickly and releasably manually affixed to a drum or like device in a manner which establishes the range of obtainable diameters of the cylindrical working surface of the existing device. No material structural and/or operational modifications in the basic elements and/or operation of the drum are required. Rather, the existing structural and operational aspects of the existing drum are employed in combination with the present invention.
