ABSTRACT:
A tire component building machine includes a rotatable hub with a plurality of circumferentially spaced circular segments each having the same radius of curvature and each including a stem mounted on the hub for radial movement. A stud passing through and removably secured to each stem includes a projecting portion engaging a spiral cam, one end of each stud being exposed on a common side of the stems whereby each stud may readily be removed and the segments replaced by another set of segments each having another same radius of curvature. A drive assembly mounted on the hub rotates the hub and cam relative to one another radially to expand and contract the segments. In addition, the maximum expansion of the drum may be precisely regulated by an adjustable stop. A gap shield is provided to present a continuously firm circular work surface.
