Abstract
Tire-making apparatus (20) defining an outer or inner circumference (18) to serve as a forming surface or as a circumference-engaging surface, respectively, utilizes a frame (16) having a central axis (52) and a plurality of multi-sectional segments (28) which are moveable radially with respect to the central axis and include arcuate surfaces which collectively define the apparatus circumference. Each segment includes a primary section (60) and a secondary section (62) which flanks the primary section. The primary and secondary sections are connected so that as the segments are moved radially of the central axis, the primary and secondary sections move relative to one another along the circumference of the apparatus to help maintain the uniformity, or roundness, of the surface of the circumference collectively defined by the segments.
