Abstract
A radially expandable building drum, in which is intended for manufacturing an adapter for mounting a tire on a wheel rim, includes a central shaft, a first set of segments, and a second set of segments. All of the segments are arranged circumferentially around the shaft to form a generally cylindrically shaped external face of the drum. The segments of the first set and the segments of the second set face one another axially. The drum is structured to allow a different radial expansion of the segments of the first set in relation to the segments of the second set, between two working positions.
