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.

A radially expandable building drum for manufacturing an adapter for mounting a tire on a rim, the drum comprising:
- a central shaft;
- a first set of segments;
- and
- a second set of segments,
- wherein the segments of the first set and the segments of the second set are rigid and elongated elements arranged circumferentially around the central shaft to form a generally cylindrically shaped external face of the drum,
- wherein the segments of the first set and the segments of the second set are axially juxtaposed,
- wherein the segments of the first set and the segments of the second set are structured to enable a different radial expansion of the first set relative to the second set, between two working positions, and
- wherein an axially internal face of the segments of the first set includes teeth that axially interpenetrate with teeth of an axially external face of the segments of the second set.
