ABSTRACT:
A building drum (1) wherein two half drums (9, 10) are moved equally and oppositely along the same axis (6) between a parted idle position and an adjacent forming position. Each half drum (9, 10) supports an annular end element (29) of a tubular, axially deformable forming module (28), an intermediate tubular body (30) which is defined by a number of side-by-side, partially superimposed metal blades (40) connecting the two annular end elements (29) and movable to and from a deformed position wherein the blades (40) define a toroidal body (48) substantially corresponding negatively in shape to that of a finished tire (49).
