A tyre shaping drum comprising two bead engaging systems (4) mounted in mutually facing positions on a central shaft (5). Each of the bead engaging systems comprises a support (16) axially movable relative to said shaft. An assembly mounted on each support comprises a plurality of rigid segments (10) and a resilient membrane (20) enclosing same. Each of the rigid segments is tiltably mounted on said support about a hinge (14) of which the axis is perpendicular to a radial plane. A seat provided on each assembly is arranged axially within said hinges, and said hinges form a ring around said support. Said resilient membrane is attached to the support axially within and outside the ring of hinges. |
