<p>A molding drum (10) enabling the inner pressures of folded bladders and a center bladder to be controlled and/or enabling a defective inner pressure to be accurately transmitted. A sensor module (30) having a built-in inner pressure sensor (31) for detecting the pressure in the inner cavity (23, 24, 26) of at least one bladder of the folded bladders (3, 4) and the center bladder (6) is installed in the inner cavity (23, 24, 26). These sensor modules (31) are disposed radially inward of the outer peripheral surface of a drum body (9).</p> |
