The invention relates to an automatic tire manufacturing machine (1) comprising a building zone (2) for producing on a drum (6) a carcass block (3) comprising a carcass ply (4) with carcass reinforcements (5). ), a finishing zone (20) for producing a crown block (21) comprising a tread (22), a shaping system (30) for causing radial expansion of the carcass block (3) in order to give it a shape toroidal, an assembly zone (40) for assembling the crown block (21) on the carcass block (3), a polarization system (50) for associating with the carcass block (3) a polarization structure (51) provided with polarization reinforcements (52) arranged to interact, during shaping, with the carcass reinforcements (5) in order to modify the angular orientation of said carcass reinforcements (5) with respect to the circumferential direction (C6) of the drum (6) ), and an automatic control unit (60) thus making it possible to manufacture a ba ndage polarized crown by providing that the realization of the crown block (21) takes place in masked time compared to the preparation of the carcass block (3).
