摘要：The invention relates to a device (2) for transferring an elastomer ring forforming a tyre tread (4), comprising an annular structure (20) on which a plurality ofgripping modules (3) is peripherally arranged, each of the modules comprising: two liftingfingers (30) for engaging the radially inner surface of the tread (4), said fingers beingaxially mobile in opposite directions in relation to a plane of symmetry (PP') and radiallymobile between a plurality of predetermined radial positions; and a bracing sole (31)which moves radially under the action of at least one bracing cylinder (310), and comesinto contact with the radially outer surface of the tread (4). The bracing cylinders (30) arepressure-regulated over a plurality of nominal pressures which are different from eachother such that, at a given nominal pressure, the application pressure exerted by thebracing sole (31) on the radially outer surface of the tread (4) is constant irrespective ofthe radial position of said bracing sole.
