Abstract
To obtain and expedite an automatic engagement and disengagement of the bladder with respect to the relative operating mechanism, in particular in presses used for curing pneumatic tires, the movable clamp and the fixed clamp, respectively, which block the beads of the flexible, elastically deformable sleeve constituting the bladder, comprise annular grooves, coaxial with the axis of the bladder, which, in operation interact with the heads of a plurality of pegs situated in the head to be assembled to the movable clamp and in the body of the support to be associated to the fixed clamp, the pegs being radially movable in both senses between two positions, i.e. a work position in the operating condition and a rest position in which said pegs are completely collapsed into the body of said head and of the support so as to allow the axial insertion of the bladder on the mechanism and its removal therefrom.
