APPARATUS FOR MOUNTING A TYRE ON A RIM

An apparatus (1) for mounting a tyre (P) on a respective rim (C) of a wheel (R) of a vehicle comprises: a frame (100); a chuck (3) which rotates about an axis of rotation (R1); a working tool (2) movable relative to the frame (100) towards the wheel (R); a bead seating device (4) configured to generate an air flow to be injected between a flange of the rim (C) and a bead of the tyre (P). The bead seating device (4) is movable relative to the chuck (3) along a transverse orientation (T), perpendicular to the axis of rotation (R1), between a rest position (P1), in which the bead seating device (4) is spaced from the rim (C), and a working position (P2), in which the bead seating device (4) is interposed between the flange of the rim (C) and the bead of the tyre (P). The bead seating device (4) includes a rigid element (401), an injection nozzle (403) and a duct (404). At the working position (P2), the bead seating device (4) is operatively constrained rigidly to the frame (100) and is configured to remain independently and fixedly stationary at the position (P2), even when subjected to a force generated by the air flow.
