  "textContent": "A tire assembling-disassembling machine is provided which is equipped with a supporting, locking and rotating device (2) for a wheel-rim (C) of a vehicle tired-wheel. The supporting, locking and rotating device (2) comprises a self-centring assembly having a plurality of arms (50, 51, 52, 53) equal to each other uniformly angularly spaced apart from each other and each provided with a respective radial extension (50a, 51a, 52a, 53a), and a respective rubber stopper (50c-53c) at one end thereof, a plate (55) arranged axially sliding along the axis of rotation and articulated to the other end of each of said arms (50-53), a collar-shaped element (54) coaxial and integral with the plate (55) and slidingly engaging with the radial extensions (50a-53a), a motor designed to cause the wheel-rim (C) to rotate about the axis of rotation, and an actuator designed to displace the plate element (55) and the collar element (54) along the axis of rotation. Each arm (50-53) is tubular in structure and comprises a respective rod (50d-53d) which is located therein and has opposite ends articulated one to an end of its respective arm (50f-53f) and the other to said plate element (55)(at 50e-53e), a buffer-carrying jaw (50g-55g) for each arm (50-53) articulated both at the head of each arm (50-53) and at the rod (50d-53d), whereby an articulated parallelogram system is formed at each arm (50-53) in such a way that, although the opening angle between arms (50-53) is changed with respect to said axis of rotation, the stopper-carrying jaws (50g-53g) engage the surface of the wheel-rim (C) in the same attitude.",
