The machine (1) has a base (3), a fixed arm (4) connected to the base (3) and defining an inverted "U"-shaped configuration having a free end. A conventional bead extractor (5) is connected to the free end of the fixed arm (4), which overlies a rotatable tire-supporting platform (6) driven by a drive unit (13). The rotatable platform (6) is mounted on a plate (11) having opposite sides provided with bearings movably connected to a pair of parallel guide elements (18) fixed to the sides of the base (3). A fine-adjustment mechanism (14-16) is provided for positioning the plate (11) and the rotatable platform (6) with respect to the bead extractor (5) and the fixed arm (4) for accommodating a wide range of different sizes of wheels and tires. <IMAGE> |
