Abstract
A group for assembling, disassembling and bead releasing of a tire (2) onto and from a wheel-rim (3) supported mounted for rotation about an axis and having at least a carriage or slid (4) displaceably mounted on guides (5) extending parallel to the axis of rotation of the wheel-rim (3), an arm or upright (6) extending in a transverse direction with respect to the said axis of rotation and having one end thereof supported by the slide or carriage (4) and its other end provided with a bead releasing tool (7, 8) that can be arranged so as to have its working front or edge (107, 108) facing towards the same side. First driving means (9), designed to cause the arm (6) to rotate about a longitudinal axis (x--x) for positioning the bead releasing disk (7) and the tool (8) with respect to the sides of the tire (2), and second driving means (10), designed to effect the rotation of the said arm (6) about at least one axis (y--y) extending transversely with respect to said longitudinal axis, are also provided, thereby lifting or lowering, upon control, the bead releasing disk (7) and the tool (8) with respect to the displacement of the slide or carriage (4) along the guides (5) for overtaking the wheel-rim (3) or tire (2).
