Claim:
An apparatus for assembling, disassembling and bead releasing of a tire onto and from a wheel-rim carried on a support mounted for rotation about an axis, comprising at least one carriage means displaceably mounted on guides extending parallel to the axis of rotation of said wheel-rim, an arm extending in a transverse direction with respect to said axis of rotation and having one end thereof supported by said carriage means and its other end provided with a bead releasing tool, wherein said bead releasing tool is arranged so as to have its working front facing, in use, towards said wheel-rim on said support, and further comprising first driving means designed to cause said arm to rotate about a longitudinal axis to position said bead releasing tool with respect to the sides of said tire, and second driving means designed to cause said arm to rotate about at least one axis extending transversely to said longitudinal axis thereby alternately lifting and lowering, upon control, said bead releasing tool with respect to said wheel-rim or tire in sequence with respect to the displacement of said carriage means along said guides to induce the tire bead to step or pop over said wheel-rim or tire.
