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).
A group 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 and having at least one carriage or slide 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 slide or carriage and its other end provided with a bead releasing tool, wherein said bead releasing tool can be arranged so as to have its working front facing towards the same side, and wherein it comprises 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 lifting or 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 or slide along said guides to overtake said wheel-rim or tire.
A method of bead releasing and disassembling a tire from a wheel-rim mounted on a rotatable mandrel of a tire-disassembling machine having a slide displaceable on guides parallel to the axis of rotation of said wheel-rim, an arm extending from said slide, a bead releasing disk and a removing tool carried by said arm and provided with working fronts that can be positioned so as to be facing towards the same side, characterised in that it comprises the following steps:
