Abstract: A method and machine for removing a tire, fitted with a rigid inner run-flat ring, from a relative rim, whereby, once the rim and the tire are fixed onto a turntable having a central hub and rotating about a first axis coaxial with the hub and the tire, a bead of the rigid inner ring is engaged and moved axially outwards of a relative flange of the rim by a hook carried by a lever hinged to the hub and oscillated, with respect to the hub and in a radial plane of the turntable, about a second axis perpendicular to the first axis and rotating about the first axis.

Abstract: A machine for assembling and disassembling a tyre fitted with a rigid inner run-flat ring, wherein the machine is a tyre removing machine having a turntable; a tool column located alongside the turntable and having a guide located alongside and parallel to the turntable; a slide mounted to run along the guide; and an actuating device for moving the slide along the guide; the tyre removing machine having tooling defined by a first tool fitted to the turntable to support the tyre and the rigid ring, and by a second tool fitted to the slide and movable with the slide along the tool column to engage the rigid ring and move the rigid ring with respect to the tyre.

Abstract: A method and device for manufacturing curing bladders (2), whereby a curing mold (3) defines, via a first (4) and second (5) half mold and an inner core (6), an inner molding chamber (7) and an outer injection chamber (34) communicating with the inner chamber (7) and consisting of a variable-volume chamber of an injection cylinder (59); the outer chamber (34) being fed with a mass (35) of heated uncured rubber which is injected into the inner chamber (7) with the mold (3) closed and, when cured, is extracted from the mold (3) by opening the inner chamber (7) and extracting the inner core (6).

Abstract: A method and device for manufacturing tire forming bladders (2), whereby a curing mold (3) defines, via first and second half molds (4, 5) and an inner core (6), an inner molding chamber (7) inside which a precured reinforcing ply (72) is optionally inserted; the mold (3) having an outer injection chamber (34) communicating with the inner chamber (7) and consisting of a variable-volume chamber of an injection cylinder (65); the outer chamber (34) being provided with a mass (35) of heated uncured rubber, which is injected into the inner chamber (7) with the mold (3) closed and, when cured, is extracted from the mold (3) by opening the inner chamber (7) and extracting the inner core (6).
