A debeading device for tire changing machines includes a swing arm having a hinging end hinged to a base of a tire changing machine and swinging in a swing plane between an active debeading position toward the base and an inactive position away from the base; a debeading tool supported at a free end of the arm, opposite to the hinging end; an actuator for reciprocatingly rotating the arm between the active and inactive positions, which includes an externally screw-threaded member supported by the base and rotatably actuated by a motor and screwingly/unscrewingly engaged in a matingly threaded hollow member associated with the arm.

A tire changer apparatus includes: a base, a wheel-holder configured to rotate a wheel around a rotation axis, a first and second column emerging from the base, a first device having an extensible arm carrying a tool, a second device having a respective extensible arm carrying a tool opposite the tool of the first device with respect to an ideal middle plane of the apparatus. The tire changer apparatus further includes: a first and a second bar respectively connecting the arms of the first and second devices, a transmission which connects the first and the second bar to synchronize the movement of the arms of the first and second devices.

A tire mounting apparatus includes a rim positioning mechanism, a wheel support mechanism and a mounting frame that are disposed on a base in sequence, and a tire pressing mechanism disposed on the mounting frame. The rim positioning mechanism is configured to position a hub of a rim. The wheel support mechanism is configured to support a side peripheral edge of a wheel. The tire pressing mechanism is configured to press a side peripheral edge of a tire for pressing a bead of the tire into the rim. The operation is simple and labor-saving. The tire mounting efficiency can be improved and the labor intensity can be reduced.

Machine for unseating a tire bead from a wheel, comprising a stand designed to rest on the ground, a bearing plate for the wheel, and a bead unseating tool which is connected to a tool bearing structure mobilely mounted to the stand. The machine comprises a pneumatic actuator for setting the tool bearing structure in motion in order to operate the tool, and a shock absorber connecting the tool bearing structure to the stand in order to damp the movement of the tool bearing structure, particularly at the moment at which the tire bead unseats from the rim of the wheel.

A mount and demount head configured as a housing affixed to a shaft of an OEM tire machine with a semicircular shaped shaft affixed to the housing. The shaft has a bulbous protrusion on a bottom end of the shaft with specific tapers. The shaft and the bulbous end have a flattened portion for following the contour of the rim. On the upper side of the bulbous end is the narrow semicircular shaft with a tapered top end, tapered to a widened shaft, which is affixed to the housing. A non-metallic insert is preferably inserted into a void in the flattened portion of the narrow semicircular shaft and bulbous end to protect the rim surface. Clamp adapters are used to clamp and hold small wheel assemblies whereby the clamp adapters are inserted over the OEM clamps to extend the clamp capability of the OEM tire machine.
