Abstract:
A machine for mounting and removing a special tire on and, respectively, from a wheel which has a first, inner rim edge for retaining an inner bead of the special tire and a second, outer rim edge for retaining an outer bead of the special tire, the machine comprising: a floor-mounted turret extending along an axis thereof, a coupling unit supported at said turret for coupling and turning the wheel, in a wheel lying plane, during tire mounting and removal; a pusher device, supported at said turret for pushing transversally to said wheel lying plane, either at a first pushing position located at the outer bead of the tire or at a second pushing position located at the inner bead of the tire; position adjustment means for positioning said pusher device at said first and second pushing positions; a lever arrangeable for operation in cooperation with said pusher device to lift a bead flap of the tire from outer rim edge of the wheel; a presser arranged so as to operate in cooperation with said pusher device for pressing at a position at the inner bead of the tire which is substantially diametrically opposed to the second pushing position of the pusher device; and a complementary presser arranged so as to operate in cooperation with said pusher device for pressing at a position of the outer bead of the tire which is substantially diametrically opposed to the first pushing position of the pushing device.
