ABSTRACT:
An automatically actuated tire mounting and demounting machine flexibly equipped for mounting tires on rims of all configuration, said machine comprising coordinated working elements which mount a resiliently composed tire on a rim and simultaneously inject air pressure into the tire interior as the tire is at the final steps of its mounting process. Moreover, the machine incorporating the subject invention comprises a base member upon which a tire mounting block is affixed, this tire mounting block being so structured to receive a bare tire rim in a horizontal position for installation of the tire member thereon. Located above the tire mounting block are a pair of parallel and downwardly depending complementary working arms, with free-rolling members thereon of cylindrical configuration and variable diameters which latter arms move in complementary opposing arcuate movements circumferentially above and around the tire rim, but inside the tire bead, so as to facilitate the mounting of the tire on the rim in circumferential fashion. Within the tire mounting block are dual air injection systems which function to induce air into the tire interior simultaneously with the process of mounting the tire as described above.
