Abstract:
1. A tire mounting-demounting machine including a base, a wheel carrier support rotatable around a rotation axis, on which a rim or a tired wheel is removably fixable, at least one column rising from said base, and a bead breaker group including a single support arm displaceable, in use, in two substantially parallel bead breaking directions along one bead breaking axis, and comprising a pair of bead breaker rollers supported on substantially opposite sides with respect to the single support aim, thereby defining opposite work fronts directed away from the single support arm, each bead breaker roller having one work front only, the work front of a first bead breaker roller of said pair of bead breaker rollers being permanently directed towards only one bead breaking direction of said two bead breaking directions, whereas the work front of a second bead breaker roller of said pair of bead breaker rollers is permanently directed towards only the other bead breaking direction of said two bead breaking directions, said single support arm supported by said column and projecting so as to extend transversely with respect to the rotation axis of said wheel-carrier support, the bead-breaking directions extending along the bead breaking axis and being substantially parallel with respect to said rotation axis.
