Tyre changing machine

A method for removing and mounting a tyre from and on a respective rim of a vehicle wheel by means of a head, mounted on an operating arm directed along a longitudinal orientation, a first tool connected to the head and projecting in a first direction, and a second tool connected to the head, wherein mounting and removal are carried out by interaction of the first and the second tool, respectively or vice versa, with the tyre during the step of rotating the rim about its axis,

• the method being wherein it comprises a step of rotating the second tool about an axis of tilt transverse to the longitudinal orientation in order to tilt the second tool between a first position, where it projects in a second direction, opposite to the first direction, and a second position, where it projects in a first direction, wherein, to remove the tyre, the second tool is positioned at the first position and, to mount the tyre, the second tool is positioned at the second position, or vice versa.

An operating arm for a machine configured to remove and mount a tyre from and on a respective rim of a vehicle wheel, the operating arm being directed along a longitudinal orientation and comprising:

• a head supported by the operating arm;
• a first tool and a second tool, wherein the first tool is connected to the head and projects in a first direction and the second tool is connected to the head and, in a first operating configuration of the head, is disposed in a first position where it projects in a second direction, opposite to the first direction,
• wherein the second tool is pivoted to the head to rotate about an axis of tilt transverse to the longitudinal orientation to move from the first position to a second position, corresponding to a second operating configuration of the head and tilted upside down relative to the first position, to project in the first direction.
