Method for mounting and demounting a tyre to and from a wheel rim

A method for mounting a tyre on a rim of a vehicle wheel or for demounting a tyre from a rim of a vehicle wheel, in which a mounting/demounting device is supported by a post of a tyre mounting/demounting machine and is movable at least in a first direction, which is substantially parallel with respect to a rotational axis of the vehicle wheel, and in a second direction, which is substantially perpendicular with respect to said rotational axis of the vehicle wheel, comprising the steps of:

• (a) determining an initial reference position for the mounting/demounting device, said initial reference position being proximal to an edge of the wheel rim;
• (b) linking the position of the mounting/demounting device with the initial reference position;
• (c) entirely manually adjusting the position of the mounting/demounting device with respect to only the first direction;
• (d) continuously detecting the position of the mounting/demounting device with respect to both of said first and second directions;
• and
• (e) by a controller, at the same time as step (c), continuously and entirely automatically adjusting the position of the mounting/demounting device with respect to the second direction only, in dependence of the initial reference position and the manually adjusted position of the mounting/demounting device in the first direction.

A method for mounting a tyre on a rim of a vehicle wheel or for demounting a tyre from a rim of a vehicle wheel, in which a mounting/demounting device is supported by a post of a tyre mounting/demounting machine and is movable at least in a vertical direction, which is substantially parallel with respect to a rotational axis of the vehicle wheel, and in a horizontal direction, which is substantially perpendicular with respect to said rotational axis of the vehicle wheel, comprising the steps of:

• (a) determining an initial reference position for the mounting/demounting device, said initial reference position being proximal to an edge of the wheel rim;
• (b) linking the position of the mounting/demounting device with the initial reference position;
• (c) entirely manually adjusting the position of the mounting/demounting device with respect to only the vertical direction;
• (d) continuously detecting the position of the mounting/demounting device with respect to said vertical direction and said horizontal direction;
• and
• (e) by a controller, at the same time as step (c), continuously and entirely automatically adjusting the position of the mounting/demounting device with respect to the horizontal direction only, in dependence of the initial reference position and the manually adjusted position of the mounting/demounting device in the vertical direction.
