Method for loading a green tyre for bicycles i n a vulcanisation mould , comprising: - picking said green tyre keeping it hanging by means of a gripping device defining a gripping axis (Z); - handling said gripping device which holds said green tyre up to aligning a geometric axis of rotation (X) of the green tyre with a reference axis (K) of a central body of said vulcanisation mould ; - arranging said green tyre in a radially outer position with respect to said central body of the vulcanisation mould ; - axially positioning said green tyre with respect to the central body so that an axial centreline plane (M) of the green tyre is arranged at an axial reference arranged at a predetermined height along said reference axis (K) of the central body wherein axially positioning said green tyre with respect to the central body comprises handling said central body from a vulcanisation position, in which said central body is arranged within the vulcanisation mould to a gripping position, in which said central body is arranged outside the vulcanisation mould and positioned radially inside the green tyre ; - exerting a thrust action by means of said central body positioned in the gripping position, said thrust action being directed radially outwards on a radially inner surface of the green tyre ; - keeping said green tyre in position on the central body by means of said thrust action; - disengaging said gripping device from the green tyre for releasing said green tyre on the central body with said axial centreline plane (M) centred and positioned in an axial position corresponding to said predetermined height; - handling the central body from the gripping position to the vulcanisation position for vulcanising said green tyre , while keeping said green tyre in position on the central body . - picking said green tyre keeping it hanging by means of a gripping device defining a gripping axis (Z); - handling said gripping device which holds said green tyre up to aligning a geometric axis of rotation (X) of the green tyre with a reference axis (K) of a central body of said vulcanisation mould ; - arranging said green tyre in a radially outer position with respect to said central body of the vulcanisation mould ; - axially positioning said green tyre with respect to the central body so that an axial centreline plane (M) of the green tyre is arranged at an axial reference arranged at a predetermined height along said reference axis (K) of the central body wherein axially positioning said green tyre with respect to the central body comprises handling said central body from a vulcanisation position, in which said central body is arranged within the vulcanisation mould to a gripping position, in which said central body is arranged outside the vulcanisation mould and positioned radially inside the green tyre ; - exerting a thrust action by means of said central body positioned in the gripping position, said thrust action being directed radially outwards on a radially inner surface of the green tyre ; - keeping said green tyre in position on the central body by means of said thrust action; - disengaging said gripping device from the green tyre for releasing said green tyre on the central body with said axial centreline plane (M) centred and positioned in an axial position corresponding to said predetermined height; - handling the central body from the gripping position to the vulcanisation position for vulcanising said green tyre , while keeping said green tyre in position on the central body . <EOS>
