Abstract
A tyre changing machine placed on a supporting surface comprises: a wheel-holder unit rotatable about a horizontal axis of rotation; a floorplate extending along a horizontal placement surface to receive and support the wheel; a drive system for driving the wheel-holder unit along the axis of rotation; a tool-holder turret supporting a tool in a working position where it interacts with a wheel tyre; a connecting member arranged on the floorplate in a fixed position; a tool-holder arm fixable to the floorplate through the connecting member to project from the floorplate transversely to the placement surface and to hold a further tool in an operating work position where it can interact with the tyre.
