A machine for packing a tile or a stack of tiles with one or more cardboard blanks, it comprises: a first store containing cardboard blanks; a folding station for folding a cardboard blank against a tile or a stack of tiles; transfer means for transferring a cardboard blank from the first store to the folding station along a pathway; a printing head arranged along the pathway and activated in phase relation with the transfer means such as to print on the cardboard blank when the cardboard blank is positioned along the pathway between the first store and the folding station; characterised in that the first store provides at an outlet thereof a cardboard blank which is flattened and orientated in such a way that the larger side develops substantially horizontally and the smaller side is inclined by an angle with respect to a vertical plane; wherein the printing head is arranged below the first store and above the folding station; comprising: a frame; an aspirating mouth; a collecting member which bears the aspirating mouth and which is hinged to the frame such as to collect the cardboard blank from the outlet of the first store, such as to rotate it up until it assumes a first vertical position and to release it; wherein the transfer means comprise gripping means that are vertically mobile such as to collect the cardboard blank from the collecting member, in order to lower the cardboard blank into a second vertical position so that the blank can be printed upon by the printing head and in order to further lower the cardboard blank, once printed, into a third vertical position which is at the folding station, in order to be folded against a tile or a stack of tiles; wherein the gripping means comprise: a first pliers, a first horizontal abutting surface, a first pliers support which bears the first pliers and the first horizontal abutting surface, the first horizontal abutting surface being arranged with respect to the first pliers in such a way that when the jaws of the first pliers are open the cardboard blank can be arranged in such a way that the lower edge thereof is interposed between the jaws of the first pliers and can abut the first horizontal abutting surface; a second pliers, a second horizontal abutting surface, a second pliers support which bears the second pliers and the second horizontal abutting surface, the second horizontal abutting surface being arranged with respect to the second pliers in such a way that when the jaws of the second pliers are open the cardboard blank can be arranged in such a way that the lower edge thereof is interposed between the jaws of the second pliers and can abut the second horizontal abutting surface; the first pliers support and the second pliers support being positionable between them in such a way that the first horizontal abutting surface is aligned to the second horizontal abutting surface when the first pliers and the second pliers are gripping the lower edge of the cardboard blank arranged in the first vertical position, such that a temporary opening of the jaws of the first pliers and the second pliers can determine the abutting of the lower edge of the cardboard blank against the first horizontal abutting surface and against the second horizontal abutting surface with a consequent orientation of the cardboard blank such that the larger side thereof is parallel to a horizontal plane.
