An apparatus for supplying sheets to a printing machine having a sliding work plane moving in outward and return runs, so as to subject one or more sheets thereon to printing, a station, in which the work plane pauses, being provided with a gripper for transferring the sheets from the apparatus to the work plane, with the work plane paused in the station. The apparatus includes a gantry bearing a loading plane positioned by a side of the pause station and made vertically mobile from a first variable-height operating position, and a second fixed operating position flanking the pause station. A receiving station of a stack of sheets is positioned by a side of the gantry opposite the work plane, the height of the head sheet of the stack defining a first operating position. A gripper, borne by the work plane, with the work plane in the operating position grips the head sheet of the stack and transfer it onto the work plane. |

1. An apparatus for supplying sheets to a printing machine, the machine comprising: a work plane sliding longitudinally, in an outward run and a return run, such as to subject one or more sheets, arranged thereon, to action of the printing means; at least a station in which the work plane pauses, provided with gripping means for transferring the sheets from the apparatus to the work plane with the work plane pausing in the station; the apparatus comprising: a gantry bearing a loading plane positioned by a side of the pause station and made vertically mobile, by motor means, from a first operating position, height-variable, to a second operating position, flanked to the pause station; a receiving station of a stack of sheets, located by a side of the gantry on an opposite side with respect to the work plane, at a height of the head sheet of the stack defining the first variable operating position; sheet gripping and transfer means, borne by the loading plane, destined, with the loading plane in the first operating position, to engage the head sheet of the stack in order to transfer the head sheet onto the loading plane. |
