Claim Text:
1. A folding and gluing machine for the production of cartons from blanks, the blanks having an external face, the blanks circulating flat in a plane of displacement and with the external face underneath, comprising at least one working device for working on the external face of the blanks, the working device comprising: a first turnover device for turning over the entire blank in order to position the external face uppermost, by displacing each of the blanks along a trajectory that is perpendicular to the plane of displacement of the blank before the turnover, the trajectory describing a first upwardly-oriented half-loop; a first transport device placed downstream of the first turnover device configured to displace each of the blanks with its external face uppermost; an action device for accomplishing at least one of the functions comprising, during the displacement of the blank by the first transport device, printing the external face of each of the blanks and checking the external face of each of the blanks; a second turnover device placed downstream of the first transport device which turns over the entire blank in order to reposition the external face underneath, by displacing each of the blanks along a trajectory which is in a plane that is perpendicular to the plane of displacement of the blank before the turnover, the trajectory describing a second upwardly-oriented half-loop; and wherein the first turnover device, the first transport device and the second turnover device displace each of the blanks along a trajectory within a plane of the machine that is perpendicular to the plane of displacement of the blank before the turnover; and a second transport device downstream of the second turnover device, which brings the entire blank to the level of the initial plane of displacement in which the blank was circulating before the first turnover device.
