A printing machine includes a circular contour printing table which has a plurality of object-stations regularly distributed around its periphery each adapted to receive an object to be printed and which, rotatable stepwise about an axis, moves the object-stations successively to a loading station, to a plurality of workstations each including a printing system, and to an offloading station. A system for turning over the objects includes a first transfer arm which picks up an object on the printing table and puts it down on an overturning shovel, turns it over and puts it down at a receiving station. A second transfer arm picks up the turned-over object at the receiving station and puts it back down on the printing table.
