Abstract: A system for transferring supports for objects which can be stacked and unstacked between a conveyor and a machine for printing the objects, characterized in that it includes: a mobile transfer table which has two locations each adapted to receive an object support and which is adapted to occupy a plurality of positions, first drive elements adapted to drive the transfer table vertically up and down, and second drive elements adapted to advance or withdraw the transfer table horizontally and simultaneously to transfer a support containing objects and an empty support or to withdraw the empty transfer table to a position awaiting a new support.

Abstract: A feeder system for feeding objects to object-carriers of a machine for processing the objects, in particular a printing machine, includes a reciprocating finger for pushing each object directly towards an object-carrier to place the object on the object-carrier; the finger being carried by a reciprocating carriage slidably mounted on a chassis and rotatably mounted on the carriage so that it can occupy at least an operational position in which it can push an object when it is moved and a retracted position in which it can avoid an object when it is moved.

Abstract: 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.

Abstract: A stack support loading and/or offloading system includes a carriage mobile in translation between a retracted position in which the carriage is moved away from the machine and an advanced position in which the carriage is close to the machine, the direction of movement of the carriage being substantially horizontal. An arm pushes or pulls a support, having at its free end a shape suitable for the support to be moved, and mounted on the carriage and articulated about a substantially vertical shaft between a deployed position in which the free end of the arm is on the trajectory of a support and a retracted position folded toward the carriage. A spring return system spring-loads the arm toward its deployed position. Applications include a loading and offloading station, for example for a machine for printing compact discs.
