The subject of the invention is a feeder wherein it includes at least one fixed magazine (10) for storing stacked sheet elements (8), one press roller (11) cooperating with a device (4) for continuously feeding each flat support (2) to be provided with one sheet element (8), at least one member (22) for picking up and laying down the sheet elements one at a time by means of suction, and means (12 to 17) for supporting and actuating said picking up member (22), said means being disposed so as to provide said member with at least a partly hypocycloidal trajectory (30, 30') so that two points (31, 32) for turning back the hypocycloid coincide with firstly the point for picking up a sheet element (8) in said magazine (10), and secondly with the point for transferring said element (8) to said press roller (11).
