    Abstract: A register (20; 60) for a processing machine (1) for processing plate-like elements (10) includes a gripping element (21; 22) for placing the plate-like elements (10) in a gripper bar (31) of a conveyor (30) of a processing machine (1) conveying the plate-like elements (10) in a longitudinal direction, an actuator module (201, 202) to drive the gripping element (21; 22), at least one front correction sensor module (7) configured to measure the front position of register marks (12a) printed on a front section of the plate-like element (10) grasped by the gripping element (21; 22). The register (20; 60) includes at least one front pre-correction sensor module (80), placed upstream of the front correction sensor module (7) in the longitudinal direction, the front pre-correction sensor module (80) is configured: to detect the passage of a front transversel edge of the plate-like element (10) in at least two longitudinally spaced lateral axis of detection (P1, P2), one located in front of the other, and to provide measurements to a computation and control unit (40) of the processing machine (1) that is configured: to control the actuator module (201, 202) in order to move the gripping element (21; 22) toward the gripper bar (31) and to activate the gripping element (21; 22) in order to grasp a plate-like element (10). Also a processing machine for processing plate-like elements includes the register. A method for placing plate-like elements within a processing machine is disclosed.
