Abstract
The register insertion apparatus for sheet-fed embossing machines with position sensors (S1, S2, S3) for detecting printing marks (P1, P2, P3) of a sheet (5), comprises a register plate (15) capable of being pivoted down as feeder table with ventilation openings (20) and vacuum feed lines (21) to a suction apparatus (22) and front stops (12), which are capable of being lowered and actuators (L1, L2, L3) for positioning the register plate in X-direction and in Y-direction. With a register controller (11) the register plate (15) is pivoted down, a gripper bar (8) is brought up to it, the register plate pivoted up again, then a sheet (5) is fed-in and stopped at the front stops (12). Thereupon the register plate is evacuated for sucking on and fixing the sheet on the register plate. Then the positions of the printing marks (P1, P2, P3) are detected by the position sensors, from this the register correction values (X1, X2, Y3) are calculated and the register plate by means of the actuators (L1, L2) in X-direction and by means of the actuator (L3) in Y-direction is moved into the desired position (P1S, P2S, P3S). Then the sheet is gripped by the gripper bar, the register plate (15) is v…
