• the register plate 15 is pivoted 15 'for the passage of a gripper bar 8, which is connected to a drive chain 32 of the embossing machine 1. Then, the gripper bar is stopped and the register plate swung open again and fed a sheet 5 of a feeder 3 on the register plate until it is stopped at the front stops 12. Then the register plate is evacuated to suck and fix the sheet 5 on the register plate 15. Subsequently, the front stops 12 are lowered (12 1 ) and the index plate is advanced by the actuators Ll, L2 in the X direction and thereby the sheet 5 on the

Then, the position of the print marks P1 5 P2 is rapidly detected upon initial advancement of the register plate, and there is more time for the calculation of the residual displacements Xl 5 X2 by the controller 11 5 so that the register plate 15 goes directly to the target positions PlS, P2S with total displacements X4 5 X5 can be moved and the movement of the actuator L3 in the Y direction can begin earlier. Analogously, Y is also moved directly into the position P3S with a total displacement Y6 in the transverse direction Y.
