Method and control device for determining a register error

The invention relates to a process and a device for alignment of sheet material ( ) which is conveyed in one conveyor plane ( ). The sheet material is conveyed on bodies ( ) of revolution and aligned by means of triggerable alignment elements ( ) in the conveyor direction ( ) and perpendicular to the conveyor direction ( ). The alignment elements ( ) are assigned to an alignment unit ( ). The alignment motion necessary for alignment of the sheet material in the conveyor direction ( ) and perpendicular thereto takes placed by separate alignment elements ( ) which can be triggered independently of one another during conveyance of the sheet material ( ) with the process speed.
