Beschreibung
Zusammenfassung:	The present invention provides a method and apparatus ( 20 ) for controlling a registration between a target point ( 22 ) on a moving web ( 24 ), and a production outcome provided by a production operation. A method aspect can include a transporting of the web ( 24 ) along a movement direction ( 26 ) past a reference detector ( 30 ), and a detecting of at least a first reference point ( 50 ) on the web ( 24 ). The target point ( 22 ) can be designated by employing at least the first reference point ( 50 ). The web is transported past a speed-sensor ( 32 ), and the speed-sensor can measure a web speed of the moving web ( 24 ) to provide an output of web speed data. The web speed data is integrated over time to determine a web-length which has been transported past the speed-sensor ( 32 ). The production outcome is actuated at a production-device ( 34 ), and the actuating of the production outcome can be adjusted to occur after a reference-length of the web ( 24 ) has been transported past the speed-sensor ( 32 ).
