<p>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).</p> |
