Zusammenfassung:A system for coordinating the splices in each of the component webs used in making a composite corrugated paperboard web, for example as shown in the accompanying drawing, is described. The system independently measures on a dynamic real time basis the length of each component web (11, 13, 15) between the splicer (18, 31, 55) where it is supplied and a downstream cutoff apparatus (17) where the synchronized splices are cut out in a short length of web in which they are contained. The real time measurement of each component web (11, 13, 15) includes continuous monitoring of web lengths subject to change while running through variable length storage areas (22, 32, 58), and an initialization procedure whereby an initially unknown length of component web (11, 13, 15) in its respective storage is determined. The system also includes a calibration procedure by which the various devices used to measure running web lengths throughout the system are all calibrated to a master device which controls the total web length for each order.
