A system for coordinating the splices in each of the component webs used in making a composite corrugated paperboard web independently measures on a dynamic real time basis the length of each component web between the splicer where it is supplied and a downstream cutoff apparatus 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 includes continuous monitoring of web lengths subject to change while running through variable length storage areas, and an initialization procedure whereby an initially unknown length of component web 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. Accuracy of the system is further enhanced by independently monitoring the response time of each splicer to its activating control signal and adjusting, as necessary, the timing of the control signal for measured variations in response time.
A method for synchronizing the location of splices defining changes in each of the component webs of an advancing double face paperboard web formed from three component web sources each including a splicer, wherein a first liner component web is directed from its source, through a first variable length liner web storage, to a single facer;
A method for synchronizing the location of splices in the component webs of a composite web forming system in which the composite web is formed by joining the component webs from multiple web sources, each of said web sources including a web splicer and a variable length web storage between the splicer and a downstream point of web joining, at least one of said component webs being subject to compression in length by a known compression factor prior to joining, and the system including a downstream cutoff apparatus operable to cut out a selected length of the composite web, said method comprising the steps of:
An apparatus for synchronizing the location of splices in the component webs of a composite web forming system in which the composite web is formed by joining the component webs from multiple web sources, each of said web sources including a web splicer and a variable length web storage between the splicer and a downstream point of web joining, at least one of said component webs being subject to compression in length by a known compression factor prior to joining, and the system including a downstream cutoff apparatus operable to cut off a selected length of the composite web, said apparatus comprising:
