Patent ID: 7300548

Claim:
A method for controlling cross-machine direction (CD) mapping in a web making machine comprising: monitoring a web being produced by said web making machine using sensing equipment; generating at least two web analysis profiles from data representative of said web produced by said sensing equipment using a CD controller; combining a first one of said at least two web analysis profiles with a second one of said at least two web analysis profiles using said CD controller; identifying a developing CD mapping problem from said combination of a first one of said at least two web analysis profiles with a second one of said at least two web analysis profiles using said CD controller; probing at least one CD actuator corresponding to said identified developing CD mapping problem using said CD controller; determining an optimal performance point for said at least one CD actuator from results of probing said at least one CD actuator using said CD controller; and adjusting CD mapping for said at least one CD actuator in accordance with said optimal performance point using said CD controller.
