Patent ID: 7648614

Claim:
Apparatus for controlling cross-machine direction (CD) mapping in a web making machine, said apparatus comprising: a sensor for monitoring said web making machine; and a controller programmed to perform the operations of: monitoring a web making machine; generating at least two web analysis profiles from data representative of said web making machine; combining a first one of said at least two web analysis profiles with a second one of said at least two web analysis profiles; identifying a developing CD mapping problem of misalignment in a cross direction spatial relationship between CD actuators and a CD profile 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; probing at least one CD actuator corresponding to said identified developing CD mapping problem; determining an optimal performance point for said at least one CD actuator from results of probing said at least one CD actuator; and adjusting CD mapping for said at least one CD actuator in accordance with said optimal performance point.
