Method and apparatus for controlling cross-machine direction (CD) controller settings to improve CD control performance in a web making machine

摘要: A web making machine (108) is monitored to identify at least one cross-machine direction (CD) actuator (126) that developing local mapping problems. The identified CD and a segment of surrounding actuators are probed determine performance curve (227) for the actuator. center an insensitivity region selected as optimal alignment setting with being updated. Global smoothing may also be accomplished by probing global smoothness factor generate corresponding then similarly used select value factor.
