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

Abstract: The CD (cross-machine direction) profile of a web of material being produced is monitored and controlled to update CD control settings on-line (i.e. while the processing is operating). Thus, changes in the operation of a machine manufacturing the web can be corrected before significant profile deviations from a desired CD profile target result. Detected variances in the CD profile that satisfy a search criteria initiate searches for improved CD control settings. A CD control performance indicator representative of effectiveness of a CD control is established, and CD mapping settings related to the CD control performance indicator are selected. Improved CD mapping settings are selected online, during sheet manufacture, which produce an improvement in said CD control performance. The CD control recognizes CD actuator mapping misalignments, determines improved CD control settings and applies the improved CD control settings to improve upon or correct mapping misalignments.

Abstract: The CD profile of a web of material being produced is monitored and controll ed to update CD control settings on-line so that changes in the operation of a machine manufacturing the web can be corrected before significant profile deviations from a desired CD profile target result. Detected variances in th e profile that satisfy a search criteria initiate searches for improved CD control settings. The CD control recognizes CD actuator mapping misalignment s, determines improved CD control settings and applies the improved CD control settings to fine tune a CD controller and thereby improve upon or correct mapping misalignments. The CD control also recognizes non-smoothness of the setpoints of the CD actuators and controls the smoothness of the setpoints. Recognition and correction of either CD actuator mapping misalignments or CD actuator setpoint smoothness or both can be performed by the automated optimization of the present application.
