Abstract: Typically quality at paper machines online is measured with a scanning gauge. This paper presents two approaches of irregular scanning to improve the diagnostics and control of the variations of the paper web: changing the scanning routine based on detection of variations degrading CD/MD separation performance, and continuous path optimization. A 2D estimation method that is applied to both regular and irregular scanning is described.
