The quality control at paper machine is based on the on-line scanning basis weight measurements. However, due to the scanning the uncertainty of a basis weight estimate is rather large and the representativeness rather poor. Therefore, the potential of the web inspection system (WIS) which measures the light transmittance of paper online was evaluated in quality control and diagnostics of paper. The target paper was measured with the on-line web inspection system, the on-line quality control… CONTINUE READING
