This automated approach helps reduce variations in web smoothness/roughness profiles which can cause a range of imperfections in paper and board products - and in turn cause printability problems. The sensor allows mill personnel to electronically monitor web surface characteristics throughout the entire production process, facilitating immediate corrective action if a product deviates from standards. This increases the yield as less paper/board is rejected, and it also increases paper makers' customer satisfaction as they experience fewer problems with printability.
"Precision FotoSurf saves paper and board makers time and money, and boosts their competitiveness," said Marko Jamsen, Honeywell's EMEA business leader for pulp, paper, printing and CWS. "The solution maximizes productivity by reducing the need for laboratory analysis of smoothness/roughness profiles, minimizes time needed for corrective action when flaws are detected, and ultimately results in higher-quality products with less waste. It provides an entirely new method for diagnosing process problems."
Supporting speeds up to 2,000 m/min., Precision FotoSurf uses a built-in image control unit to manage both camera and illumination parameters. In addition to providing numeric values for surface smoothness and roughness, the sensor displays images of the product surface to determine the root cause of the problem so that corrective action can be taken.
