One of two paperboard machines at Metsä Board’s Husum mill, which use both of SmartAdvisor quality systems


especially its reliability and the high performance of its linescan technology. Mill operators had found SmartAdvisor in particular to be highly effective in machine troubleshooting, using its long- term video buffer to review production over a period of four to five days. In addition, SmartView had proved to be easy to integrate into its production and maintenance processes. After consultation between


Ametek Surface Vision and Metsä Board, a SmartView 7 system was installed on the EM1 line, using fast 4K linescan cameras. These were positioned to inspect both sides of the board in a brightfield


and darkfield arrangement. This installation allows the use of Synchronized View technology for better defect detection. It is especially effective if the defect visibility is affected by the level of reflection.


Delivering high- performance results The SmartView system delivered effective inspection of board, coated board and extrusion- coated material. Subtle streaks in the coating


process were detected at an early stage, allowing action to be taken immediately to avoid scrap material. Repeating defects detected by SmartView proved


highly useful in rapidly identifying the cause, allowing the issue to be remedied quickly. Coating defects such as coating


voids, streaks, blade scratches and dents are highly relevant to product quality, since the product often goes into the luxury packaging segment, where defect- free appearance is critical. All inspection data provided by the SmartView system is transferred through an open interface to the centralised mill system. This allows the thorough analysis of defect occurrences and trends and permits detailed analysis of the production quality. An operating technician from Metsä Board said: “We have been
