The Metso PQV system helps to improve runnability and ensures the best quality for the customer through an integrated web break analysis and web inspection system.The new system in Simpele will replace two separate systems on the machine and provide the ability to detect and follow possible faults and interrelated breaks back to their source. A web break analysis system is used to find the origins of web breaks, and a web inspection system is in charge of demanding board structure and surface quality analyses.Metso Process and Quality Vision integrates web break analysis capabilities and web quality inspection using high-frequency camera images to produce a continuous view of the moving web. Three different geometries are typically used in web inspection system installations. Transmission geometry is used to detect flaws in the sheet, high angle geometry is used for surface defects and low angle geometry is used to detect coating imperfections.The web break analysis camera images and web inspection information are combined into a common operator interface.Simpele mill produces folding boxboard. The mill's board machine, rebuilt by Metso in 2011, has an annual capacity of 300,000 tons.
