Quality Management performs comprehensive quality control using information from various sources including the laboratory, Quality Control System, Distributed Control System, and Web Imaging System.
Bar codes may be used to efficiently identify paper and process samples in the laboratory. The bar code tags are printed out automatically e.g. as the jumbo reel is ready at the paper machine. Scanning of the label automatically opens the correct sample and test variables on the value entry form.
The roll set analysis combines profile scans, defect information and laboratory test results with the trim pattern for the jumbo reel. Thus, all applicable quality information is applied to individual rolls before the jumbo reel is cut at the winder. The roll quality is compared to customer specific quality requirements, and in case of poor quality, the system automatically downgrades the roll preventing it from being shipped. This ensures that the customer requirements are fulfilled in every delivered roll, and additionally, it gives the operator a chance to re-trim in order to minimize the losses.
