NOVEMBER 9--Honeywell Process Solutions, part of Honeywell's Automation and Control Solutions group (www.honeywell.com), has received an order to provide a quality-control and web defect-detection system to Stora Enso's paper mill in Kvarnsveden, Sweden. The systems will improve production efficiency and paper quality at the mill.
Honeywell will supply and install three Da Vinci quality-control systems and four Web Imaging Systems (WISs) for the mill's new production line. The production line is scheduled for startup in the autumn of 2005 and will be one of the largest in the world, producing high-quality magazine paper at a speed of 2 km/min.
The Da Vinci system measures basis weight, caliper, moisture, ash, gloss, and color at the paper machine and at the two supercalenders. Exceptional scanning speed and cross-directional profile resolution of the Honeywell sensors ensure excellent quality-control results despite the high production speed and the 10.4-m web width.
The Honeywell WIS system, powered by Cognex machine-vision technology, detects and classifies even the slightest defects in the paper web. The system locates the defects and automatically stops the winder at a selected defect, thus enabling it to be quickly eliminated from the web. Efficient web defect management will minimize waste, reduce the number of web breaks and improve paper quality for end-customers.
Kvarnsveden Mill is part of Stora Enso's Paper product area. Today the mill has an annual production capacity of approximately 700,000 tons of newsprint, improved newsprint, and uncoated magazine paper. With the new production line, the total capacity will exceed 1 million tons per year.
