Sep 26, 2005. /Lesprom Network/. In the scope of the rebuild of PM 4 at Langerbrugge, Belgium, two polyurethane suction press roll covers – Aqualis - were ordered from Voith Paper Rolls. The custom-made surface design of Voith Paper’s Aqualis suction press roll cover decisively contributes to optimized dewatering of the paper sheet and the increase in dryness content. Due to the innovative cover construction, AST bonding and the use of high-tech materials, this cover generation has proven to be first choice in modern, fast paper machines. With more than 650 covers in use today, Aqualis is the market leading standard solution for suction press rolls. The world’s largest paper machine with a wire width of more then 11 meters and a design speed of 2000 m/min was started up after the successful rebuild in March 2005. Voith Paper is a division of the Voith Group and one of the leading partners to the paper industry. More than one third of the world's paper production is produced on Voith Paper machines.
