The concept of the “TRIPLE STAR” paper production line pointing the way ahead with state-of-art engineering and technology was worked out in close cooperation with Gratkorn and IHI-Voith Sulzer Paper Technology. With an annual output of 470, 000 metric tons, it is the largest production line world-wide for high-quality woodfree coated paper. The paper receives the first coating on-line in the paper machine. In a separate coating line, both sides of the paper are each coated again twice. This triple coat concept sets new quality standards in terms of printability of the paper, without negatively affecting the required runnability in the printing presses. The heart of the entire investment, KNP Leykam Gratkorn PM 11, is designed for a trim width of 8.5 m and a design speed of 1, 500 m/min.
The paper machine is equipped with latest technology, such as ModuleJet Headbox, DuoFormer CFD, DuoCentri-NipcoFlex, CombiDuoRun dryer etc. With the paper of the new paper machine, very good quality parameters, such as formation, ash and fines two-sidedness, smoothness two-sidedness, MD : CD tensile ratio, etc., were also achieved at the winder.
“TRIPLE STAR” is not only the largest production plant in the world, it is also intended to have the highest productivity and produce a new quality standard in woodfree coated papers.
