Abstract
Andritz AG (Austria Graz) had manufactured and sold paper machines under license from Escher Wyss until 1995. From 1996 Andritz started to focus on tissue paper machines and from 2000 made joint research projects in cooperation with Voith. Since 1996, Andritz installed more than forty high speed tissue paper machines mainly in Europe, North America and China. In 2005 Andritz restarted board machine business. As a result, an integrated board production facility that consists of recycled fiber line and board machine were ordered in 2007 by Hebei Yongxin Paper in China and started up in April 2009. The machine type is three-ply Fourdriniers and multi-dryer cylinders. The wire width is 6,200 mm, the design speed is 1,100 m⁄min and the production capacity is 350,000 ton⁄year. This paper reports the specifications, the machine concept and the start-up of the recycled fiber line as well as board machine.
