Oct 27, 2004. /Lesprom Network/. Stora Enso will modify part of its newsprint machine 4 at Langerbrugge Mill in Belgium. The machine is performing efficiently and the quality of the paper is good. However, there is a problem with dust accumulating on printing plates when printing a high number of copies on certain printing machines. It has therefore been decided to modify the press section of the paper machine to ensure the highest quality in every respect. Stora Enso and Metso have agreed on the modification required, which Metso will undertake as the supplier responsible for the machine. The modification will take about five weeks and is scheduled for early 2005. About 40 000 tonnes of production will be lost during the shutdown. Langerbrugge Mill's paper machine 4, which started up in May 2003, is the world's largest newsprint machine. It utilises exclusively recovered paper as raw material and has an annual production capacity of 400 000 tonnes, producing 45 g/m² newsprint.
