Myllykoski Paper is forging ahead with a rebuild PM 4 at its Myllykoski plant in Anjalankoski, Finland. Siemens is expected to overhaul the PM's electric drive and Metso Paper is expected to upgrade the unit's existing coater and replace the two coating heads. The project will improve the quality of PM and increase the unit's lightweight and medium weight coated paper capacity from 160,000 tonnes/yr to 180,000 tonnes/yr.
