Start-up with Valmet paper machine clothing

Valmet supplied paper machine rebuild for Stora Enso's PM3 in Varkaus started up successfully. The mill feels that a single point of responsibility is beneficial, as there are fewer players and thus fewer overlaps in the start-ups.

Improved efficiency for paper and board making with dryer fabric for single felted groups

The demands placed on paper and board machine clothing are high, as the fabrics have to support the smooth operation of the entire production line. Dryer fabrics also need to withstand high temperatures, high fabric wear risk caused by mechanical seals and rolls, as well as high-pressure cleaning up to 600 bars.
