Improved board machine performance at Cartiere Villa Lagarina

Sep 27, 2016

The new Valmet runnability systems at the Cartiere Villa Lagarina mill have significantly reduced web breaks and the subsequent production losses, increasing the reliability of the board machine. The average production speed has increased by more than 150 m/min, and maintenance shutdown intervals have also increased.

*earlier known as HiRun

After six months of stable, satisfactory running, we are very pleased with the decision. The effects were clear right from the first week after start-up. The stable paper web and more effective tail threading have resulted in less time being wasted and, ultimately, in increased speed and productivity."
Francesco Zago, Managing Director of Villa Lagarina
