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
