The Valmet-supplied containerboard base paper machine at Propapier PM2 GmbH in Eisenhüttenstadt, Germany, set a 24-hour world speed record of 1,704 m/min on April 24, 2014. During the record run, the 10.85 m-wide PM2 produced corrugating medium at basis weight of 70 gsm with a total efficiency of 96%. The Propapier PM2 was originally started up in March 2010.
This was already the fourth 24-hour world speed record set by Propapier PM2. On November 25, 2010, the machine set a record of 1,620 m/min at a basis weight of 90 gsm becoming the world’s first containerboard machine to exceed the 1,600 m/min speed level. The next world record followed in April, 2011 when the machine reached the speed of 1,650 m/min at a basis weight of 80 gsm. On February 23, 2012, the machine set yet another 24-hour world speed record of 1,675 m/min at a basis weight of 80 gsm, thus breaking the 100 km/h milestone.
The PM2 is an OptiConcept paper machine featuring Valmet’s modern paper making technology from the stock preparation plant all the way through the paper machine. The design speed of the machine is 1,900 m/min.
