Valmet to Supply New Sizing Technology for Papierfabrik Niederauer Mühle in Germany

An OptiSizer is part of Valmet's delivery to Niederauer Mühle's Kreuzau paper mill in Germany.

June 24, 2014 - Valmet said that it will supply Papierfabrik Niederauer Mühle GmbH with a sizer and auxiliaries for its PM3 containerboard machine located in the company's Kreuzau mill in Germany. The target of the project is to improve the strength properties of the white top liner grades. This high quality paper is used for instance as printed cover layer for cardboards and as headliner.

The value of the order will not be disclosed.

The sizer is scheduled to start up during the first quarter of 2015, Valmet noted.

In addition to the new sizer, Valmet's delivery will include a calender rebuild, an air dryer, starch preparation and starch supply systems as well as ropeless tail threading equipment.

"The new sizer will combine the best features of both spray application and film application, and improve the strength properties of the white top liner grades," said Ilkka Naatti, Product Manager of coaters and sizers in Valmet. "The main advantages of the back side spray application technology compared to conventional starch application method are drying energy reduction, fast and accurate starch amount control as well as elimination of wearing parts. The top side film application ensures excellent properties of the white top liner surface."

"Niederauer Mühle will also be the first paper mill in the Central Europe to benefit from the advantages of safe, reliable and fully ropeless tail threading technology in the size press area. After the rebuild the tail threading process of PM3 will be totally ropeless for all machine parts," Naatti added.

Niederauer Mühle specializes in white corrugated medium paper of which basis weight ranges from 120 - 200 g/m2. Currently, the company's production volume is more than 300,000 tons of paper per year and it employs 155 people.
