Metso Paper inaugurated the rebuilt pilot paper machine PM 2 on February 13, 2007, at the Rautpohja Paper Technology Center in Jyväskylä, Finland. The PM 2 was successfully started up after the rebuild in September 2006. The rebuild investment included a new press section, modernization of the dryer section and several other improvements throughout the whole process line. The pilot PM 2 now has a design speed of 3,000 m/min.

The rebuilt pilot paper machine features a new OptiPress closed draw press section, designed with a totally new felt change system, which eliminates the need for expensive cantilevering designs. The felts can be pulled into the press with a new-type of felt insertion equipment. Also ergonomics and safety have been raised to a new level with a cross-machine access way and other operator-friendly solutions.

Another new feature is the OptiDry Twin impingement drying unit. The system substantially reduces the number of dryer cylinders. Its drying capacity enables a noticeable speed increase. The OptiDry Twin is located in the beginning of the drying section, where it increases the dry content of the web just after the press section, so that the sheet dry content and the temperature of the paper are high at the first dryer cylinder. This prevents sticking, strengthens the web, and enables faster paper machine operation. OptiDry Twin has more than met the target of optimal draw control and is also an excellent tool for quality and runnability control.

In total, Metso Paper has 12 technology centers covering paper, board and tissue making as well as all commercial pulping processes. The Rautpohja pilot PM 2 is one of the three pilot paper machines. In addition, Metso Paper has a pilot board machine and two pilot tissue machines, as well as an extensive range of surface treatment pilot equipment for paper finishing. With these pilot facilities, any kind of raw material can be tested from fiber to print.
