Poor runnability at Stora Enso Anjala PM2 (bookpaper) drying section created problems in higher machine speeds. In the double felted section sheet fluttering caused wrinkles. In single felted section it was impossible to increase the speed, because the web did not release nicely from contact and followed the upper cylinder surface.
The PM2 drying section runnability was optimized in two steps. In 2009, runnability problems of the double felted section were eliminated with machine geometry modification and stabilizing technology tailored for the area. In the second step, in 2010, runnability of the single felted section was optimized with the EV EasyOne technology / high vacuum stabilizing technology.
”The problems because of poor runnability are eliminated after the web stabilizing projects in single and double felted sections. We have now more stable sheet run, and the drying section runnability enables also higher speed.” (Mr. Antti Outinen, Production Manager, Stora Enso Anjala PM2)
