The PM10 at Laakirchen Papier AG, part of the Heinzel Group, Austria, that was rebuilt by ANDRITZ has become the world’s fastest converted containerboard production machine with speeds of up to 1,420 m/min at a basis weight ranging from 80 to 140 g/m².
Over the last few years, ANDRITZ converted the PM10 from production of SC paper to a fluting and testliner machine. The scope of supply comprised the stock preparation section, a comprehensive rebuild of the paper machine, and the complete automation.
The time scheduled for the rebuild work was twelve weeks only. ANDRITZ successfully coped with this challenge at the same time allowing PM11 to continue running alongside the rebuild work. PM10 produced saleable containerboard from the very first reel on.
Jan Reibert, Production Manager PM10 of Laakirchen Papier, explains: “Per today, PM10 produces lightweight containerboard here in Laakirchen at record speeds. And we have an ace up in our sleeve: there is still potential for further increases in performance. The next step is the upgrade by ANDRITZ of the ropeless tail threading system in the double-tier part of the after-dryer section to reduce threading time when compared to the market standard.”
The international Heinzel Group, the largest independent, non-integrated containerboard producer in Europe, and ANDRITZ have a long and successful business relationship. Apart from the conversion of the PM10 at Laakirchen, ANDRITZ has delivered and successfully started up Europe’slargest new MG paper machines (PM3 and PM2) at Zellstoff Pöls, Austria.
