ANDRITZ paper technology sets new standards in containerboard production


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 1,450 m/min at a basis weight ranging from 70 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.

Only ten weeks were scheduled for the rebuild work. ANDRITZ successfully mastered this challenge and at the same time enabled the continued operation of the PM11 during the rebuild work. The PM10 produced saleable containerboard from the very first reel.

Jan Reibert, Production Manager PM10 of Laakirchen Papier, explains: “As of today, the PM10 produces premium quality lightweight containerboard at record speeds. And we still have an ace up our sleeve: there is still potential for further increases in performance. The next step is for ANDRITZ to upgrade the ropeless tail threading system in the double-tier part of the after-dryer section to reduce machine downtime and threading times 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. In addition to the PM10 rebuild at Laakirchen, ANDRITZ also supplied and successfully started up the largest new MG paper machines in Europe (PM3 and PM2) at Zellstoff Pöls, Austria
