Zellstoff Pöls AG - Paper machine

Project description

The Heinzel Group is building a second large paper machine for the production of bleached kraft paper at the Zellstoff Pöls AG site in Austria. So-called MG papers are used for flexible packaging and show superior market growth. With the new machine, a total of 200,000 tons of MG papers can be produced annually at the Pöls site.
With a diameter of 7.3 meters and a total weight of around 200 tons, the drying cylinder is the largest welded high-precision drying cylinder in the world.

Location: Styria, Austria

Commissioned by: Zellstoff Pöls AG

Performance period: 2018 – 2019

GEODATA services:

The rolls of a paper machine require a high-precision alignment, especially for parallelism. In order to meet these requirements, a high-precision network for SMR adapters over an area of 130 m x 25 m and a total height of approx. 20 m was created before the beginning of the assembly work. This network serves as the basis for all stakeout, setup and control surveying activities throughout the entire construction period. This procedure made it possible to precisely align the steel structure in advance, which made the alignment and assembly of the rollers much easier and saved a significant amount of time.

Another challenge was the installation of the Yankee cylinder. The lower half was levelled exactly in front of the hall to facilitate assembly of the upper half. After assembling the two halves, the entire Yankee cylinder was exactly aligned by using the prepared axle markings and removed.
