Voith has successfully completed the rebuild of the PM 11 at Heinzel Group's heinzelpaper plant in Laakirchen, enabling the XcelLine paper machine to produce up to 470,000 tons of corrugated base paper per year.
Voith supplied a complete tailor-made package of highly efficient components, including proven stabilization and drying concepts and a comprehensive engineering package. These solutions enable efficient and sustainable production of low basis weights at high speeds, thereby contributing significantly to increasing production capacity from 330,000 tons to 470,000 tons per year.
The entire paper machine fabrics, including installation, is also part of the scope of supply. Ideal conditioning of the forming wires is ensured by the Voith CleanLine Excell, which is supplied with the fabrics. With the help of the Forming OnQ-Sense, which was also supplied and installed, heinzelpaper Laakirchen can ensure a reduction in vacuum while maintaining the same dry content, thus saving energy in the long term. The installed ProTect crossbars enable press felt measurements to be carried out while the machine is running without personnel having to enter the press interior.
During the rebuild, the paper machine and two VariTop reel stands were retrofitted, numerous components were relocated, and the web guide was adapted to the new requirements. Special attention was given to optimizing the Tandem NipcoFlex press to enable stable web running without breaks. In addition, the Voith experts installed a new SpeedSizer for applying surface strength and an energy-efficient post-dryer section. The necessary control and regulation changes were implemented by installing efficient automation systems from Voith.
The heinzelpaper site combines the Laakirchen and Steyrermühl mills in Upper Austria, which are located just a few kilometers apart. As part of the Heinzel Group, heinzelpaper stands for a strong combination of tradition, innovation and sustainability in paper production.
The Voith Group is a global technology company.
