Kehl PM 8 – A technical masterpiece
Comprising BlueLine stock preparation, a wet end process, XcelLine paper machine, offline coating machine, and VariPlus winder from Voith, production line 8 is one of the most powerful specialty paper machines in the world.
"Optimized stock preparation is important to guarantee the high quality requirements of specialty paper. Our tried-and-tested BlueLine product portfolio is being used on paper machine 8. The customized process concept and high-performance components make a significant contribution to the efficient operation of the mill."
Axel Gommel, Global Product Manager at Voith Paper
Miltenberg TM 7 – Complete production line from Voith
Thanks to innovative product solutions and a coherent full-line supplier concept, the TM 7 from Fripa has been efficiently and reliably producing hygiene papers of the highest quality since 2014. Voith supplied the complete production line – stock preparation, approach flow system, tissue machine including auxiliaries, electrification, automation and engineering of the entire plant.
A perfectly aligned process with market-leading components
In combination with sophisticated automation solutions, the customized process concepts and highly efficient components from the BlueLine product range contribute significantly to the cost-effective operation of the plant. Voith covers the complete process, from stock preparation through approach flow system to fiber recovery and broke handling. An overview:
Approach flow system
The IntegraGuard screen is used in the first stage of the approach flow system and has been designed to fulfill highest requirements without additional pulsation damper. In the subsequent second and possibly third stage, the aim is to concentrate and continually remove the rejects to achieve low reject rates in virgin fibers. This is achieved with the IntegraScreen in combination with MultiFoil rotors and C-bar screen baskets.
The InduraClean concept has a modular structure that allows the cleaners to be easily adapted to the customer’s individual requirements and production targets.
