Description: New specialty paper machine of Koehler Paper convinces with latest technology and digital solutions from Voith. The new production line for machine-glazed specialty papers for Papierfabrik August Koehler SE went into operation at the end of October 2019. With a volume of 300 million euro, this is the largest single investment in Koehler’s company history. Production line 8 was installed at the company’s Kehl site in a project time of only two and a half years and consists of a BlueLine stock preparation unit, wet end process, XcelLine paper machine, offline coating machine and VariPlus winder. The paper manufacturer further relies on the maintenance solution OnCare.Asset and the condition monitoring system OnCare.Health from Voith.

Details: Designed for around 100,000 tons per year, production line 8 produces an extensive portfolio of standard papers and papers with functional surfaces for flexible packaging. The 150-meter-long machine has a wire width of 5,000 mm and design speed of 1,500 m/min. Its centrepiece is the world’s biggest Yankee cylinder with a diameter of more than 7,300 mm. It gives the paper its unique smoothness, which is very important for further processing. The innovative Nipcorect Fullflex roll is used as a press roll at the Yankee cylinder and allows ideal line load distribution over the whole width. The multi-layer coating for differentiating premium paper qualities is realized with the offline coating machine SM 8, which is fitted with the DynaLayer, the latest curtain coater technology from Voith, and non-contacting, gentle drying with high thermal efficiency thanks to MCB- Dryers. The final smoothing of the specialty papers is done using an innovative calendering concept.
