he world’s most modern board machine is located in Gruvön, Sweden. The entire machine, from headbox to winder, was built by Voith for BillerudKorsnäs. With its high-end components, the BM 7 doesn’t just define the latest state-of-the-art installation. Thanks to the large degree of component interconnectedness and extensive monitoring of all process data, it is actually pointing the way to the digital future of the paper industry. Patric Romes is not inclined to exaggerate. But when he’s talking about the board machine that Voith built for BillerudKorsnäs in Sweden, even the voice of the seasoned senior project manager resonates with respect. “To my knowledge, such a fully equipped system for high-quality board has never been realized anywhere else in Europe in recent years. It is an outstanding achievement that is setting benchmarks,” says the 58-year-old. The BM 7 is an end-to-end system and the world’s most modern board machine. Romes and the Voith team installed the machine at the company’s mill at Lake Vänern in Gruvön, Sweden. It went into operation in June 2019.The standards it now has to meet are exacting. The BM 7 produces four different board grades with a total annual volume of 550,000 metric tons from virgin fibers from sustainably managed forests. To achieve this capacity, the machine works with a web width of 8,800 mm at the headbox and a design speed of 1,200 m/min.
