Resource saving metal belt calendering giving better paper surface awarded the 29th Marcus Wallenberg Prize
During a ceremony at the Grand Hôtel in Stockholm on 1 October, the Swedish King, His Majesty Carl XVI Gustaf awarded the Marcus Wallenberg Prize 2012 to Mr. Mika Viljanmaa for his ground-breaking development of metal belt calendering technology resulting in better paper print surfaces with less fibre materials and higher production efficiency.Calendering is done to improve the paper surface and thus print quality. Compared to conventional calendering, the metal belt calendering technology enables manufacturing of paper and board with better surface smoothness at a desired level of
