From September 14 to 20, Rodolfo Comerio held an open house event to unveil one of the world’s largest calenders of its kind. The most important of the various features characterizing this machine are its five gigantic rolls, each with a diameter of 870 mm and a length of 5000 mm on the table (or 8000 mm if we also consider the cylinder pins), and its installed capacity of 1400 kW .
