STOCKHOLM, March 21, 2011 (Press Release) -Just at the end of February 2011 SCA Hygiene Products has started up with Toscotec the major rebuild of the tissue machine PM 3 in Mannheim (Germany).

The project target was mainly to increase the machine speed up to 2000 mpm maintaining the same trim width and to improve paper quality, making softer products, as well as the runnability and maintenance. The stock preparation system and the machine was upgraded in order to have possibility to manage products with different furnish.
