Latest Patents
One of her latest patents is a method for coating webs. This invention relates to a technique for applying a coating color with pigments to the surface of a fibrous web, which is then dried to form a coated web. The method utilizes a coating color that contains pigments with a steep particle size distribution, ensuring that a maximum of 35% of the pigment particles are smaller than 0.5 µm. The coating color is spread on the web at a speed of at least 1450 m/min, preferably over 1600 m/min. This innovation allows for high-speed coating without compromising runnability and quality.
Another significant patent is a process for preparing a paper web. This process involves forming pulp from fibrous raw material, creating a web from the pulp, and drying it on a paper machine. The pulp is produced from a peroxide bleached mechanical wood raw material of the genus Populus, with specific pH and conductivity settings. This method improves the stability of the paper-making process and enhances water removal, leading to better quality paper.
