Latest Patents
One of his 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. The method allows for the coating color to be dried, resulting in a coated web. The innovation involves using 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 applied at a speed of at least 1450 m/min, preferably over 1600 m/min. This steep particle size distribution enables the coating color to solidify at much lower dry substance compared to conventional colors, allowing for high-speed coating without runnability and quality issues.
Another significant patent by Leskelä is a procedure for adding a filler into a pulp based on cellulose fibers. This invention describes a method where the pulp is fluidized, and the filler is added during this state. The pulp is stirred while the filler, preferably calcium hydroxide, is introduced. The process also involves precipitating calcium carbonate with carbon dioxide, enhancing the efficiency of the pulp processing.
