Latest Patents
One of Vikman's latest patents is a method and apparatus for producing mechanical fibers. The purpose of this invention is to provide a method and an apparatus for producing thermomechanical fibers using less energy per ton than has previously been required for similar types of production. This invention combines at least two refiners, allowing a mixture of chips, water, and steam to be fed into a first refiner. In this process, the chips are broken up, and the mass flow from the first refiner is then fed into the second refiner for breaking the fibers to the final freeness level. The mass flow of steam and fibers is propelled forward in the first refiner by the rotational energy of the refiner rotor, ensuring that essentially no flowback of steam occurs. Importantly, the mass flow exiting the first refiner is completely fed to the second refiner, with no steam extracted from the mass flow before reaching the second refiner.
Another significant patent by Vikman is a method for two-side coating of a thin printing paper web containing mechanical pulp or recycled fiber. This method involves coating the first side of a web in a first coating station, followed by partial drying in a first dryer unit. The second side of the web is then coated after the first side has dried, in a second coating station, with the coating applied to the second side also undergoing partial drying in a second dryer unit. Both coatings are formed by applying the required amount of coating mix onto the perimeter of respective soft film-coating rolls and subsequently transferring the coat film to the web in a nip formed between a respective backing roll and the respective soft film-coating roll.
