Latest Patents

Känsäkoski's latest patents include a "Method and apparatus for measuring coating" and a "Method and apparatus for measuring properties of paper." The first invention relates to a method and an apparatus for measuring a coating from paper or board. The measurement is carried out by one detector at different times or by two detectors simultaneously. Infrared radiation directed at the coating and radiation emerging from the coating are chopped synchronously in blocks. A wavelength band sensitive and insensitive to absorption is bandpass filtered and measured in both the MIR and NIR regions. The absorption strength is measured in a digital signal processing block by comparing the radiation sensitive to absorption to the radiation insensitive to absorption. The amount of each coating component is determined in the digital signal processing block based on the absorption strength. The second invention focuses on measuring the properties of paper from a moving paper web in a paper machine. An infrared beam is directed to the paper web, and the beam, passed through or reflected from the paper web, is split into wavelength components with a spectrograph. Signals of the different wavelength components are measured, and the properties of paper are determined based on these signals.
