Abstract (en)

[origin: EP2202356A1] The invention is a new system for adjusting and controlling at least the humidity content of paper (F) during the production cycle in paper production plants, comprising one or more devices (M) that emit microwaves at controlled frequency and are suited to dehumidify areas of the paper (F) while the paper (F) slides. The new system comprises also measuring devices (C) suited to determine the paper humidity profile (P) along a measurement section (F2) and an electronic unit (S) that receives data from said measuring devices (C) and activates/deactivates and/or modifies the power of the microwave emitting devices (Mx) that act where humidity peaks are detected.
