Abstract
Method and device for moisture profiling of fibrous material web to be dried in machines for manufacturing and/or refining of fibrous material web. Method includes subjecting fibrous material web to electromagnetic waves in the form of high-frequency waves. Device includes a fibrous material web support that supports travel of fibrous material web and a rotating cylinder. Rotating cylinder receives fibrous material web from fibrous material web support, and fibrous material web support is arranged outside fibrous material web in relation to the surface of the rotating cylinder. At least one electromagnetic wave transmitter is also included. Rotating cylinder conveys fibrous material web past the at least one electromagnetic wave transmitter, electromagnetic wave transmitter produces electromagnetic waves laterally to material fibrous web, and electromagnetic waves balances out moisture variances laterally to fibrous material web by drying moister areas of fibrous material web more intensely than dried areas of fibrous material web.
