Method and apparatus for reducing moisture differentials of a moving web (1), for instance, a paper web, containing longitudinal wet streaks, by applying high-frequency electromagnetic energy to bar-formed electrodes (2), which are located close to the surface of the web (1). In accordance with the invention, the longitudinal axes of the electrodes (2) are aligned approximately parallel to the machine direction of the web (1) and the electrodes (2) are located over each wet streak of the web (1). The apparatus in accordance with the invention comprises a beam (3) extending in the cross direction essentially over the web (1), with each electrode fitted to the beam so as to align the longitudinal axis of the electrode in the home position approximately parallel to the machine direction of the web (1) and provided with a means of transferring each electrode in the aforementioned cross direction onto an assigned wet streak in the web (1). The invention provides an economical and effective solution for reducing moisture differentials in the web (1). |
