  • Patent number: 8133355
    Abstract: The invention relates to a method in the wet end of a web forming process. In the method, at least one electrode pair (102, 103) is placed in the wet end. The electrode pair (102, 103) is supplied with a current/voltage from a power source (100), so that an electric field is set up between the electrode pair (102, 103), causing the material particles in the pulp suspension in the wet end to be electrically charged in a desired manner and to move in a desired manner in the pulp suspension in the wet end. The current/voltage of the power source (100) is controlled by means of a measuring and control unit (101) so as to cause the material particles in the pulp suspension to be electrically charged and to move in a desired manner, thus allowing the retention, formation and orientation of the material particles in the pulp suspension to be substantially improved.
