Abstract
The invention relates to a method for controlling the transverse fibre orientation profile of a paper web W in a paper machine. The water is removed from the paper web W in that it is pressed between two forming wires 11, 21, by utilising the drainage and/or forming strips 14, 24. In the method the transverse deflection of the web W by the drainage and/or forming strip or strips is controlled, thereby influencing the transverse retention profile of the web W. The retention profile is adjusted so that the control system 100 of the paper manufacturing process controls the profile on the discharge opening A of the head box 30 also at the edge areas, so that the width is essentially uniform, so that no essentially deviant transverse flow rate will be created in the fibre orientation profile. <IMAGE>
