<p>A method for changing the natural frequency of a nip roll construction in a paper or board machine. In the method, the bearing elasticity of a hydrostatic bearing element (10, 20, 30, 40) of at least one roll (1) in the nip roll construction is changed, in which connection the natural frequency of the roll (1) is also changed. The device that carries out the method comprises a pressure medium accumulator (39), which has been connected to the pressure side of a loading element (13, 23, 33) of at least one hydrostatic bearing element (10, 20, 30).</p> |
