A method for fitting a tubular roll shell ( 2 ) of a roll ( 1 ) in a paper or board machine. In the method, the roll shell ( 2 ) is supported on a stationary roll shaft ( 3 ) by means of hydrostatic slide bearing elements ( 4 a , 4 b ; 4 a', 4 b'; 5 a , 5 b ; 5 a', 5 b'), acting on the roll shell ( 2 ) in radially opposite directions, at least in the direction of a plane co-directional with a first plane or a plane parallel to a primary loading (F) and in a plane substantially lateral to a plane co-directional with the primary loading (F). The slide bearing elements ( 4 a , 4 b , 4 a', 4 b', 5 a , 5 b , 5 a', 5 b') are loaded hydraulically by means of a pressure fluid. The lateral bearing elements ( 4 a , 4 b ; 4 a', 4 b') acting in radially opposite directions have a hydrostatic pressure thereof adjusted by means of a regulator ( 20 ) having feedback connection with the main bearing elements ( 5 a , 5 b , 5 a', 5 b') acting in the direction of a plane co-directional with the primary loading (F) to comply at a predetermined ratio with the maximum hydrostatic pressure of the main bearing elements ( 5 a , 5 b , 5 a', 5 b') acting on the roll shell ( 2 ). The invention relates further to an apparatus for applying the method. |
