Abstract

A method for fitting a tubular roll shell () of a roll () in a paper or board machine. In the method, the roll shell () is supported on a stationary roll shaft () by means of hydrostatic slide bearing elements ('), acting on the roll shell () 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 (′) are loaded hydraulically by means of a pressure fluid. The lateral bearing elements (′) acting in radially opposite directions have a hydrostatic pressure thereof adjusted by means of a regulator () having feedback connection with the main bearing elements (′) 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 (′) acting on the roll shell (). The invention relates further to an apparatus for applying the method.
