<p>The invention relates to a method for compensating variations in nip loading caused by shape errors in a roll shell in a calender, in which method the web (9) being calendered is threaded through a nip (N) formed by two rotating rolls (2, 3) and the and loading of the nip is adjusted using loading devices (11). In the invention, the shape profile of at least one of the rolls (3) of the nip is defined and the loading devices (11) are controlled on the basis of the shape profile and the angle of rotation of the (3), in order to compensate the nip-loading variations caused by shape errors.</p> |
