ABSTRACT:
The invention relates to a method for adjusting the properties of the polymer coating (2) of a roll or a belt (3), whereby the roll or the belt is used for calendering a fibrous web (4) in a roll nip (N), which is formed between the roll or the belt and its backing roll (5), whereby the roll or the belt has a polymer coating comprising fibrous material (1). In the method, the thermal elongation coefficient and/or thermal conductivity of the polymer coating (2) are adjusted by directing the fibre direction of the fibrous material (1).
