摘要： A fiber web machine roll (1 ) for processing a fiber web comprises a body (2) having a first end (2a) and a second end (2b); at least one shaft end (3a, 3b), fastened to an end of the body and comprising at least one first flow channel (4a, 4b) for conducting a heat-transfer agent in and/or out; and a shell layer around the body (2) for transferring heat from the heat- transfer agent to the fiber web or from the fiber web to the heat-transfer agent during operation. A tube-like metal shell (5) having a wall thickness of about 1 to 20 mm is arranged as a shell layer around the body (2) of the roll (1 ) so that a peripheral flow chamber (6) for the heat-transfer agent, having a height of about 1 to 2 mm in the radial direction of the roll (1 ), is formed between the body (2) and the metal shell (5), the flow chamber (6) having a flow connection to said at least one first flow channel (4a, 4b). For the roll maintenance of the fiber web machine roll (1 ), a metal shell (5) forming the shell layer can be replaced by another metal shell (5) having the same characteristics or having different characteristics. The fiber web machine roll can be implemented by modernizing old rolls to become in accordance with the invention.
