    摘要: A roll comprises a shaft (12), which consists of a cylindrical middle part (12c) and an end part (12a, 12b) at each end of the middle part (12c) by means of which the shaft (12) is rotatably bearing-mounted in end bearings (13a, 13b), and a shell (11) fitted on top of the middle part (12c) of the shaft (12) which shell rotates along the shaft (12). The middle part (12c) of the shaft (12) comprises at least one pressure volume (61) to be pressurised with pressure medium, whereby the part of the outer surface of the middle part (12c) being outside the pressure volume (61) in the direction of the radius of the shaft (12) determines a peripherical joint surface (60). When said at least one pressure volume (61) is pressurised, the middle part (12c) expands from the area of the joint surface (60) in the direction of the radius of the shaft (12) to form a non-rotatable joint between the shaft (12) and the shell (11).

    摘要: The invention relates to a method for producing a fiber web (W), in which method the fiber web (W) is calendered in at least one calendering nip (NA; NB) of at least one calender (20A; 20B) and reeled up in a reel-up (40). The fiber web (W) is cooled by cooling means (10A; 10B) before calendering to temperatures of not higher than 40 °C, preferably to temperature in the range of 10 - 30 °C. The invention also relates to a production line for producing fiber webs (W), which comprises at least one calender (20A; 20B) with at least one calendering nip (NA; NB) and a reel-up (40) after the calender (20A; 20B). The production line comprises at least one cooling means (10A; 10B) before the at least one calender (20A; 20B) for cooling the fiber web to temperatures of not higher than 40 °C, preferably to temperature in the range of 10-30 °C.

    摘要: The invention relates to a method for modernizing a multiroll calender, which multiroll calender is for calendering a fiber web, particularly a paper or board web (W), which multiroll calender comprises at least one stack of calender rolls (10, 20), each stack comprising at least two calender rolls (11, 12, 13, 14, 21, 22, 23, 24) and at least one of the calender rolls is a smooth-surfaced press-roll (12, 22). In an existing multiroll calender at least one smooth-surfaced press roll (12, 22) is replaced by an ultra thermo roll that is a thermo roll diameter of which is substantially the same or less than the diameter of the thermo roll to be replaced, surface temperature of the ultra thermo roll when heated is at least110 °C, at least 10 °C higher surface temperature than surface temperature of rolls of prior art with same heating fluid temperature and having flow channels arranged in such way that the vibration excitation is minimized, advantageously arranged to form a spiral shaped geometry in the mantle.
