    摘要： The invention relates to a roll for a paper or board machine comprising axle journals on whose support the roll is arranged to revolve, end flanges with which the axle journals are connected, and a mantle which is connected with the end flanges. The mantle is provided with a number of openings extending through the mantle and/or recesses formed into the outer surface of the mantle, which openings and/or recesses form a regular pattern. Solid connecting portions in the outer surface of the mantle around said openings and/or recesses are opened so that, from each opening and/or recess, there is a connection, provided in the form of a groove or an additional recess extending into the outer surface of the roll mantle, with at least each of the openings and/or recesses adjacent to it.

    摘要： An arrangement of equipment in connection with a variable crown roll provided with loading shoes to prevent foaming of fluid. The arrangement includes a separate guide and a face that guides the fluid in order to guide the fluid smoothly away from the inner face of the roll mantle of the roll and into a collecting trough.

    摘要： Method in a variable-crown roll in which hydraulic loading elements or a series of hydraulic loading elements are used. Such series of elements acts along a plane of a nip that can be formed between the variable-crown roll and a counter-roll thereof, with such elements or series being situated between a central axle of the roll and a cylindrical mantle which is rotatable about the central axle through radial bearings. The central axle is supported by axle journals thereof on deflection bearings. In the method, the central axle is pivoted about the deflection bearings thereof over an angle which is within a range of about 30.degree. to 180.degree.. By the effect of such pivoting, the variable-crown roll and the mantle thereof are shifted away from the nip, so that the nip is opened. This shifting is produced by the axis of pivoting of the deflection bearings being situated by a certain eccentricity distance further away from a nip line of the closed nip, than the axis of rotation of the roll mantle.

    摘要翻译： 使用液压装载元件或一系列液压装载元件的可变冠辊中的方法。 这样的一系列元件沿着可以形成在可变顶辊和其相对辊之间的辊隙的平面上起作用，这些元件或系列位于辊的中心轴之间，并且可以围绕 中心轴通过径向轴承。 中心轴由转轴轴承的轴颈支撑。 在该方法中，中心轴围绕其偏转轴承以约30°至180°的范围内的角度枢转。 通过这种枢转的作用，可变冠辊及其外套从辊隙移开，从而打开辊隙。 该偏移由偏转轴承的枢转轴线与离开辊套的旋转轴线相距一定偏心距离进一步远离密闭压区的压区而产生。

    摘要： A gradient calender including two calender rolls arranged to form a calendering nip, at least one of the rolls being a hard-faced calender roll which is heatable to a high temperature whereby a web is passed through the calendering nip for hot calendering the web. At least one of the calender rolls is arranged to be loaded toward the calendering nip by a respective variable-crown support roll so that an auxiliary nip between the support roll and the respective calender roll and the calendering nip are in a common nip plane. Deflection of the calendering nip and the calender rolls is substantially prevented by the effect of the load produced by hydraulic loading devices arranged in the support roll.
