    摘要： An applicator device (1) applies surface size to at least one side of a web (W). A pressure effect is applied to the web (W) by subjecting the web (W) to an underpressure and/or to an overpressure such that surface size is forced to penetrate into the pores of the web. Most advantageously, an underpressure is created that sucks applied surface size from the surface of the web (W) into the pores in the inner layers. Surface size is applied to a web first side (W1) and a vacuum effect is applied to the web's opposite side (W2) to cause air to flow through the web (W) such that surface size moves from the first side (W1) in the direction of the second side (W2) into the web (W). Correspondingly, both sides of the web (W) can be treated in successive stages.

    摘要翻译： 施加器装置（1）将表面尺寸施加到幅材（W）的至少一侧。 通过使幅材（W）承受负压和/或超压使得表面尺寸被迫渗透到幅材的孔中，对幅材（W）施加压力效应。 最有利的是，产生了将从表面（W）的表面吸收的表面尺寸吸收到内层中的孔中的负压。 将表面尺寸施加到幅材第一侧（W1），并且将真空效应施加到幅材的相对侧（W2），以使空气流过幅材（W），使得表面尺寸从第一侧（W1）移动到 第二侧（W2）到卷筒纸（W）中的方向。 相应地，纤维网（W）的两侧可以连续处理。

    摘要： A multi-roll calender, supercalender, soft calender or equivalent has at least one nip (YN, PN1, KN, PN2, AN) profiling a fibrous web (W) which is being calendered. A shoe roll (1, 4, 6, 10) constitutes at least one of the calender rolls which define the nip. A shell (11, 41, 61, 101) of the shoe roll is of a composite material, and the shoe roll is provided with internal shell-loading shoes (12, 42, 43, 62, 63, 103) for profiling the shell, the nip and/or the fibrous web.

    摘要： The invention relates to a slide shoe assembly for a roll (1) in a paper/board machine or a finishing machine, said roll (1) comprising a stationary axle (4), around which is rotatably mounted a cylindrical roll shell (2), a clearance (5) formed between the axle (4) and an inner surface (3) oF the roll shell (2) being fitted with loading elements (11) operated by a pressurized hydraulic fluid and provided with slide shoes (10, 110) which are loadable against the inner surface (3) of the roll shell (2) for controlling the distribution of a nip pressure in a nip (N) established with a counter roll (9). According to the invention, the loading element is equipped with means capable of eliminating or compensating for a nip-load induced deflection of the roll shell and/or a deflection of the slide shoe caused by the pressure of a hydraulic medium, thereby eliminating the harmful effects caused by said deflections on an oil film between the loading shoe and a cylindrical surface supported thereby.

    摘要： A method for fitting a tubular roll shell (2) of a roll (1) in a paper or board machine. In the method, the roll shell (2) is supported on a stationary roll shaft (3) by means of hydrostatic slide bearing elements (4a, 4b; 4a′, 4b′; 5a, 5b; 5a′, 5b′), acting on the roll shell (2) in radially opposite directions, at least in the direction of a plane co-directional with a first plane or a plane parallel to a primary loading (F) and in a plane substantially lateral to a plane co-directional with the primary loading (F). The slide bearing elements (4a, 4b, 4a′, 4b′, 5a, 5b, 5a′, 5b′) are loaded hydraulically by means of a pressure fluid. The lateral bearing elements (4a, 4b; 4a′, 4b′) acting in radially opposite directions have a hydrostatic pressure thereof adjusted by means of a regulator (20) having feedback connection with the main bearing elements (5a, 5b, 5a′, 5b′) acting in the direction of a plane co-directional with the primary loading (F) to comply at a predetermined ratio with the maximum hydrostatic pressure of the main bearing elements (5a, 5b, 5a′, 5b′) acting on the roll shell (2). The invention relates further to an apparatus for applying the method.
