摘要： A roll has a continuous tubular roll shell (11) of a composite material and axle journals (12) rotating together with the roll shell and joined to each end of the roll shell. The axle journals are supported on a supporting element (13) surrounding the axle journal (12) by at least two bearing elements (14, 15) located at a distance from each other in the axial direction (X—X) of the roll, which supporting element (13) for its part is supported on the machine frame structures (R). The first bearing element (14, 15) is supported on the supporting element (13) through a bending mechanism (20, 21), which is used for applying to the first bearing element (14, 15) a force affecting in a radial direction in order to deflect the first bearing element (14, 15) in relation to the central axis (X—X) of the unbent roll, whereby the axle journal (12) will bend in relation to a pivot point which is formed at the second bearing element (14, 15) and a bending moment is applied to the roll shell (11).

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 roll for a paper or board machine is produced by forming a tubular roll blank by bending out of a planar sheet or by means of centrifugal casting. The roll blank is first coated with a material having a modulus of elasticity and a density lower than those of steel and the coated roll blank is turned on a lathe to a desired shape and to a desired surface quality.

摘要： An extended-nip press device comprises a press shoe extending in a cross-machine direction and a support for supporting the press shoe. Between the shoe and the support are arranged a plurality of loading cylinders for moving the shoe toward a backing member such as a counter roll to apply pressure to a fibrous web passing through the nip between the shoe and counter roll. Each loading cylinder comprises a first cylinder member fixed on the shoe and a second cylinder member fixed on the support, and a connecting member that slidably engages both cylinder members. The connecting member can slide relative to the first cylinder member with a first stroke length L1 that is smaller than the stroke length L2 between the connecting member and the second cylinder member. Accordingly, the connecting member can remain essentially aligned along the lengthening direction of the loading cylinder.

摘要： A shoe press for applying pressure to a moving web of paper or the like includes a press shoe extending along a full width of the web being carried through a nip defined between the shoe and a backing member, a support for the shoe, and a plurality of articulated hydraulic loading cylinders arranged between the support and the shoe for urging the shoe toward the backing member to apply pressure to the web. Each loading cylinder includes a single piston and first and second cylinders attached to the shoe and to the support, respectively. The opposite end portions of the piston are slidably received within the cylinders so as to define working chambers in the cylinders which are pressurizable by hydraulic fluid for urging the two cylinders away from each other. The piston engages the cylinders at seals which enable the piston to pivot with respect to both cylinders about axes parallel to and perpendicular to the machine direction so as to enable the loading cylinders to accommodate deformations and thermal expansion of the shoe in the cross-machine direction and to allow the shoe to pivot about an axis perpendicular to the machine direction.

摘要： The object of the invention is a method for synchronizing image data obtained from process monitoring cameras. By utilizing synchronization, one and the same area in a paper web can be sought as it passed the different camera positions. Since the speed are high and the webs somewhat stretching, synchronization does not often directly result in the same area being shown in the different camera positions. To facilitate search, a selection area corresponding to the limited number of sequential images in the environment of the point of synchronization of each camera position is visualized for the operator, inside which area the corresponding area in the web can be found with certainty.

摘要： The invention relates to a method for monitoring a process. The image information received from cameras monitoring various positions of the process is stored in digital form and various cameras positions are alternately selected for a display and analysis on the screen of a computer. The screen is also used for displaying an image variation graph representing the image variation data of images preceding and following the image to be analyzed. The system includes selector elements (5) for selecting a camera position representing the highest-level image variation for an automated display.

摘要： Suction box in a paper machine including a vacuum chamber, a deck or a number of substantially U-section holders open toward a wire and ribs arranged in the deck or the holders so that they can be loaded against the wire. At least in a running situation, the deck of the suction box is curved or the ribs are arranged to provide a curve run of the wire so that the wire tension of the curved run over the deck or ribs serves to lower a normal force which is produced by the vacuum present in the suction box and which is effective between the wire and the deck or ribs.
