The structure is preferably comprised of a combination of metallic material and composite material.

Abstract: In a paper or board machine drying line after the wire section, during dewatering a web's (W) width is affected in a direction crosswise to the web's traveling direction. Starting from an edge, at least one device (20A, 20B) brings about a force effect of a desired magnitude which is directed all the way to a desired arbitrary crosswise web position in order to modify web characteristics. A device in a paper or board machine line after the wire section has means for processing the web and for dewatering. The paper or board machine line after the wire section further has at least one device (20A; 20B) for directing a force effect at a desired partial area (WS) of the web (W) in the cross machine direction in order to modify the web's characteristics profile in the cross machine direction.

Abstract: A processing device and method applying the same for processing a coated or uncoated fibrous web is provided. The device comprises a belt configured to extend around a guiding element, at least one counter-element being disposed outside said belt to provide a contact area with the belt, such that the belt and the counter-element establish therebetween a web processing zone for passing a web to be processed therethrough. The processing zone length is defined by the disposition of the belt's guiding element and/or by the configuration of the counter-elements. The contact pressure applied to a web in the processing zone is within the range of between about 0.01 MPa and about 200 MPa.

Abstract: A beam structure for a web forming machine is arranged to be supported by its end components (10) on the web forming machine. The beam structure includes a casing structure (15) of a thin-sheet material, inside which a stiffener structure (30) is arranged. In addition, the casing structure (15) and the stiffener structure (30) are secured to each other to create a load-bearing beam structure.

Abstract: 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.
