摘要： An improved method for producing paper from pulp includes a plurality of subassemblies arranged in the forming or wet section of a Fourdrinier. The Fourdrinier includes a dewatering table having a plurality of blades that are static and on-the run adjustable in height and/or angle to control orientation of paper fibers in the stock to create a superior quality of paper and improved paper strength characteristics. Gravity and vacuum assisted drainage elements are equipped with on-the-run adjustable angle and height dewatering foil blades starting from a paper dryness of 0.1% and extending all the way to 5% dryness. The result of this process and machine is to improve the paper quality, save fibers and chemicals and fulfill the required paper properties.

摘要： The invention relates to a device for dewatering a fibrous web with a press zone which is formed by a mating element with a curved surface and a permeable press belt which wraps at least partially around the curved surface and has a running side and a contact side contacting a second side of the fibrous web. A permeable carrier belt arranged between the mating element and the fibrous web guides the fibrous web through the press zone. The device is configured so a fluid can flow through the press belt, the fibrous web, and the permeable carrier belt at least in a part region of the press zone. The permeable press belt is configured to generate a pressing pressure in the press zone when a tensile stress of at least 20 kN/m is applied and the contact side is adapted to a quality of the fibrous web produced.

摘要： Methods for dewatering a fiber suspension in a twin-wire press, having a lower wire and an upper wire, and a first and a second dewatering table, which supports the wires such that a dewatering space is defined by the wires, are disclosed. The wires transport the fiber suspension under compression of the wires by the dewatering tables, such that the fiber suspension is dewatered and forms a fiber web between the wires. A separate pressing force is applied against one of the wires, such that this wire presses the formed fiber web via the second wire against one of the dewatering tables and further dewaters the fiber web. The separate pressing force is adjusted such that a desired dryness of the fiber web leaving the dewatering tables is achieved. A twin-wire press is also disclosed.

摘要： The present invention relates to a method for dewatering of a fibre suspension in a twin-wire press (2), according to which method the fibre suspension is fed to an oblong dewatering space (4), that is defined by an endless lower wire (6) and an endless upper wire (8) of the twin-wire press, against which wires lower and upper perforated dewatering elements are arranged outside the dewatering space, and the fibre suspension is dewatered in the dewatering space (4) during displacement of the wires, such that a flow of filtrate from the dewatering space (4) through the wires (6, 8) and the perforated dewatering elements is formed, filtrate that flows from the dewatering space through the wires is collected in outlet boxes (18, 20), that the pressure difference between the dewatering space (4) and at least an outlet box (18, 20) is adjusted by controlling at least a counter pressure that is applied on at least a portion of the flow of filtrate. In this respect the dewatering is optimised and the built-up of the fibre web is improved. The present invention also relates to a twin-wire press for carrying out the method.

摘要： A method and an apparatus for washing a fiber pulp mixture, whereby water and, with it, ash and other particle-type impurities are removed from the fiber pulp mixture. The fiber pulp mixture is fed between two wires in a dewatering section so that water and ash are removed from the fiber pulp through both wires, after which the wires and the fiber pulp between them are led to run along a curved surface to remove any extra water by means of the tension of the wires and centrifugal force.

摘要： A process for thickening a fibrous pulp suspension by guiding the suspension between a rigid first face and a flexible second face that move in relation to each other and form a converging draining gap, where the first face and/or the second face is/are water permeable, and where the process includes providing the suspension to be drained, forming from the suspension a fibrous pulp layer with a solid matter content of at least about 4% on at least one of the first face and the second face, guiding the fibrous pulp layer into the draining gap, applying a pressure differential in the draining gap via the second face to thicken the fibrous pulp layer, the pressure differential being formed by stretching the second face and pressing the first face and the second face toward each other to drain water from the fibrous pulp layer, and transporting the thickened fibrous pulp from the draining gap.
