摘要： The invention relates to a sealing arrangement (7) against a moving fabric (4b) in a paper machine or the like. The sealing arrangement includes a stiff sealing element (9) placed on the fabric's (4b) side on the entire width in connection with a paper sheet (4a) supported by the fabric (4b). The sealing element has been arranged on a support so that the location of the sealing element with respect to the fabric (4b) can be adjusted nearer to or, correspondingly, further from the fabric. As a sealing element there is at least a single-chambered labyrinth sealing (19).

摘要： A method and an apparatus for separating solid or drop-like particles from an air flow is provided. The air flows through a separator chamber between an electrode, ion generating means or like particle charging device disposed in the separator chamber, and a grounded collector surface, so that the particles are charged by the charging device and accumulate on the collector surface. The air flows along a substantially spiral path around the charging device in at least a part of the separator chamber so that due to the action of centrifugal force at least a portion of the particles pass toward the grounded collector surface at the periphery of the chamber. A small flow of purified air flows downwardly in a central part of the separator chamber so that it washes the charging device in the separator chamber.

摘要： The invention comprises a method and an arrangement in a paper machine or the like close to a moving web (29) usually supported against a wire (1), and a paper machine including such an arrangement, and a sealing device having several such arrangements (100). According to the invention, a movable sealing (5) is arranged in the drying section of a paper machine, between two regions (3, 4) with different pressures. Certain air amounts (V1, V2) are supplied to and/or discharged from each side of the sealing (5) in order to create certain pressures in said regions. Air can move between said regions only through certain paths. In normal operating situations the seal (5) according to the invention is automatically adjusted to the desired position in relation to the web.

摘要： A blow box (18) for supporting the web run in a paper machine or the like, which blow box comprises members for maintaining a negative pressure at least in one negative pressure region (24) between the wire (20) and the blow box. The members comprise a blocking member (30, 32), which is arranged, regarding the wire's running direction, at the beginning and/or at the end of said negative pressure region, which extends across the wire and projects towards the wire, and which is movable in relation to the blow box, and blowing members (34, 36), with which air is ejected with blows between said blocking member and the wire from said negative pressure region and/or with which air is prevented from entering this negative pressure region. The blocking member is connected to the blow box by a hinge member (40, 42), which allows the blocking member to rotate around the articulation point of the hinge member due to the pressure difference between the pressure acting on the blocking member's blocking surface (30′, 32′) directed towards the wire and the pressure acting on the blocking member's back surface (50, 50′) directed away from the wire.

摘要： A method for cleaning a web by removing dust and other particles therefrom in which a blowing is directed at a web to cause the separation of dust from the web and a suction effect is applied to the web to remove the dust separated from the web. A vortex flow may be produced before the dust separating blowing in the running direction of the web to prevent carriage of the dust into the environment and to compensate for the suction effect on the runnability of the web.

摘要： An assembly is disclosed treating a moving web (1) of paper or paperboard with a web treatment substance, the assembly comprising an application chamber (P2) located in a close vicinity of the moving web (1) and facing the web (1), whereby the chamber is delineated by the web (1), the walls (12) of the coater apparatus and sealing means (18, 24, 35) adapted to operate at the web ingoing and outgoing sides of the application chamber (P2). For application of the web treatment substance, the assembly includes at least one linear nozzle array incorporating at least one nozzle (21) for spraying the web treatment substance onto the web (1). The coater apparatus is divided into chambers so that a suction chamber (P3) is located behind the application chamber (P2) as seen from the direction of the web (1) and is adapted to communicate with application chamber (P2), and a flow is established into the suction chamber (P3) and the application chamber (P2) for removing mist and accumulations of the web treatment substance in such a manner that the pressure of the application chamber (P2) is made lower than the ambient pressure and the pressure of the suction chamber (P3) lower than that of the application chamber. In the assembly, the free flow direction of substances contained in the assembly is firstly from the surroundings into the application chamber (P2) and then from the application chamber (P2) to the suction chamber (P3) and means (22) serving to establish the flow.

摘要： A supply air system for supplying air e.g. into a machine room. The supply air system comprises a supply air unit (12), to which means are connected for supplying the supply air from the outside air to the internal space, and an air treatment unit (14) in which means (58, 64) are arranged for treating the air supplied into the internal space. The units are interconnected by at least one duct (16, 16′), equipped with a blower. The supply air system further comprises an air distribution plate or the like for distributing the treated air into the machine room. The above-mentioned units are mounted on top of each other, so that the supply air unit (12) is arranged above the air treatment unit, so that an air chamber (20) for the treated air is formed between said units. At least a part of the air chamber borders to said air distribution plate (18, 18′). The air treatment unit (14) is arranged to supply treated air, such as cleaned air and/or air regulated to a desired temperature, into said air chamber.
