    摘要： A shoe roll pedestal structure comprises a pedestal (1) having an axle hole (11) and an axle stub (3) accommodated in the axle hole (11). The axle hole (11) in section has a polygon shape. At least one of surfaces (11a) of the axle hole (11) is a torque surface. Here, a torque surface is a surface, which can be machined with a higher degree in accuracy than a remaining reference surface, or surfaces of the axle hole (11), and which absorbs a torque. The axle stub (3) in section has a polygon shape corresponding to the polygon shape of the axle hole (11). Each surface of the axle stub (3) corresponding to one of the at least one torque surfaces of the axle hole (11) is in abutment against the corresponding torque surface of the axle hole (11). A number of torque surfaces of the axle hole (11) and the axle stub (3), respectively, is lower than a total number of surfaces of the axle hole (11) and the axle stub (3), respectively.

    摘要： The invention relates to a screening device for screening pulp suspensions and/or for stock preparation, which screening device (10) comprises a screening cylinder (12) and an inside the screening cylinder (12) located rotor (13) with foils (14) connected to the rotor (13) by foil arms (17), which screening device (10) comprises an inlet fitting (20) and a feed chamber (11) above of the screening cylinder (12) into which inlet flow of the pulp suspension is guided through the inlet fitting (20), which screening device (10) comprises a housing (25), which housing (25) has an inlet opening (28) for the inlet fitting (20). The screening device (10) comprises a flow guide (29, 30) extending from the inlet opening (28) in the housing (25) of the screening device (10) a distance inside the screening device (10) and that the flow guide (29, 30) inside the feed chamber (11) of the screening device (10) guides the inlet flow into the feed chamber of the screening device (10) and prevents the incoming inlet flow to meet the inlet flow already in the feed chamber (11) of the screening device (10).

    摘要： The invention relates to a method for measuring the moisture of a fiber web (W) in a tissue machine (10), which includes, as sub-entities, a forming section (11), a press section (12), a Yankee drier (13) and a reel (15), each of which performs one or more process stages (39.2) included in the sub-entity and where the fibre web is taken through the sub-entity via one or more rotating machine elements (41), of which one or more are equipped with a sensor assembly (24). In the method, the temperature of the fibre web is measured directly and/or indirectly in one or more sub-entities of a tissue machine by means of a sensor assembly arranged in the coating (43) disposed on the shell (31) and/or over the shell of a rotating machine element for establishing the temperature profile (21) in the cross direction (CD) of the machine, and the moisture profile (21') in the cross direction of the machine is generated on the basis of the temperature profile. The invention also relates to a corresponding system, a rotating machine element and a computer program product.

    摘要： The invention relates to a method for forming a multi-ply fiber web, in which at least part of the forming is done in a twin-wire forming part formed between a wire (10) for the bottom layer of the multi-ply fiber web and a wire (20) for the top layer of the multi-ply fiber web, in which the layers for the multi-ply fiber web are joined and treated layers combined in the twin-wire part. At least part of sizing of the multi-ply fiber web is provided by applying sizing agent in form of foam by a curtain type application device (C10; C20) in between at least two layers of the multi-ply fiber web in forming section of a multi-ply fiber web production line. The invention also relates to a forming section for a multi-ply fiber web comprising at least one twin-wire forming part formed between a wire (10) for the bottom layer of the multi-ply fiber web and a wire (20) for the top layer of the multi-ply fiber web, in which twin-wire part in the layers for the multi-ply fiber web are joined and treated layers combined. The forming section comprises at least a curtain type application device (C10; C20) for applying sizing agent in form of foam by in between at least two layers of the multi-ply fiber web in forming section of a multi-ply fiber web production line.
