    Abstract: A web is passed over a surface (11) which is at least partly curved in the running direction of the web, which extends across the web in the cross direction, and which is placed at a distance from the web, in which connection an air cushion is formed between the moving web and the curved surface. The temperature and moisture of the web are measured indirectly by measuring the temperature and moisture of the air cushion by several detectors (41) which are in communication with openings (40) formed in the curved surface in spaced relationship with one another in the cross direction of the web.

    Abstract: The invention relates to a method in the process of manufacturing and/or finishing a fibre web, in which method said continuous and moving web, and/or a moving means related to the processing of the web, is monitored by at least one optical spectrum separating measurement device to determine at least one quality variable of said object for the purpose of controlling the quality or condition. According to the invention, spectral data is collected in synchronization with the movement from the object which is being examined and is in a progressive and/or rotating movement, by measuring electromagnetic radiation, which has been transmitted, reflected, or otherwise emitted by the object, in a temporally and spatially resolved manner. On the basis of this spectral data, a two-dimensional quality variable chart is formed, which is substantially continuous in the direction of movement of the object and presents at least one quality variable of the object, and in order to determine the characteristics of the object and/or to detect defects in the object from said continuous quality variable chart, local deviations and/or discontinuities are detected in said continuous quality variable chart, especially in the direction of movement. The cause of these deviations and/or discontinuities is identified on the basis of the periodicity of said phenomena in the direction of movement.

    Abstract: An arrangement for removing condensate from an interior of a drying cylinder in a paper machine and a method for regulating the removal of such condensate. The arrangement includes a steam pipe through which steam is passed into the space in the interior of the drying cylinder, and a condensate pipe and fluidly connected syphon pipe through which condensate is removed from the interior of the drying cylinder. The steam pipe and the condensate pipe are passed through a revolving axle journal of the drying cylinder. The arrangement also includes a syphon support attached in the interior of the drying cylinder to revolve along with the drying cylinder and support the syphon. A support bearing is arranged to attach to the syphon support and the syphon support is connected with the construction of condensate and steam pipes.

    Abstract: An arrangement in connection with the press and dryer section of a web-forming machine includes first and second devices for transporting the web. The second device includes a dryer wire and a roll arranged to support it. In the arrangement there is an open gap between the first and second devices, across which the web is arranged to be transferred, so that the web and the dryer wire form a closing throat. The arrangement further includes a deflector before the open gap in the direction of travel of the dryer wire, which is arranged close to the dryer wire, in order to restrict the air layer travelling with the dryer wire, and thus to prevent the formation of an excess pressure in the closing throat.
