    摘要： A method for increasing the drying capacity of a steam group (6) in a drying section of a pulp or paper machine. According to the method, a main steam flow (3) having a first steam pressure is fed to the steam group (6), the main steam flow (3) is conducted to at least one thermocompressor (9), which is driven by motive steam (4) having a second steam pressure, which is higher than the first steam pressure, and the output steam (13) of said at least one thermocompressor (9) is fed to the steam group (6), the steam pressure of the steam that is fed to the steam group (6) being higher than the first steam pressure.

    摘要： A method for analysing in real-time in a paper machine or board machine the surface structure of a web (1) of paper or board which method comprises the direction of an imaging system towards a pre-determined area (3) of the web (1), the arrangement of an illumination system to illuminate the region from a pre-determined direction with obliquely incident light, and the arrangement of an image analysis system in association with the imaging system. Furthermore, the method comprises, according to the invention, an image capture step (7) in which the imaging system is caused to take several digital images of the web under the said oblique incident illumination and during a pre-determined period, which images form an image sequence that images a series of surface sections (4, 4’, 4’’) along a band (8) in the web (1), and an evaluation step (9) that is carried out by the image analysis system and which comprises an image analysis step (11), which in turn comprises a first analysis operation (16) in which the variance of the pixel values in each pixel row in each image in the image sequence is determined within a pre-determined wavelength band, and a second analysis operation (17) in which the mean value of the variances of all pixel rows of all images in the image sequence is calculated. The invention also concerns a device for the execution of the method.

    摘要： The present invention relates to a method for the manufacture of a lumber element comprising at least one outer surface, at least one edge surface and at least one outer corner. The method comprises steps to round off the outer corner and to provide it with grooves comprising parallel ridges (13) and tracks (14) in the grain direction of the lumber to improve the paint-absorbing ability of the surface. The invention relates also to a lumber element comprising at least one outer corner which is provided with such grooves.

    摘要： Paper or paperboard laminate composed of at least one bulk-promoting layer, here termed bulk layer (1), 40-98% of which is composed of cellulose fibres with a freeness value of 550-950 ml CSF, and on at least one side of the bulk layer at least one secondary layer (3a, 3b'), which has a greater density than the bulk layer, the secondary layer and bulk layer being joined indirectly to one another over basically the whole of their opposing surfaces and the laminate having a bending stiffness index greater than 2.5 Nm7/kg3, but less than 14 Nm7/kg3, calculated as a geometric mean value for machine direction and cross direction. According to the invention a thin intermediate layer (2a), which has a higher drainage resistance than the bulk layer and has been formed together with the bulk layer, is arranged between the said bulk layer (1) and secondary layer (3a, 3b').

    摘要： A device and a method for on-line control of the fibre direction of a fibre web (8), being manufactured from stock delivered from a headbox (3) through a discharge opening (11) defined by movable lips (9, 10), while using a fibre direction meter (12) located downstream and actuating members (14), which are arranged along thelips for regulation of the discharge opening as a response to individual control signals, each being a function of measured fibre direction values, wherein a control unit (13) receives the measured fibre direction values, calculates the control signals, and transmits these to the actuating members. According to the invention, the control unit identifies an array of fibre direction values, originating from positions in the cross direction of the fibre web which correspond to the positions of the actuating members. The control unit then compares the array of fibre direction values with an array of desired fibre direction values.
