摘要： A method for controlling the moisture profile of a paper web or board web processed in a heated multi-roll calendar to optimize the qualities of the paper or board, especially gloss. The method is characterized in that the moisture measurement is carried out both on either surface of the web and as a through-measurement, and the measurement results thus obtained are specified by a thermodynamic model which calculates the moisture of the web in three layers, and that the results thus obtained are used for controlling the supply of moisture to the web.

摘要： Tension variations in the paper web on a paper machine are caused by successive draws and moisture fluctuations. Good strength properties require optimization of the draws. In addition, the tension variation induced by moisture must be minimized. The analysis of local modulus and the strain components can be used for determining optimal locations for profiling actuators in order to achieve good tension profile. Longitudinal strain components of the web, i.e. reversible elastic strain, permanent plastic strain and frozen-in strain relievable with water are continuously measured and determined and the variation of said longitudinal components is minimized by correcting the moisture content of the paper web in a dryer section of the paper machine and/or by optimizing the draws between dryer groups in the dryer section.

摘要： Optical radiation sources functioning on different optical bands radiate on different optical bands and focus optical radiation on a region in a web surface as pulses in such a manner that illumination areas of the pulses overlap on the plane of the web. At most one optical radiation band is focused on the web from the direction of the normal. The spatial intensity distribution of at least one optical band differs from the uniform distribution and the intensity distributions of at least two different optical bands differ from one another in a predetermined manner. A camera forms still images of the web surface region on each optical radiation band. An image-processing unit determines the surface topography of the web on the basis of the images. In addition, a controller may control the paper manufacturing process on the basis of the determined surface topography.

摘要： A perforated roll (10) of a fiber web machine includes a roll shell (19), holes (13) extending through the roll shell, and a sensing system (14) arranged in the roll shell. The sensing system (14) includes at least one pair of leads (16), to which one or more sensors (15) have been connected. At least one pair of leads is composed of flat leads (17.2, 17.2), which are arranged in the roll shell side by side. A prefabricated sensor sheet (26) may be prepared for a perforated roll of a fiber web machine, such that holes may be drilled therethrough to communicate with the roll shell holes (13).
