    Abstract: An apparatus and a method for determining the permeability of a circulating band, in particular a water-absorbing dewatering band in a papermaking machine. The apparatus is equipped with a nozzle from which a measuring fluid flows onto or through the band. Fluctuations in the flow of the measuring fluid and in the nozzle exit pressure can distort the measurement of the permeability. The apparatus has a device for determining the speed of the band and/or a device for determining the nozzle exit speed and the nozzle exit pressure of the measuring fluid. These three measured variables are measured simultaneously, so that a fluctuation in one of these measured variables cannot impair the accuracy of the permeability measurement.

    Abstract: A method and apparatus for controlling at least one quality feature of a running material web, in particular a fibrous web, during its production, including a measurement system, an electronic control and/or an evaluation unit. The measurement system measures the quality feature on a running material web repeatedly over the entire width of the material web. The electronic control and/or evaluation unit determines the variability of the quality feature through a variance component analysis, which is conducted on the basis of the profile measure values of a measured value set including several consecutive CD profiles in the machine direction, the set having been recorded during a selectable previous time window. The result of this variance component analysis is also drawn on to control the quality feature.

    Abstract: A method of determining at least one property of moving clothing of a machine for producing and/or treating a material web, in particular a paper or board web, which includes the following steps: arranging a nozzle opposite the surface of the moving clothing; producing a jet acting on the clothing by way of the nozzle contacting the moving clothing; measuring a variable representative of the flow through the nozzle; measuring a variable representative of the pressure of the jet at the nozzle outlet; determining the speed of the jet at the nozzle outlet from the nozzle flow and the free surface of the jet medium at the point of contact with the clothing; and determining the speed of the jet at the entry into the clothing from the speed of the jet at the nozzle outlet and the speed of the clothing. By using the speed of the jet at the entry into the clothing at a given pressure of the jet at the nozzle outlet and entry into the clothing, the water permeability of the moving clothing is determined and/or at least one surface property of the moving clothing is determined. A corresponding apparatus is also specified.

    Abstract: A system for the computer-aided measurement of quality and/or process data during the production and/or conversion of a material web, in particular paper or board web, by way of correlation with raw measured data. The raw measured data is present in the form of other quality and process data during the production or conversion process. Measurements of quality parameters in the laboratory may also be incorporated in the raw measured data. The raw measured data is combined to form data sets which in each case are determined simultaneously. Specific laboratory or quality measurements are selected as target data which, by way of at least one soft-sensor algorithm running in a computer-based operation and linking unit, can be calculated from the other data serving as input data, and each data set containing measured data, which relates approximately to the same monitored volume of web and raw material, in particular paper and paper raw material.
