摘要： An apparatus for measuring the permeability of a circulating band, in particular of a dewatering band in a papermaking machine, having a nozzle from which a measuring fluid flows onto the band. In order to avoid undesired lifting of the nozzle off the band due to pressure peaks, the apparatus according to the present invention has a nozzle which can be pressed onto the circulating band with a constant contact pressure.

摘要： A water jet cutter for separation of a trim strip from a moving paper, cardboard, tissue or other type of fiber web, in a machine for the production and/or conversion of the fiber web, including at least one nozzle whose water jet is directed onto the fiber web. An advantage of the present invention is to simplify the construction of the device while maintaining at least equal operational reliability, and to enable installation above a pulper in order to eliminate the necessity for removal and extraction systems.

摘要： 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.

摘要： 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.
