Abstract
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.
