Abstract
The invention relates to an apparatus for detecting plugged sites and holes and for measuring of the water permeability properties of pervious machine fabrics. Plugged sites in a permeable fabric are detected by sensing water pressure pulses occurring in the nozzle at the moment when a stream of water flowing through the nozzle contacts a plugged site on a fast running fabric. The apparatus can be used on-line to simultaneously detect plugged sites and holes on a moving pervious fabric while monitoring its water permeability properties.
