A large number of water jets are necessary in order to stabilise water jets or general impingement of said water jets on a web of fabrics. Said jets exit from a nozzle strip (14) which is provided with a number of holes. A hole or holes can become blocked during use, making it necessary to clean of all the strips (14) in order to achieve a consistent treatment result. A device is arranged on the water strip in order to monitor the water jets exiting therefrom. In order to monitor the water-jets exiting therefrom, a device is arranged on the water strip, said device being able to change step back and forth, in the region where the water jets exit from the water strip, for monitoring purposes along one section of the length of said water strip.
