Abstract
The invention relates to a water bar comprising nozzle parts for a suction chamber to apply jets to fabrics, knitted fabric webs, or nonwoven fabrics copoosed of staple fibers, endless filaments, or cellulose fibers, also in several layers, or mixtures thereof, and a suction area which is located on the bottom side of the suction chamber and is used for sucking off spraying water. The aim of the invention is to largely prevent spraying water or spraying mist in the region of the water jet that is discharged from the water jet beam. Said aim is achieved by assigning an air supplying device to the water bar and/or the suction chamber, said air supplying device being provided with at least one outlet which is located in the region of the water bar and extends to the region of the nozzle ports of the water bar.
