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 composed 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.
A water bar (1a) with nozzle openings (10c) for a suction chamber (5a) for applying a jet to fabric, knitted fabric webs, or nonwovens (2), comprising several layers of staple fibers, endless filaments, or cellulose fibers or mixtures thereof and provided with a suction area (3a, 3b) on a lower side (5b) of the suction chamber (5a) for suctioning off the spraying water (4), characterized in that an air supply device (11a) is assigned to the water bar (1a) and the suction chamber (5a), which has at least one outlet opening (11c) and is located in the region of the water bar (1a) and extends into the region of the nozzle openings (10c) for the water bar (1a).
A water bar (1a) with nozzle openings (10c) for a suction chamber (5a) for applying a jet to fabric, knitted fabric webs, or nonwovens (2), comprising several layers of staple fibers, endless filaments, or cellulose fibers or mixtures thereof and provided with a suction area (3a, 3b) on a lower side (5b) of the suction chamber (5a) for suction off the spraying water (4), characterized in that an air supply device (11a) is assigned to the water bar (1a) and the suction chamber (5a), which is provided with at least one outlet opening (11c) in the area of the water bar (1a) and extends into the region of the nozzle openings or into the nozzle openings (10c) of the water bar (1a), wherein at least two outlet openings (11c) of the air supply device (11a) are arranged opposite each other and are embodied flat in the region of the outlet end and extend approximately parallel to the surface of the third segment (10f) or the second segment (10e).
