Abstract
Devices for water needling consists of a nozzle beam that is located transversely above the fiber web to be compacted. The water emerges in fine streams at high pressure from a plurality of nozzles and tangles the fibers to compact them, to change the surface, and to braid the fibers of the tissue or the like. Since this web must be guided past the nozzle beam, a lengthwise striping develops. In order to influence this advantageously, according to the invention the nozzle beam is caused by a vibrator to perform quite specific transverse oscillations. The resultant zigzag movement, with the generated groove depressions being located with their edges adjacent, produces a completely smooth surface without significant plastic elevations.
