Abstract
Device with a nozzle beam for producing fluid streams for striking the fibers of a web of goods by streams.The fluid spraying against the underside of the nozzle beam must be captured. For this purpose, a device is used Fat is located to the side of the nozzle beam over its length. A funnel-shaped slot is provided at the edge of the nozzle beam, at whose inner end a suction slot approximately 2 mm high is formed. If a sufficiently low vacuum is connected to the otherwise completely enclosed device, all of the drops from the underside of the nozzle beam can be sucked up safely for the goods to be needled, including a spray fog.
