Abstract:
1. Nozzle beam on a device for generation of liquid jets for jet interweaving of the fibers of a fiber path, the beam consisting of an upper part extending over the operational width of the fiber path, and a lower part that is attached to it in liquid-sealed fashion, wherein a) a pressure chamber is arrayed in the upper part over its length, to which liquid under pressure is fed, and b) parallel to the pressure chamber, with an intermediate partition, a pressure-distributing chamber is provided, which is connected with the pressure chamber via liquid flow-through boreholes situated in the partition, and c) a nozzle strip is provided on the lower part, having boreholes for a nozzle chamber and being supported in liquid-sealed fashion, and d) the pressure-distributing chamber runs out into a slot in the area that lies opposite the liquid flow-through boreholes, the slot terminating at the boreholes of the nozzle strip, and e) in the pressure-distributing chamber between the liquid flow-through boreholes and the slot, a baffle is situated over the length of the slot, which over its length and over its cross section is situated in the pressure-distributing chamber so as to allow free flow around it, characterized in that the baffle is not screwed to the nozzle beam, but rather inserted into it and can be removed from it, the baffle being held by spacers in a centric or eccentric position.
