摘要：
A melt blowing nozzle apparatus for producing a plurality of fiber strands from a polymer melt has at least one melt inlet and at least one process air inlet. The apparatus further has a nozzle plate having a plurality of small tubes, each having a capillary bore for extruding the fiber strands, and an extrusion plate arranged underneath the nozzle plate, which extrusion plate has a plurality of extrusion openings for blowing out the fiber strands, corresponding to the small tubes. Each extrusion opening encloses one of the small tubes with an air gap. To ensure mountability in case of a large number of small tubes, a channel system of a common distribution device is provided for connection and distribution of the melt inlet to the capillaries of the small tubes and for connection and distribution of the process air inlet to the extrusion openings of the extrusion plate.
