Embodiment Construction
[0019] An apparatus for manufacturing filaments 1 from thermoplastic composites is shown. The apparatus has a melt blown die 2. The meltblowing die 2 is equipped with a composite guide core 3, which in the present embodiment as an example has a row of nozzles 4 to discharge the molten composite. This row of nozzles 4 extends perpendicular to the horizontal plane of the paper.
[0020] There are supply devices (not specifically shown) on both sides of the composite guide core 3, with this device, the filament 1 near the hole of the nozzle 4 can receive the first jet of air on both sides. In the example of this embodiment, the received first spray air on both sides is represented by two arrows A. It can be seen from the figure that the first jet of air and the surface jets of the first jet of air form an acute angle to each other under the nozzle 4. The first jet air is fed through the gap 5 between the composite guide core 3 and the die lip 6 on both sides. Advantageously, the die ...
