  • Patent number: 6604928
    Abstract: A filtering device for a spinning head for producing plastic threads. The spinning head has a housing in which the plastic melt flows through a filter element under pressure before exiting the spinnerets. The filter element is provided with a filtering material that is subjected to an axial contact pressure through a distributor device, according to the degree of pressure of the melt. This contact pressure acts upon the sealing edges of the filter element to close the sealing gaps. The special geometrical configuration of the filter element and/or its elasticity guarantee advantageous filtering in terms of energy. The filtering system is resistant to pressure and provides good, permanent sealing.
