Definitions

  • the invention relates to a filter device for a spinning head and Spinning head for the production of plastic threads, which has a housing, in which the plastic melt before it emerges from the spinnerets under pressure flows through a filter element with a filter material that via a distribution device depending on the strength of the melt pressure experiences an axial contact force, the closing of Sealing gaps act on the sealing edges of the filter element.
  • melt spinning the polymer melt must immediately before passing through the nozzle plate of a fine filtration using a sand filter, Metal powder filter or filter candles are subjected.
  • EP 0 658 638 B1 it is known to melt the polymer by a plurality to run parallel arranged filter candles made of metal mesh with the Disadvantage that a uniform flow of all filter cartridges practically is excluded, with the result that individual filter cartridges are preferred soiled and all filter cartridges cleaned after a short period or must be replaced.
  • a spinning head is known from DE 42 27 114, in which the stability of the ring filter element due to a radial support is increased by a distribution device, but with the result that the filter element can be flowed through very unevenly.

Because the flow direction for the plastic melt over the entire length of the filter element evenly in one Direction is flowing, the flow is energetically favorable and the No artificial resistance is opposed to melt flow. By the protruding or recessed end of the filter material that the respective sealing edge forms is given the elasticity behavior the filter element a secure seal of the possible passage points guaranteed in the form of the sealing gap. Since the related Filter element can be created from standard components, especially from conventional ones Metal mesh filter materials, its manufacture is inexpensive.
  • the success according to the invention can also be according to the characterizing part of claim 2 achieve that at least at one end a flat sealing edge on the filter element is present, the overall rigidity of the filter element being chosen in this way is that the sealing gaps are closed under the contact pressure.
