Definitions

  • the invention relates to a spinner for melt-spinning a plurality of filaments according to the preamble of claim 1.
  • a spinner is part of a melt spinning apparatus for continuously producing synthetic filaments.
  • the spinner head allows extruding a polymer melt into a plurality of strand-like filaments, which are combined to form a plurality of synthetic filaments.
  • Such spinning heads usually have at their lower sides a nozzle plate containing a plurality of nozzle bores through which the polymer melt is pressed to extrude the filaments.
  • the filaments are then brought together in a spinneret downstream thread treatment device to multifilament threads, solidified and post-treated and finally wound into coils. It is quite common to produce one or more threads per spinner. For example, tendencies have recently been observed that spinning heads in particular are used to produce two multifilament threads per spinning head.
  • Such a spinner is for example from the WO 2005/098098 A1 known.
  • the known spinner has for this purpose a round nozzle plate containing a plurality of nozzle bores.
  • the round nozzle plate is associated with a filter plate for receiving two separate filter elements which are connected by two separate melt inlet channels in an inlet plate with a melt distribution system.
  • Such plates are usually held in a housing which is releasably connected to a nozzle carrier.
  • the housing is to be repeatedly connected to the nozzle carrier.

  • the connection can be carried out by a thread through a bayonet lock, such as for a single-threaded spinner in the DE 38 18 017 A1 is described.
  • the invention is therefore based on the object to design a spinning head of the type mentioned in such a way that a quick and safe replacement of the round nozzle plate and the filter elements is possible.
  • Another object of the invention is to provide a spinnerette with two filter elements which allows high melt throughputs.
  • the object according to the invention is achieved in that the inlet plate has an outer shaping on the circumference and is held against rotation on the nozzle carrier and that the housing has an internal molding at a plug-in end, by which the housing can be connected to the outer molding of the inlet plate.
  • the invention is separate from the design principle in which the interchangeable components of a spinner are pre-mounted in a housing by an inlet plate and are bolted to the nozzle carrier as a nozzle package.
  • the inlet plate with the two melt inlet channels is held against rotation on the nozzle carrier and used as a fastener. In that regard, relative movements on the inlet plate due to assembly and disassembly can be avoided.
  • the development of the invention is particularly advantageous in which the filter plate has a plurality of outstanding guide pins which protrude into a plurality of centering openings of the inlet plate.

  • Such hollow cylindrical filter elements also have the particular advantage that large filter surfaces can be realized and thus high melt throughputs can be achieved.
  • the filter elements are in this case preferably formed by an inner support tube with a perforation and an outer filter jacket, which are connected at the ends of the filter element to a sealing edge, wherein the filter elements are identical in their diameter and their lengths.
  • this achieves high pressure stability, so that high melt pressures can be achieved when extruding the filaments. Furthermore, it is ensured that a high self-sealing installation position is achieved within the filter plate on each of the filter elements.
  • the filter elements lie with one of their sealing edges in each case on a circumferential holding web of the filter plate.
  • the opposite sealing edges are sealed by a pressure piece, which act with a sealing collar on the sealing edges of the filter elements.
  • the distributor elements are formed within the filter openings by a pressure piece and a connecting piece, which cooperate to melt guide within the filter plate.
  • a melt inlet is formed by the connecting piece, which immediately facing the bottom of the inlet plate.
  • the melt supply to the melt inlet channels is preferably carried out by spinning pumps, so that each melt stream in a predetermined flow rate and operating pressure in filter elements and thus the nozzle holes of the round nozzle plate can be supplied.
