Definitions

  • the invention relates to a device for melt spinning a row-shaped filament bundle according to the preamble of claim 1.
  • EPl 486 591 A1 discloses a spinneret package in which the polymer melt supplied by the melt source is fed via an inlet channel to an inlet plate and guided into a distributor chamber. From the distributor chamber, the polymer melt passes through a perforated plate to the nozzle bores of the nozzle plate. In this case, the distribution chamber extends substantially over the entire length of the nozzle package.
  • such systems basically have the disadvantage that only limited widths of non-woven shelves can be produced.

  • the execution of the device according to the invention in which the holes in the region of the separating webs penetrate the perforated plate in such an oblique manner, so that on the opposite bottom of the perforated plate over the surface of the perforated plate uniform hole distribution is present, has the particular advantage that despite separation of the distribution chamber a uniform over the entire production width distribution of the melt is achieved in particular in the adjacent plenum.
  • the filter elements are preferably assigned to the top of the perforated plate in the hole groups, so that a simple handling is possible.
  • a plurality of spin pumps which are supplied via a melt source, are assigned to the inlet channels in the inlet plate. In this case, an inlet channel or a group of inlet channels can each be assigned to a spinning pump.
