Problems solved by technology

[0005] The modular division of the spinneret pack, although large production widths can be achieved in the production of nonwovens by joining groups of strands together, has the disadvantage that melt occurs on the extruded strand groups Differences in the melt that will result in different physical properties of the extruded strand group
In this regard, it is not possible to ensure uniform monofilament tufts over the entire production width of the nonwoven

Embodiment Construction

[0034] FIG. 1 schematically shows a view of a first embodiment of the device according to the invention. This embodiment shows an elongated spin beam 1 for receiving an elongated spinneret pack 5 arranged on the underside of the spin beam 1 . The spinneret assembly 5 is constructed in the form of a plate with an upper inlet plate 8 , a central perforated plate 11 and a lower spinneret 18 . The configuration of the spinneret pack 5 and the configuration of the plate parts 8 , 11 and 18 are drawn and further explained in detail below.

[0035] The spinneret pack 5 is connected to a plurality of spinning pumps 6.1, 6.2, 6.3 and 6.4 via a plurality of melt lines 7.1, 7.2, 7.3 etc. up to 7.20. The spinning pumps 6 . 1 to 6 . 4 are associated with a plurality of melt lines which are directly assigned to the inlet plate 8 . In this exemplary embodiment, a total of 5 melt lines are assigned to each spinning pump 6.1 to 6.4.

Abstract

The invention relates to a device for melt spinning of a linear filament bundle with a spinning beam for mounting a longitudinal spinning nozzle group. The spinning nozzle group comprises a nozzle plate on an underside with a number of nozzle drillings and an inlet plate on an upper side with at least one inlet channel, a distribution chamber being arranged between the inlet plate and the nozzle plate, connected to the inlet channel in the inlet plate and the nozzle drillings in the nozzle plate. According to the invention, a residence time for the polymer melt within the nozzle group is kept as constant as possible with a large production range by means of the inlet plate having several residence chambers connected to inlet channels, arranged at a separation from each other in the longitudinal direction of the spinning beam.

Description

technical field [0001] The invention relates to a device according to the preamble of claim 1 for melt-spinning row-shaped monofilament tufts. Background technique [0002] For the production of nonwovens, it is known that a plurality of thin strands or elongated fibers are extruded in a row-like arrangement. For this purpose, elongated spinneret packs are used which are held in a heated spinning (holding) housing. On its underside, the spinneret assembly has a spinneret in which a plurality of nozzle openings for extruding strands are contained. Various solutions are known in the prior art for feeding polymer melt fed from a melt source to the nozzle bore. [0003] A spinneret assembly is known from EP 1 486 591 A1, in which polymer melt fed from a melt source is fed via inlet channels of an inlet plate and guided into distribution chambers. The polymer melt passes from the distribution chamber via the perforated plate to the nozzle holes of the spinneret. In this case,...
