Embodiment Construction

[0024] exist figure 1 A view of a first embodiment of a device according to the invention for cooling an annular extruded monofilament tuft is schematically shown in . The device is here integrated directly on the spin beam 6 . The spin beam 6 supports the annular spinning nozzle 4 on its underside. The annular spinning nozzle 4 has a plurality of nozzle openings 4 . 1 which are formed uniformly distributed on the underside of the annular spinning nozzle 4 . The annular spinning nozzle 4 is coupled to a spinning pump (not shown here) in order to extrude the polymer melt.

[0025] The connection adapter 2 is held centrally with respect to the annular spinning nozzle 4 on the underside of the spin beam 6 . The connection adapter 2 supports the blowing flow generator 1 which is arranged below the annular spinning nozzle 4 . The air blow generator 1 is formed in this exemplary embodiment by an air blow nozzle arrangement 9 . The air blow nozzle arrangement 9 has two nozzle pl...

Abstract

The invention relates to a device for cooling a ring-shaped extruded filament bundle, which are extruded through a plurality of nozzle bores of a ring spinning nozzle. The device has a blower power generator, which has a radially encircling blower outlet and is arranged centrally below the ring spinning nozzle. The blower generator is held by a connection adapter which connects the blower generator with a supply air duct. In order to equalize the supplied cooling air immediately before entering the blower power generator, in particular with regard to a cooling air temperature, a flow barrier is made of an open-pore metal foam is preferably assigned to the connection adapter, preferably an open-pore aluminum foam.

Description

technical field [0001] The invention relates to a device for cooling annular extruded monofilament tufts / curtains according to the preamble of claim 1 . Background technique [0002] During melt spinning / melt spinning synthetic fiber slivers or filaments, a plurality of fine sliver-shaped monofilaments are extruded through the nozzle holes of the spinning nozzles. For this purpose, the molten polymer is fed to the spinning nozzle under high pressure. To form a fiber sliver or a plurality of filaments, a plurality of sliver-shaped monofilaments are combined in their entirety or in bundles. Before merging, the monofilaments are cooled by a flow of cooling air so that the molten state of the monofilaments is converted to a solidified state after being discharged from the nozzle hole. Of particular importance for the quality of the fiber sliver or filament is the uniform cooling of all the individual filaments. It is therefore known in particular for the production of staple / ...
