Embodiment Construction

[0026] A first embodiment of the apparatus of the invention for carrying out the method of the invention for melt spinning and cooling a large number of filaments is shown in FIGS. 1 and 2 . This exemplary embodiment is shown schematically in one view in FIG. 1 and in a transverse section in FIG. 2 . The following description therefore applies to both figures if no one figure is specifically referred to.

[0027] The present exemplary embodiment has a spinning nozzle arrangement 1 which has a plurality of spinneret openings arranged preferably in a row on its underside. The spinning nozzle arrangement 1 is connected via a melt feed line 2 to a melt source (not shown here).

[0028] Below the spinning nozzle arrangement 1 a cooling device 3 is arranged, between which a short spinning zone is formed in which the filaments run without being actively cooled. The cooling device 3 has a blowing wall 4.1 extending parallel to the longitudinal sides of the spinning nozzle arrangemen...

Abstract

This invention relates to a method and an apparatus for melt-spinning and cooling a plurality of filaments which are processed to form a non-woven fabric or web. The filaments are guided after extrusion in the form of a filament curtain through a cooling zone and are cooled by a cooling air stream blown transversely to the filament curtain. In order to prevent the flow effects created by air swirls in the side edge zones of the filament curtain, an additional quenching air stream acts inside the cooling zone on each side edge of the filament curtain. For this purpose, the inventive apparatus comprises a quenching member positioned below each longitudinal end of the spinneret.

Description

technical field [0001] The invention relates to a method for melt spinning a plurality of monofilaments according to the preamble of claim 1 and a device for carrying out this method according to the preamble of claim 9 . Background technique [0002] It is known in the production of spunbonded nonwovens to extrude a plurality of filaments in a spinning device, cool them together as a filament curtain and lay them down to form a nonwoven. For this purpose, draw-off nozzles are usually used, which draw the curtain of monofilaments out of the spinning unit and feed them to a deposit belt arranged below the draw-off nozzles. To cool the freshly extruded monofilaments, a flow of cooling air transverse to the monofilament curtain is blown onto the monofilaments, thereby solidifying the monofilaments before entering the drawing nozzle. Such a method or device is known, for example, from US6183684. [0003] In order to be able to meet the requirements for uniformity in the proper...
