Embodiment Construction

[0026] A first embodiment of the apparatus of the present invention for carrying out the method of the present invention for melt spinning and cooling a plurality of monofilaments is shown in FIGS. 1 and 2 . This embodiment is shown schematically in a view in FIG. 1 and in a transverse section in FIG. 2 . Therefore, if no specific reference is made to a particular figure, the following description applies to both figures.

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

[0028] Below the spinning nozzle device 1 is arranged a cooling device 3, between the spinning nozzle device 1 and the cooling device 3 a short spinning zone is formed in which the filaments travel without actively cooling them. The cooling device 3 has a blowing wall 4.1...

Abstract

The present invention relates to a method and apparatus for melt spinning and cooling a plurality of monofilaments, where after extrusion the monofilaments are guided as a curtain of monofilaments through a cooling zone and are cooled by a flow of cooling air blown transversely to the curtain of monofilaments Cool the monofilament. In order to avoid disturbing effects caused by air swirls in the edge region of the monofilament screen, an additional blowing air flow acts on the monofilaments running in the edge region of the monofilament screen in the cooling zone. For this purpose, the device according to the invention has at least one blowing device which is arranged on the end side of the spinning nozzle device.

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] In the production of spunbond nonwovens, it is known to extrude a large number of filaments in a spinning device, cool them together as a filament curtain and lay them down to form a nonwoven. For this purpose, drawing nozzles are usually used, which draw the monofilament curtain from the spinning device and feed it to a laying belt arranged below the drawing nozzles. To cool the freshly extruded filaments, a stream of cooling air transverse to the filament curtain is blown onto the filaments to solidify the filaments before entering the drawing nozzle. Such a method or apparatus is known, for example, from US6183684. [0003] In order to be able to meet the requirements for the homogeneity of the properties of the individual...
