Abstract

The invention relates to a device for melt spinning a composite thread comprising a plurality of filament bundles. The device comprises a plurality of spinning means for extruding a plurality of filament bundles and a plurality of drawing and stretching means by which the filament bundles can be produced as partial threads having different extensions. In order to be able to extrude a plurality of filament bundles using as little equipment as possible, according to the invention, the spinning means are formed by a spinning nozzle device having a plurality of groups of nozzle holes on a nozzle plate, wherein the spinning nozzle device comprises at least one distributing means for generating unequal volume flows from a polymer melt, by means of which the filament bundles can be extruded in parallel.
