Abstract (en)

[origin: WO2015039971A1] The invention relates to an apparatus for producing multicoloured crimped composite threads. The apparatus has a melt-spinning device for extruding a number of filament bundles from a number of differently coloured polymer melts, a cooling device, a treatment device and a winding device. In order to extrude the filament bundles, a number of spinning nozzles are assigned to the melt generators. In order to allow uniform and energy-saving production of the composite threads, according to the invention each of the spinning nozzles has a round nozzle pack having a number of groups of nozzle bores, arranged in a segmented manner on an underside, which are connected to the melt generators via separate melt ducts and a number of melt inlets formed on a top side of the round nozzle pack.
