In a melt spinning apparatus, cooling system with a blower nozzle with slit-shaped outlet openings is used which is directed upon the yarns emerging from the spinning nozzle. The blower nozzle is provided with a bend immediately before its outlet opening through which the air stream is directed to the output of the yarns from the spinning nozzles. The bend is designed so that a rapid and effective cooling of all the extruded filaments takes place, even with a nozzle package with a large number of perforations, without having to provide several blower nozzles. A narrowing at a given distance before the outlet opening ensures even distribution of the flow profile produced over the entire outlet cross-section of the blower nozzle. Furthermore, the spinning nozzles are assigned an induction heating system in which induction coils are placed above the area over which the spinning nozzles extend.

The heat transmission from the heating box of a spinning beam to the nozzle package carried therein in a nozzle throat is improved in such a way that the fixing device for the package is provided with heat receiving elements. These elements are subjected to saturated vapor in operation and are provided with condensation surfaces so as to receive heat from the saturated vapor. The heat received is transmitted to the package via at least one heat bridge.
