Beschreibung
Zusammenfassung:	The invention relates to a device for melt spinning and cooling synthetic filaments. The device has a heated spinning beam which on the underside thereof carries at least one spinneret for extruding the filaments. A cooling device is arranged below the spinning beam which cooling device has a blowing chamber and a perforated cylinder which is arranged inside the blowing chamber and has a gas permeable wall. The perforated cylinder is arranged with an upper end at the spacing below the spinneret for receiving the filaments. In order to avoid deposits and condensation at the upper end of the perforated cylinder a separate heating means is provided according to the invention by way of which heating means the upper end of the perforated cylinder can be warmed.
