Abstract (en)
[origin: WO2007059914A1] The invention relates to a method for melt spinning and cooling a multifilament thread and to a device for carrying out said method. According to said method, a plurality of filaments is extruded from a polymer melt, said filaments being guided in a filament bundle and cooled by a cooling air stream that passes transversally across the filament bundle, the temperature of the cooling air that is evacuated during the cooling of the filaments being measured and monitored. To detect the cooled state of the filaments and the characteristics of the thread derived from said state, the temperature of the cooling air is measured at least at one measuring point inside the filament bundle. To achieve this, a temperature sensor is located inside the filament bundle between the spinneret and a thread guide that is allocated to the latter.
