Abstract (en)
[origin: WO2014064029A1] A device for producing a spun-bonded fleece from synthetic filaments is described. The device has a spinning device, a cooling device, a stretching device, a guiding device and a stacking device. A cooling shaft of the cooling device, a processing shaft of the stretching device and a diffuser of the guiding device for guiding the filaments interact, wherein a cooling air is fed to the cooling shaft and a process air is fed separately to the processing shaft. In order to make possible a separation of the cooling air from the process air and obtain an even guiding of the filaments, according to the invention a short free path is formed between a filament outlet of the cooling shaft and a filament inlet of the process shaft in which the cooling air can be removed into the surroundings.
