A molten yarn take-up device, comprising a cooling device disposed on the underside of a spinneret having cooling air inlet parts surrounding around spin-out yarns, ejector parts connected to the underside of the cooling air inlet parts and blowing compressed air around the spin-out yarns, and airflow guide pipes connected to the underside of the ejector parts, characterized in that the cooling air led from the outsides to the insides of the cooling air inlet parts is moved in the direction of running of the spin-out yarns so as to increase the velocity of the cooling air through the airflow guide pipes.
