METHOD AND APPARATUS FOR COOLING MOLTEN FILAMENTS IN SPINNING APPARATUS A method for cooling molten filaments in a spinning apparatus where a plurality of molten filaments extruded from a die are cooled by cooling air blown out from a cooling apparatus and are taken up with a draft, wherein the temperature and/or volume of the cooling air blown from the cooling apparatus is controlled so that the cooling is performed stronger, in stages or continuously, from upstream to downstream.
