A method of spinning filaments from a melt which comprises flowing said melt through openings in a nozzle plate to form a stream of said filaments, directing a coolant radially outwardly from the center of said stream through a porous wall of a dispersing head provided with a downstream baffle adjusted to partially reduce the inside pressures of the coolant adjacent to the baffle to a value lower than the outside pressure, the resistance of said coolant caused by the wall porosity satisfying the relationship 1.43x106m+2222 m2=p=-96.96 m+20202 m2 wherein m is the rate of flow of said coolant across the area of said porous wall in kg/h-cm2, and p is the pressure drop in Pa.
