A process for the high speed production of pre-oriented yarns from synthetic linear polymers, in particular polyesters, comprising the steps of melt spinning the polymer by extrusion through a spinneret and, before winding up the extruded filament bundle, causing said bundle to pass through a zone wherein the ambient gas, in particular air, is caused to move in a direction parallel to and concurrent with that of the filament bundle progressing towards the wind up means.
