Abstract
A method for spinning a multifilament yarn from a thermoplastic material, where the filament bundle is cooled below the spinneret in a first cooling zone, first of all by means of at least one transverse blowing operation with a gaseous cooling medium and by means of an extraction means for the gaseous cooling medium which lies opposite said transverse blowing means, and subsequently the filament bundle is cooled further in a second cooling zone below the first cooling zone by automatic suction of gaseous cooling medium which is situated in the vicinity of the filament bundle.
