PROBLEM TO BE SOLVED: To provide a stabilized filament drawing device for a meltspinning apparatus, increasing stability and guide of air-carried filaments falling from a drawing device to a collector. SOLUTION: The stabilized filament drawing device applies a high-velocity flow of air to attenuate the filaments, which are discharged from a device outlet in a discharge direction. The filament drawing device includes multiple inclined guides adjacent to the outlet that cause the high-velocity flow of air to deviate from the discharge direction by the Coanda effect. The filaments, which are entrained in the high-velocity process air, likewise deviate from the discharge direction. The guides are arranged such that spaces are absent between adjacent guides.
