ABSTRACT OF THE DISCLOSURE A spray spinning nozzle for producing a substantially continuous filament from a molten synthetic resinous material includes a nozzle with a removable orifice from which a filament of molten material is emitted and a gas attenuation assembly which is laterally removable from the nozzle. The attenuation assembly includes at least three gas jets spaced about and radi- ally close to the nozzle axis for emitting high velocity jets which converge upon and contact the filament at a point along the axis in front of the ori- fice. Drag forces produced by the gas jets attenuate the filament to a thin diameter.
