ABSTRACT:
An air gun apparatus which permits stable, fine spinning and is capable of discharging fine filaments at a certain degree of dispersion and affording a non-woven fabric of uniform shape is provided. The air gun includes an air nozzle and an accelerator tube. The air nozzle has a filament inlet and outlet. The filaments are discharged from the filament outlet while being pulled by compressed air. The accelerator tube is formed at a specific diameter to length ratio and is connected to the air nozzle in the filament discharging direction. The non-woven fabric producing apparatus is provided with a guide tube and a separator nozzle, with an air flow rate regulator being disposed between the guide tube and the separator nozzle. The air flow rate regulator has an exhaust port for exhausting to the exterior a portion of the compressed air which is used for carrying the filaments.
