Claim Text:
1. An apparatus for manufacturing a melt-blown fabric web, the apparatus comprising: a heat extruder configured and arranged for heating a thermoplastic resin composition and extruding a melted thermoplastic resin; a melt-blown fiber spinner configured and arranged to receive the thermoplastic resin extruded by the heat extruder and spin the thermoplastic resin as a melt-blown fiber in a filament form; a variable gas injector configured and arranged for injecting gas so as to collide with the melt-blown fiber spun from the melt-blown fiber spinner; and a collector for collecting the melt-blown fiber that has been spun from the melt-blown fiber spinner and has collided with the gas, to form a melt-blown fabric web, wherein a gas processor is connected to the variable gas injector to continuously change the speed and influx of the gas supplied from a gas generator at random and supply the changed gas, the gas processor comprising a chamber and a rotor disposed within the chamber, the rotor having vanes of different lengths on a circumference thereof for transferring the gas, the rotor being rotatable at non-constant speed by a rotation driver to push the gas introduced through an inlet tube of the chamber and discharge the gas through an outlet tube of the chamber.
