Abstract (en)
Provided is a nonwoven fabric manufacturing apparatus and a nonwoven fabric manufacturing method capable of equally coping with minute dimensional differences while reducing cost in response to various dimensional requirements. The nonwoven fabric manufacturing apparatus includes a die 2 having a nozzle row 20, a resin supply means 3 supplying the thermoplastic resin to the die 2, a hot air supply means 8 supplying hot air to a thermoplastic resin extruded from the nozzle row 20 of the die 2 to draw the thermoplastic resin into fibers, and a collector 5 having a conveyor belt 11, the collector 5 collecting the thermoplastic resin that has been drawn into fibers to form a nonwoven fabric web 12 by the self-fusion property.
