Abstract
An apparatus for manufacturing a nonwoven fabric has a spinning mechanism having a plurality of nozzles for extruding filaments, and a conveyor for collecting and delivering the extruded filaments. Between the spinning mechanism and the conveyor, there are disposed a high-speed air stream generating mechanism for generating a high-speed air stream to carry the filaments extruded from the nozzles to attenuate the filaments, and an air stream vibrating mechanism for periodically changing the direction of the high-speed air stream in the machine direction of the conveyor.
