Abstract
An apparatus for manufacturing a transversely aligned web has a spinning device provided with a plurality of nozzles for extruding molten polymer as filaments, and a conveyor on which the filaments spun by the spinning device are piled and traveling in a direction cross to the direction of array of the nozzles. The spinning device is provided with a high-speed fluid blowing unit for blowing a high-speed fluid in a direction parallel with a direction in which the filaments are extruded from the nozzles so as to attenuate the filaments. Further, the apparatus for manufacturing the transversely aligned web has at least one air stream vibrating mechanism for cyclically changing the flowing direction of the high-speed fluid blown from the high-speed fluid blowing unit in a direction cross to the machine direction of the conveyor. The filaments are vibrated in a direction cross to the machine direction of the conveyor, owing to the high-speed fluid by the air stream vibrating unit.
