Abstract

The present invention relates to a method of producing a transversely aligned web comprising the steps of extruding melted resin from a spinning nozzle to direct the metal resin downward, blowing off a primary airflow at a high temperature and at high velocity from an annular primary airflow nozzle, blowing off a pair of secondary airflows at a high temperature from a pair of secondary airflow nozzles, colliding with the pair of airflow blown off from the pair of secondary airflow nozzles each other below the spinning nozzle, spreading the colliding secondary airflow at least partly in the width direction of the conveyor, and piling on the conveyor the spun filaments so that transversely aligned web is formed of the filaments which are aligned in the width direction of the conveyor.
