Abstract
A process for making a nonwoven fabric in which continuous fibers are evenly distributed and neither bundles nor lumps of the fibers, includes a guide box for continuous fibers being provided between extruding nozzles adapted to discharge the continuous fibers under hot air blast and a conveyor belt. The box has an upper end opening and a lower end opening being larger than the upper end opening. The continuous fibers are subjected to a suction effect provided from below the guide box so that the continuous fibers may be secondarily stretched and thereby thinned within the guide box.
