ABSTRACT:
A method for producing a spunbonded nonwoven fabric by extruding a linear sheet of filaments arranged parallelly side by side in the form of a curtain from a plurality of spinning capillaries, involving aerodynamical pulling off and drawing of the filament sheet, the filament sheet (8) which emerges from the drawing duct (12) or which is pulled off a spool being moved laterally crosswise by an air flow having periodically changing directions, the air flow being oriented alternately at an angle toward the filament sheet (8) as viewed in the horizontal plane.
