摘要： A spunbonded web is produced by melting a thermoplastic polymer to form a melt, spinning the melt downwardly through spinnerets to form filaments, cooling the filaments, drawing the thus cooled filaments by take-off nozzles into the form of filament strands, passing the filament strands through guide tubes and by the guide tubes directing the thus guided filament strands downwardly therefrom toward a laydown apparatus, and laying down the filament strands in the form of a web on the laydown apparatus and moving the web in a take-off direction. Adjacent of the filament strands are guided, due to orientation of respective adjacent guide tubes thereof in different downward directions at respective different angles relative to the takeoff direction, to the laydown apparatus in respective different directions at said respective different angles.
