The process and apparatus for manufacturing spunbonded nonwoven fabrics is disclosed, wherein continuous filaments of organic polymers are extruded, stretched to orient same, and then arranged in fabric form on a moving conveyor. The filaments are arranged or distributed on the moving conveyor by impact from a deflector surface, wherein at least that portion of the deflector surface wherein the filaments are at their maximum width is vibrated. The spunbonded nonwoven fabrics produced are more homogeneous than similar fabrics produced without vibrating the deflector surface. The fabrics are suitable for conventional uses of spunbonded nonwoven fabrics, such as apparel backing, padding and the like. |
