发明名称 Process and apparatus for the production of nonwoven fabrics from extruded filaments
摘要 In an apparatus for the production of a non-woven fabric, a plurality of filaments (11) are extruded by a spinneret (2) into at least two groups spaced from each other to define an area of the cooling chamber without filaments and structures; the filaments are cooled by an air flow (Y) conveyed into the cooling chamber directed towards an intermediate area between said two groups of filaments, said area being located below an area of the spinneret without extrusion holes.
