Abstract: 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.

Abstract: The present invention relates to equipment/apparatus, and the relative method/process, for the treatment of synthetic filaments, in particular for drawing said filaments, comprising at least two nozzles each provided with a main passage, through which said yarns pass, having a section variable between an inlet portion and an outlet portion and into which at least one supply channel opens to supply a fluid according to a preferential direction. Advantageously, the nozzles are provided in line and the sections of the main passage of the second nozzle have an area at least 3% larger than the corresponding sections of the main passage of the first nozzle.
