Abstract

See full text

Distributor of polymeric filament for spunbond and/or melt-blown type implant expanding along a main plane between a first interface side, to be coupled with an extrusion head, and a second interface side, to be coupled with a spinneret. Including distribution holes distributed within an extrusion area defined on the first side parallel to the main plane, extending along respective secondary axes transverse to the main plane from the first to the second side. Each defining a countersink converging from the first to the second side and delimited by perimetrical edges at the first side. Each perimetrical edge of a given hole is at least partially coincident with part of the perimetrical edges of other holes positioned around the given hole to realise a distribution surface, defined by the whole of the areas enclosed by the perimetrical edges, at least 80% of the extrusion area.
