Abstract

Il presente trovato si riferisce ad una testa di estrusione per filati bicomponenti con filiera ad alta densità di fori che presenta la peculiarità di comprendere un gruppo di distribuzione per l'immissione di un primo componente lungo una prima direzione e per l'immissione di un secondo componente lungo una seconda direzione.Il citato gruppo di distribuzione immette i due componenti con un rapporto di distribuzione fra i due componenti prestabilito in una zona di passaggio in comunicazione con una filiera munita di fori che si sviluppano lungo direzioni sostanzialmente parallele a detta prima direzione e con una densità di fori superiore a 10 fori al cm2.
