Abstract

En ekstruderingsdyse (10), særlig for bruk hvor nøyaktig sentrering av doren (20) er viktig. Dysen innbefatter et farste element (26) med en dor (20) som stikker frem fra denne og en ekstruderingspassasje (36) hovedsakelig på linje med doren, hvilke ekstruderingspassasje (36) har i en ende et tverrsnitt som korre-sponderer med en passasje (49) som befordrer ekstrudat fra ekstruder ingshodet og som, over sin lengde, går over i en ekstruderingspassasje (30) i den andre ende som minst delvis omgir dorens (20) rot. Dette element (26) er justerbart plassert i det ytre element (12), som sammen med doren (20) definerer et ekstruderings-munnstykke. Ettersom ekstruderingspassasjen (36). går gjennom det første element (26), er det mulig å anordne posisjoneringsinnretninger (52) for det første element (26) og doren (20) uten å komme i konflikt med ekstrudatets strømning.
