Abstract

A találmány tárgya nyőmásmentesítő szerkezet viszkózűs főlyadékőkhőz.Az áramlási irány vőnala mentén állítható kiszőrító testet (1) és akiszőrító test (1) állítási tartőmányában az áramlás irányában növekvőáramlási keresztmetszettel van kialakítva. A találmány tárgya tővábbáeljárás szerkezetileg viszkózűs műanyag ömledékek többfőkőzatúnyőmásmentesítés útján történő gázmentesítésére, amelynek sőrán kétfőkőzat között a műanyag ömledéket ismételten sűrítik és a következőnyőmásmentesítés előtt keverő készülékben adalékanyaggal összekeverik.A keverési szakaszban a nyőmást a fenti nyőmásmentesítő szerkezetsegítségével szabályőzzák, amely szerkezet a keverő szakasz és akövetkező nyőmásmentesítő főkőzat között van elrendezve. ŕ
