1. Förfarande för framstälining av en rörformig extrusions-produkt med ett presshuvud, där blandningen av massaström-ningar sker med hjälp av enligt radialturbinprincipen an-ordnade, pä en statoryta belägna styrvingar (6) och pä en rotoryta belägna löpvingar (7), kännetecknat därav, att de av en smält plastmassa eller en smält/gasbland-ning bestäende massaströmningarna leds tili en eller flera blandningszoner bildade av de motstäende ytorna i press-huvudets pressenheter (la,Ib,2a), vilka utgörs av tvä stator-skivor (la,Ib) och en mellanliggande rotor (2a), frän den yttre periferin i radiens riktning inät frän ätminstone tva i förhällande tili rotorn (2;2a-2c) radiellt symmetriskt pla-cerade punkter, frän vilka zoner massaströmningarna leds vidare frän rotorernas (2;2a-2c) inre periferi pä i och för sig känt sätt som en rörformad strömning tili ett munstycke (3).
2. Förfarande enligt patentkravet 1, kännetecknat därav, att rotorerna erhäller väsentligen hela sin rörelse-energi ur massaströmningen genom förmedling av de pä stator-ytan belägna styrvingarna (6) och de pä rotorytan belägna löpvingarna (7).
3. Förfarande enligt patentkravet 1, kännetecknat därav, att rotorerna (2;2a-2c) erhäller en väsentlig del av sin rörelse-energi genom förmedling av en yttre rotations-kraft (13,14), som roterar rotorerna frän ätminstone tvä pä deras yttre periferi i förhällande tili rotorn radiellt symmetriskt placerade punkter.
4. Förfarande enligt nägot av ovanstäende patentkrav, kännetecknat därav, att det vid framställning av en rörformig extrusionsprodukt, som bestär av flera än ett materialskikt, används i presshuvudet en pressenhet (la,Ib, 2a) för varje materialskikt som skall framställas. r 9 79802
