1. Indre dom til køling af rørformede tynde film (4) sammen med en ydre ringformet køletank (22), hvor den indre dorn (5) omfatter: en flerhed af køletrin til indefra at nedkøle smeltet rørformet tynd film (4) koblet til undersiden af en ringformet ekstruderdyse (1), fra hvilken den rørformede tynde film ekstruderes nedad fra en ringformet slids (3) af den ringformede ekstruderdyse (1); en rørstørrelsesstyrering (6) til at forme den smeltede ringformede tynde film til en ensartet cylindrisk tynd film; og en dræningsenhed i det nederste køletrin (10b), hvor indre flydende kølemiddel af det nederste køletrin (10b) ledes til den rørformede smeltede tynde film (4) i den modstrøms retning i den indre dorn (5) for at påføres og direkte køle den smeltede rørformede tynde film (4), og efterfølgende løber til dræningsenheden i det nederste køletrin, hvor det nederste køletrin (10b) er anbragt under rørstørrelsesstyreringen (6); kendetegnet ved, at dræningsenheden i det nederste køletrin (10b) omfatter en flydende kølemiddeludløbsåbning (16), en indre cylinder (10a) og en ringformet ring (11) tilvejebragt ved toppen af den indre cylinder (10a) til udløbsåbningsregulering, hvor det flydende kølemiddel af det nederste trin strømmer over en øvre del af den ringformede ring (11), og luft, som strømmer ind hver gang det flydende kølemiddel af det nederste trin løber til den tynde film (4), udluftes fra en udløbsåbning over den ringformede ring (11) til den flydende kølemiddeludløbsåbning (16).
