Claims (9)

1. Fremgangsmåde til formning af en profil for en hul vinge for en vindmølle, hvilken fremgangsmåde omfatter at lægge et første kompositfiberlag (101) ud på en første formflade af et første formelement (110), hvor den første formflade svarer til en første profilsektion af den hule vinge, der skal fremstilles, kendetegnet ved, at det første kompositfiberlag (101) er større end den første formflade, således at det første kompositfiberlag (101) danner en overskydende sektion (103), som strækker sig ud over en kant (104) af den første formflade, og fremgangsmåden er kendetegnet ved, at den yderligere omfatter: at lægge et andet kompositfiberlag (102) ud på en anden formflade af et andet formelement (120), hvor den anden formflade svarer til en anden profilsektion af den hule vinge, der skal fremstilles, at lægge en pose (201) i en sammenklappet tilstand ud på det første kompositfiberlag (101), at fastgøre posen (201) og det første kompositfiberlag (101) til den første formflade, at dreje det første formelement (110) vertikalt, efter posen (201) og det første kompositfiberlag (101) er blevet fastgjort til den første formflade, at forbinde det første formelement (110), som er blevet drejet vertikalt, med det andet formelement (120) på en sådan måde, at den første formflade og den anden formflade svarer til profilen af den hule vinge, der skal fremstilles, hvor forbindelsen omfatter en tilpasning af det første formelement (110) til det andet formelement (120) på en sådan måde, at den overskydende sektion (103) delvist overlapper med det andet kompositfiberlag (102) i det andet formelement (120), og at pumpe posen (201) op på en sådan måde, at det første kompositfiberlag (101) presses mod den første formflade, og det andet kompositfiberlag (102) presses mod den anden formflade, således at det første kompositfiberlag (101) og det andet kompositfiberlag (102) forbindes for at danne den profil, der skal fremstilles.
2. Fremgangsmåde ifølge krav 1, hvor fastgørelsen omfatter udsugning af luft mellem posen (201) og den første formflade, således at posen (201) og det første kompositfiberlag (101) fastgøres til den første formflade ved undertryk.
