Claims (15)

1. En fremgangsmåde til fremstilling af et aerodynamisk skallegeme (170) til en vindmøllevinge (10), hvor det aerodynamiske skallegeme omfatter en fordybning (176) til placering og forbindelse til en bjælkeflange (160) (eng. spar cap) i fordybningen, hvor fremgangsmåden omfatter følgende trin: a) tilvejebringelse af en første støbeformsdel (150), der har en første formoverflade, som definerer en del af det ydre af det aerodynamiske skallegeme, b) oplægning af fiberforstærkningsmateriale og også sandwichkernemateriale (167, 169) i den første støbeformsdel på den første formoverflade, c) placering af en eller flere indsatser (190, 196, 198), der har en ydre form, som svarer til i det mindste sider af fordybningen i det aerodynamiske skallegeme, d) forsyning af resin til fiberforstærkningsmaterialet og sandwichkernematerialet, e) hærdning eller forkonsolidering af resinen, og f) fjernelse af den ene eller flere indsatser.
2. En fremgangsmåde ifølge krav 1, hvor den ene eller flere indsatser har en ydre form, der svarer til i det mindste en del af en ydre overflade af bjælkeflangen.
