Abstract
The disclosure relates to a method for producing a component of a rotor blade in that a vacuum film (16) is placed on a positive mould (1), layers (17) are laid on the positive mold (1), a negative mould (3) is pivoted over the occupied positive mold (1), the vacuum film (16) is then sealed from the negative mould (3), a vacuum is then drawn against the negative mold (3), and the negative mould (3) together with the layers (17) is then pivoted back.
Claims5
A method of manufacturing a component of a rotor blade comprising:
- placing a vacuum film (16) on a positive mould, whereby layers (17) are placed on the positive mould, the positive mould comprising an elliptical shape;
- pivoting a negative mould (3) from a first position to a second position over the positive mould;
- rolling the positive mould from the elliptical shape to a semi-cylindrical shape with the layers (17) placed thereon;
- sealing the vacuum film (16) on the negative mould (3);
- drawing a vacuum against the negative mould (3);
- and
- pivoting the negative mould (3) back to the first position with the layers (17).
