Abstract
The present invention relates to a method and system for manufacturing a wind turbine blade. The method comprising the steps of forming a cured blade element (102) of a first blade shell, forming a cured blade element (102) of a second blade shell, transferring the cured blade element (102) of the first blade shell to a first cradle (92), and transferring the cured blade element (102) of the second blade shell to a second cradle (94). Each cradle comprises a mould body (96, 98) having a moulding surface for abutting against a surface of the cured blade element to advantageously form a seal therebetween.

A method of manufacturing a wind turbine blade, the method comprising the steps of:
- forming a cured blade element (102) of a first blade shell;
- forming a cured blade element (102) of a second blade shell;
- transferring the cured blade element (102) of the first blade shell to a first cradle (92);
- transferring the cured blade element of the second blade shell to a second cradle (94), wherein each cradle comprises a mould body (96, 98) having a moulding surface (97), and wherein each cured blade element is arranged in its respective cradle such that the moulding surface (97), or a part thereof, abuts against a surface of the cured blade element (102);
- forming a reinforced section (104) on the cured blade element of the first blade shell in the first cradle;
- forming a reinforced section (104) on the cured blade element of the second blade shell in the second cradle;
- closing said first and second blade shells (100) to form a closed wind turbine blade shell;
- and
- bonding said first and second blade shells in said closed wind turbine blade shell to form a wind turbine blade.
A manufacturing system for the manufacture of a wind turbine blade formed from a pair of cured blade shells bonded together, the system comprising:
- a first blade mould (72) for forming a cured blade element (102) of a first blade shell;
- a second blade mould (74) for forming a cured blade element (102) of a second blade shell;
- a reinforcing station (90) comprising a first cradle (92) for receiving the cured blade element of the first blade shell and for forming a reinforced section (104) on the cured blade element of the first blade shell, and a second cradle (94) for receiving the cured blade element of the second blade shell and for forming a reinforced section (104) on the cured blade element of the second blade shell;
- and
- a closing mechanism operable to close said first and second blade shells to form a wind turbine blade,
- wherein each cradle (92, 94) comprises a mould body (96, 98) having a moulding surface, and wherein each cured blade element (102) is arrangeable in its respective cradle such that the moulding surface, or a part thereof, abuts against a surface of the cured blade element.
