Claim:
A method for manufacturing wind turbine blades having a composite shell structure comprising a matrix material and a fibre reinforcement material by use of a resin transfer moulding process, characterised in that the method comprises a manufacturing line ( 30 ), where wind turbine blades are formed in a number of moulds ( 40 , 50 , 60 ), each of the number of moulds ( 40 , 50 , 60 ) comprising at least one mould part ( 41 , 51 , 61 ) comprising a mould cavity ( 42 , 52 , 62 ), wherein the manufacturing line ( 30 ) further comprises a gantry means ( 35 ) movable along the manufacturing line ( 30 ), the method comprising the following steps: a) arranging fibre reinforcement material in the at least one mould cavity ( 42 ) of a first mould ( 40 ) using the gantry means ( 35 ), b) moving the gantry means ( 35 ) along the manufacturing line ( 30 ) to a second mould ( 50 ), c) supplying curable matrix material into the at least one mould cavity ( 42 ) of the first mould ( 40 ), while substantially simultaneously arranging fibre reinforcement material in the at least one mould cavity ( 52 ) of a second mould ( 50 ) using the gantry means ( 35 ), wherein the second mould ( 50 ) is arranged in substantially longitudinal extension of the first mould ( 40 ) and/or a third mould ( 60 ) is arranged in substantially longitudinal extension of the second mould ( 50 ).
