Patent ID: 8641406

Claim:
A device for the production of rotor blades ( 1 ) for wind power plants comprising: a multi-part manufacturing mold ( 20 , 21 , 22 ) for a rotor blade ( 1 ) that along a longitudinal extension, which extends from a rotor blade root ( 2 ) substantially to a rotor blade tip ( 3 ), has at least one area in which the rotor blade ( 1 ) has an aerodynamic airfoil section ( 4 ), which has an airfoil leading edge ( 5 ) and an airfoil trailing edge ( 6 ) that are connected via a suction side ( 8 ) and a pressure side ( 7 ) of the airfoil section ( 4 ), wherein the multi-part manufacturing mold includes at least two partial molds ( 21 , 22 ; 34 , 35 ) that are provided for at least two shell parts ( 23 , 24 ; 36 , 37 ) of a rotor blade ( 1 ), of which a first shell part ( 23 ; 36 , 37 ) and a second shell part ( 24 ; 36 , 37 ) lying substantially flat on each other in the area of the airfoil trailing edge ( 6 ) are to be connected together, wherein one of the partial molds ( 21 , 22 ; 34 , 35 ), in the area of the airfoil trailing edge ( 6 ), has a marking mold ( 30 , 32 ) extending in a longitudinal direction of the partial mold ( 21 , 22 ; 34 , 35 ) for generating a trimming marking ( 31 , 33 ) on a shell part ( 23 , 24 ; 36 , 37 ) in the area of the airfoil trailing edge ( 6 ) of the rotor blade ( 1 ), and wherein the marking mold is located inside the manufacturing mold at a location so as to contact an outermost layer of the shell parts.
