1. A method of manufacturing a wind turbine blade (10) having a profiled contour including a pressure side and a suction side, and a leading edge and a trailing edge with a chord having a chord length extending therebetween, the wind turbine blade extending in a spanwise direction between a root end and a tip end, the method comprising the steps of:
providing a first shell half (61) and a second shell half (62);
providing a shear web (64) having a first edge (65) and an opposing second edge (66);
attaching the first edge (65) of the shear web (64) to an inner surface (67) of the first shell half (61);
providing at least one guide member (70), the guide member comprising a hollow body (71) and a guiding surface (72);
mounting the at least one guide member (70) onto an inner surface (68) of the second shell half (62), wherein the guide member (70) is mounted adjacent to a predefined shear web mounting region (69) on the inner surface (68) of the second shell half (62), such that the guiding surface (72) forms an angle with the inner surface (68) of the second shell half (62) at the shear web mounting region (69);
bringing the first and second shell halves (61, 62) together while guiding the second edge (66) of the shear web over the guiding surface (72) of the guide member towards the shear web mounting region (69); and
attaching the second edge (66) of the shear web (64) to the shear web mounting region (69) of the second shell half (62),
wherein the at least one guide member (70) further comprises:
a base part (74) for attachment to the inner surface of the second shell half, the base part having a front end (74a) and an opposing back end (74b);
a first front part (75) extending from the front end (74a) of the base part (74) and oriented substantially perpendicular to the base part (74), a transition between the base part (74) and the first front part (75) defining a right angle;
a second front part (76) which extends from the first front part (75) at an angle relative to the first front part (75), wherein the guiding surface (72) of the guide member is provided by the outer surfaces of the first front part (75) and the second front part (76);
a back part (77) extending from the back end of the base part and oriented substantially perpendicular to the base part; and
a curved section (78) which extends between the back part (77) and the second front part (76).
