Method for applying fibre material on a vertical surface of a web of a wind turbine blade

1. A method for applying fibre material on a vertical surface to form a web of a wind turbine blade, the method comprising:

positioning a vertical surface in a mould for a wind turbine blade at a position corresponding to a position of a web of the blade;

spraying an adhesive on the vertical surface;

applying fibre material on the sprayed surface directly in the mould during layout of fibre material in the mould;

spraying additional adhesive on the fibre material for another layer of fibre material;

applying another layer of fibre material on the sprayed fibre material; and

injecting the fibre material on the vertical surface and in the mould with a resin during a resin injection process for the mould.

2. The method according to claim 1 , wherein

the fibre material is unrolled from a reel.

3. The method according to claim 1 , wherein

a glass fibre material and/or a carbon fibre material and or a synthetic fibre material is used as the fibre material.

4. The method according to claim 1 , wherein

a fibre material in the form of a mat or a fabric is used.

5. The method according to claim 1 , wherein

a vertical surface is used which is made of wood or foam.

6. The method according to claim 1 , wherein

fibre material is applied on both sides of the vertical surface.

7. The method according to claim 1 , wherein

the resin is injected in a vacuum assisted resin transfer molding (VARTM) process.

8. The method according to claim 1 , wherein

the step of spraying an adhesive and/or the step of applying a fibre material is performed by an automatic actuator or an industrial robot.

9. The method according to claim 8 , wherein

an actuator or a robot is used comprising a means for exerting pressure to an applied fibre material.

10. The method according to claim 1 , further comprising selecting the adhesive to be of a composition which is desolved by the injected resin.

11. A method for applying fibre material on a vertical surface to form a web of a wind turbine blade, the method comprising:

positioning a vertical surface in a mould for a wind turbine blade at a position corresponding to a position of a web of the blade;

spraying an adhesive on the vertical surface;

applying fibre material on the sprayed surface directly in the mould during layout of fibre material in the mould; and

injecting the fibre material on the vertical surface and in the mould with a resin during a resin injection process.

12. The method of claim 11 , further comprising:

applying the fibre material on the sprayed surface using an apparatus comprising a reel for supplying the fibre material and a plate for pressing the fibre material onto the sprayed surface.

13. The method according to claim 11 , further comprising selecting the adhesive to be of a composition which is desolved by the injected resin.
