## Abstract

A method for applying fibre material on a vertical surface is provided. The method has the following steps: spraying an adhesive on the vertical surface; applying the fibre material on the sprayed surface; 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 layers of fibre material with a resin.

## Claims

### Claim 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.

### Claim 2 (depends on 1)

The method according to claim 1, wherein
the fibre material is unrolled from a reel.

### Claim 3 (depends on 1)

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.

### Claim 4 (depends on 1)

The method according to claim 1, wherein
a fibre material in the form of a mat or a fabric is used.

### Claim 5 (depends on 1)

The method according to claim 1, wherein
a vertical surface is used which is made of wood or foam.

### Claim 6 (depends on 1)

The method according to claim 1, wherein
fibre material is applied on both sides of the vertical surface.

### Claim 7 (depends on 1)

The method according to claim 1, wherein
the resin is injected in a vacuum assisted resin transfer molding (VARTM) process.

### Claim 8 (depends on 1)

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.

### Claim 9 (depends on 8)

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.

### Claim 10 (depends on 1)

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

### Claim 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.

### Claim 12 (depends on 11)

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.

### Claim 13 (depends on 11)

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