Abstract

A manufacturing arrangement realized for manufacturing a rotor blade, including a pair of tracks arranged along the longitudinal sides of a blade mold; a first gantry assembly realized to span the track pair and to carry a first tool arrangement including at least a fiber distributor for distributing a fiber material into the blade mold; a second gantry assembly realized to span the track pair and to carry a second tool arrangement realized to carry a supply of fiber material and to provide the fiber material to the fiber distributor; and a control arrangement realized to effect a coordinated movement of the gantry assemblies along the track pair and to coordinate the operation of the second tool arrangement with the operation of the first tool arrangement is provided. A fiber mat magazine; a manufacturing line; a method of manufacturing a rotor blade; and a rotor blade, is also provided.

First claim

The invention claimed is:

1. A method of manufacturing a rotor blade, the method comprising:
(A) arranging a pair of tracks along longitudinal sides of a blade mold;
(B) arranging a first gantry assembly to span the pair of tracks and placing a first tool arrangement on the first gantry assembly, the first tool assembly comprising at least a fiber distributor for distributing a fiber material into the blade mold;
(C) arranging a second gantry assembly to span the pair of tracks and placing a second tool arrangement on the second gantry assembly, the second tool arrangement configured to carry a supply of fiber material and to provide the fiber material to the fiber distributor, the second gantry assembly including a magazine comprising a plurality of fiber matting reels of different sizes and thicknesses;
(D) operating a control arrangement to effect a coordinated movement of the first gantry assembly and the second gantry assembly along the pair of tracks and to coordinate an operation of the second tool arrangement with an operation of the first tool arrangement; and
(E) specifying a desired type and size of the fiber material according to a position of the first gantry assembly relative to the blade mold.

2. The method according to claim 1 , wherein the control arrangement is operated to control a winding unit to wind a specific length of fiber material to a tool attachment for the fiber distributor.

3. The method according to claim 2 , wherein the control arrangement is operated to control a lifting tool to lift a specific fiber matting reel from a fiber material supply to the winding unit.

4. The method according to claim 2 , wherein the control arrangement is operated to control the first gantry assembly and the second gantry assembly and/or the first tool arrangement and the second tool arrangement on a basis of a position relative to the blade mold.
