Method and apparatus for manufacturing a part of a wind turbine blade
First Claim
1. A method for manufacturing a part of a wind turbine blade, the part having a longitudinal length, the method comprising the steps of:
- pultruding composite material through at least one die to form a pultruded composite material having a general cross-sectional profile; and
performing an in-line shaping of the pultruded composite material to adjust the general cross-sectional profile of the pultruded composite material along at least a portion of a longitudinal length of the pultruded composite material to form the part of a wind turbine blade,wherein the step of performing an in-line shaping comprises adjusting a pultrusion path for the pultruded composite material to provide the pultruded composite material with a variable cross-sectional profile which varies along the at least a portion of the longitudinal length of the pultruded composite material,wherein the part of the wind turbine blade comprises a web foot for a wind turbine blade shear web.

Abstract
A method for manufacturing a part for a wind turbine blade, and in particular a part of a shear web for a wind turbine blade, is described. The method comprises pultruding the part, wherein an in-line shaping of the part is performed, to provide a part having a cross-sectional profile which varies in the longitudinal length of the part. Providing a shear web having a portion which varies in cross-sectional profile results in production of a wind turbine blade part which can be accurately controlled to have precise geometrical profile corresponding to a desired blade profile, with minimal waste of materials.
