  • Patent number: 11858227
    Abstract: A method of manufacturing a wind turbine blade shell part is described. Fibre mats and a root end insert are laid up in a mould part in a layup procedure by use of an automated layup system. The fibre mats are laid up by use of a buffer so that the fibre mats may continuously be laid up on the mould surface, also during a cutting procedure. The root end insert is prepared in advance and mounted on a mounting plate. The root end insert is lowered onto the mould by use of the mounting plate and a lowering mechanism. After the wind turbine blade shell has been moulded, the mounting plate is removed.

  • Patent number: 8951034
    Abstract: A modular mold system for manufacturing a shell part of an oblong composite structure having a longitudinal direction from a fiber reinforced matrix material. The modular mould system includes a number of mold sections, which are adapted to being assembled to an assembled mold part. The number of mold sections includes a first mold section having a first molding surface with a contour that defines a surface of a first longitudinal part of the shell part and a first end section; and a second mold section having a second molding surface with a contour that defines a surface of a second longitudinal part of the shell part and a second end section; which, when the modular mold system is assembled to the assembled mold, the second end section of the second mold section abuts the first end section of the first mold section.
