Abstract: A method for manufacturing a wind turbine blade, comprising the steps of: • - providing one or more individual pultrusions (60) including a first tapering end (63) with a tapering end face terminating in a taper tip (64), and • - arranging the one or more pultrusions in one layer or more stacked layers including at least a bottom layer on a first assembly surface at a first assembly station to provide a pultrusion arrangement extending in a longitudinal direction between a pultrusion root end and a pultrusion tip end, wherein the first tapering end of the one or more pultrusions form the pultrusion root end (52) or the pultrusion tip end (53) of the pultrusion arrangement (51).

Abstract: A method of manufacturing a spar cap (44, 46) for a wind turbine blade part, comprise the steps of: • - providing a plurality of precured elongated fibre reinforced resin elements (50) • - stacking the plurality of fibre reinforced elements (50), an interlayer (57) of an elongated non-cured fibre material being arranged between successive fibre reinforced elements (50), thereby forming a stack (58) of precured fibre reinforced elements • - moving the stack (58) of fibre reinforced elements to a spar cap mould (66) comprising a mould bottom and mould side walls, • - arranging the stack of fibre reinforced elements in the cavity of the spar cap mould (66) • - infusing resin into the stack of fibre reinforced elements in the mould • - allow the resin to cure and demould the stack (80).

Abstract: A method of manufacturing a shell of a wind turbine blade (28) is disclosed. The method of manufacturing includes laying one or more layers of fiber on a surface of mould to form the shell. A spar element (60a) is positioned at a pre-defined position on the one or more layers of fiber, and a vacuum bag (100) is positioned or covered around the one or more layers of fiber and the spar element (60a). The method further includes step of infusion of resin through the one or more layers of fiber and the spar element. The resin is subsequently allowed to cure to obtain the shell (30a, 30b) of the wind turbine blade. The spar element is thus adhered to the shell through resin infusion process.

Abstract: The present invention relates to a mechanism for joining an elongated member and a receiving portion. The mechanism includes a locking pin, which is configured to connect the elongated member and the receiving portion. At least one first aperture is defined in one of the elongated member and the receiving portion and a plurality of second apertures is defined in other of the elongated member and the receiving portion. The at least one first aperture is selectively aligned with one of the plurality of second apertures, and the locking pin is configured to engage the aligned apertures to connect the elongated member and the receiving portion in different slidable lengths.
