Abstract: A tool for reducing vibrations in wind turbine blades at standstill includes an elongate sleeve formed of a net-like material for fitting over the blades, wherein the sleeve is formed with at least one protruding structure extending along at least a part of the length of the sleeve having an undulating form, and which is arranged so that when the sleeve is fitted on a blade the protruding structure or structures lie at the leading and/or trailing edge of the blade. A method for securing wind turbine blades against oscillations is also disclosed.

Abstract: A roll (16) of structural material for use in the manufacture of large composite structures such as wind turbine blades is described. The roll (16) comprises an elongate stack of structural layers (10) fastened together and wrapped around a reel (14). The reel (14) comprises a plurality of mutually spaced supports (50) about which the stack is folded into a rolled stack. Sections of the rolled stack between the supports are substantially unsupported by the reel and are held in a slack state in order to prevent wrinkles from forming in the rolled stack.
