Abstract

The invention relates to a process for producing a mould core for the production of wind power plant rotor blades in one piece. According to the invention, the process comprises the following steps: providing a flexible hollow body, for example a film tube, inserting the hollow body between at least two mould parts, which are arranged relative to one another in such a manner that they form a negative mould of the rotor blade to be produced, filling the hollow body with bulk material before or after Insertion of the hollow body between the mould parts, and generating a negative pressure in the hollow body after it has been filled and inserted, in such a manner that the hollow body solidifies. The invention furthermore relates to a process for generating a negative pressure between mould parts and mould core.
