Abstract

The device comprises two mould halves (3,4). The mould halves are connected to one another and are pivotable around a rotary axis (5). The mould halves have an inner contour corresponding to the required outer profile of the vanes and retention components. During at least the last part of the pivoting process for the mould halves from an extended position to one where they are brought together they retain the plate so that it does not slide or move relatively to the mould halves, whereby the plate is pressed against the inner contour of the mould halves.
