Abstract
A mould for moulding braking bands with ventilation ducts with the use of composite material and, in particular, of C/SiC ceramic material, comprises two half-moulds with respective impression surfaces which face one another and lie perpendicular to an axis of symmetry and which, together with outer and inner cylindrical walls, define a moulding cavity in the shape of the braking band to be moulded. The mould also has pin elements which have the shape of the ventilation ducts and which can be transferred by secondary actuating means from a rest position to a working position and vice versa, the pin elements being outside the moulding cavity in the rest position and the pin elements being inserted in the moulding cavity in the working position.
