Abstract: A reinforced mould, including a mould body having in at least one end surface thereof a mould cavity which presents relatively sharp corners when seen in cross section, and in which the mould body has arranged along at least part of its axial length a pretensioned reinforcing means in the form of at least one winding of thin metallic strip material and is slotted generally axially along at least two of said corners to form separate body portions, said body portions being held in contiguous relationship solely by the pre-tensioning force exerted by the reinforcing means on said body.
