Abstract

Expandable mould for producing plaster articles having >=1 surface provided with reliefs, comprises >=2 walls assembled from >=2 deformable but incompressible elements disposed between the lateral edges of the parallel walls so as to ensure a seal between the walls. Each element has a profile on its interior mould face which is enhanced under the effect of pressure during moulding and which is retracted on demoulding after releasing the pressure leaving a corresponding profile on the moulding. Provides good size accuracy while avoiding the high cost of high precision, wear-resistant moulds.
