<p>The invention relates to a method of moulding a cornice from a gypsum based settable material. The method includes providing first and second elongate mould members (12 and 14) which are arranged to define an open-topped, open-ended mould cavity when connected to one another, and locating at each of the ends of the first elongate mould member (12) an end stop (28) which is designed to form a seal between the ends of the elongate mould members when the members are connected to one another. Three pairs of fibrous strands are then secured to the two end stops (28) to provide six lengths of strand which extend across the first mould member (12) from one end stop to the other. Thereafter, the second mould member (14) is connected to the first mould member (12) to define an open-topped mould cavity across which the six lengths of strand extend, and a gypsum based settable material is introduced into the mould cavity to form a cornice. Once the settable material has set, the second mould member (14) is separated from the first mould member (12), the end stops (28) are separated from the cornice, and the cornice is removed from the first mould member (12).</p> |
