3 of 18

Designing a running mould profile The profile is the desired shape of the finished product. This fixed to the stock of the running mould. The profile will contain different shape members in its design which forms the detail of the finished mould. Moulding members are Roman and Grecian in origin, which form the outline pattern of the mould.

In-situ cornice moulding members Cavetto This is a curved shaped member very similar to a coving hence the name cavetto. Drawn with a compass to form an inward curved shape: a quarter segment of a full circle.



5 of 18

In-situ cornice moulding members Ovolo This moulding member is the opposite of a Cavetto. This time the curve projects out: a quarter segment of a full circle.



6 of 18

In-situ cornice moulding members Cyma Recta This shape curves inwards at the top and outwards at the bottom. This is formed with a compass from two points that meet at the outer curves in the centre. This shape is made up of the cavetto and ovolo moulding.



7 of 18

In-situ cornice moulding members Cyma Reversa This time the top half projects outwards and the bottom half curves inwards to form the shape of the member.



8 of 18

In-situ cornice moulding members Fillet This member is drawn as a right angle. This member is used to separate different types of curved members.



9 of 18

In-situ cornice moulding members Torus This moulding member projects outwards and is drawn as a semi-circle segment. This type of member is popular with skirting or panel moulding design.



10 of 18

In-situ cornice moulding members Scotia This is a popular member in a cornice mould design, which divides the projection and depth of the moulding members. An inward curved shape which is drawn from two centre points. Using this type of member in the design will reduce the weight of the mould and is incorporated where the ceiling and wall line meet.
