A first inter-related product is provided in the form of a preformer apparatus 2 comprising one or more ground engaging supports 4, a hood 6, and a diaphragm frame 8 that is adapted to receive and hold a diaphragm, wherein the hood is movably mounted to the ground engaging supports between which it extends, and wherein the diaphragm frame is mounted to the hood from which it is independently movable. A second inter-related product is provided in the form of table which is adapted to support a forming tool and which is adapted for location in use generally below the hood. Preferably, the diaphragm frame is mounted to the hood via a plurality of shafts; downward motion of the hood lowers the diaphragm frame into place on the table, the weight of the diaphragm frame providing a seal around the table. The preformer apparatus is suitable for use with dry carbon fibre fabric, pre-preg and other woven materials and particularly, but not exclusively, for use in the manufacture of large scale composite items, for example, aircraft wing and fuselage components.
