Abstract
A method for laying a sheet of material having a sticky texture on to a surface comprises applying pressure by way of a flexible diaphragm to force the sheet of material on to the surface and adjusting the diaphragm so that its surface assumes a varying curved convex shape whereby the diaphragm is peeled gradually from the surface of the sheet of material inwardly from an edge region. The invention is described with particular reference to the laying of sheets of pre impregnated fibre-reinforced material in a mould tool in the automated manufacture of a helicopter rotor blade and several embodiments are disclosed.
