Abstract: A method of compression moulding an article from rubber moulding material incorporating hollow inserts avoids damage to the inserts. Where compression moulding takes place in an enclosed mould at an elevated pressure, the pressure can distort and damage the hollow inserts especially if they are of plastics. In order to avoid such distortion and damage, the method compresses during moulding creating a pressure in a cavity of the insert which substantially balances the pressure exerted on the exterior of the insert by the rubber moulding material in the mould. The pressure in the cavity is preferably produced by introducing some rubber moulding material into the cavity of the insert. This material becomes pressurised during moulding and supports the interior of the insert.
