Abstract
The invention is a method for forming a gasket over an opening of a hollow form. The method comprises placing an unformed gasket (12) over a mould surface (14) having a shape in relief that is the shape to which the gasket (12) is to be formed. A hollow form (10) is placed onto the mould (13) so that the gasket (12) is held between the opening (11) of the hollow form (10) and the mould surface (14). Expanding foam (15) is located within the hollow form (10) so that the foam (15), as it expands, pushes against the gasket (12) to form it to the shape of the mould surface (14). This shape is retained upon setting of the foam. The invention greatly simplifies the manufacturing process of a hollow form (10) fitted with a gasket (12).
