Abstract
The method comprises the steps of: forming one or more sheets of material in a single sheet of material with at least one generally planar region and at least one region of first corrugations. Second corrugations which are smaller than the first corrugations are then superimposed on the, or each, generally planar region and the, or each, corrugated region. The generally planar region, or regions are then laid onto the region, or regions that are provided with the first corrugations.
