Abstract
A method of manufacturing a body comprising the steps of forming a single strip of material with at least one plain region and at least one region of protrusions, such as corrugations, bumps or ridges. The single strip of material is then laid on itself in a manner so as to provide two or more layers of the material and locate a plain region of one layer alongside a region of protrusions of an adjacent layer. The laying step may be accomplished by winding the strip into a coil.
