<p>A method of manufacturing a flexible, impact-resistant material includes the steps of providing a sheet of a closed-cell foam material and cutting the sheet into at least two tessellating patterns, preferably by a cutter. The tessellating patterns are then differentially moved relative to one another such that the surface of one of the tessellating patterns stands proud of the surface of the other tessellating patterns. A first, flexible layer of material is then bonded to the surface of the tessellating pattern standing proud of the rest. Preferably, a block arrangement is located in the cutter that causes the tessellating patterns to move relative to one another after the sheet of foam material has been cut.</p> |
