Abstract
A planar, biaxially heat-shrinkable, plastics mesh layer is fixed to a planar, relatively non-heat-shrinkable plastics mesh layer at zones which are spaced apart on a generally square grid, and the structure so formed is heated to cause the shrink layer to shrink biaxially and thereby cause the non-shrink layer to assume a cuspated configuration. The structure can be shipped as a semi-finished product after fixing the layers together and before heating, thereby reducing bulk and hence shipping costs.
