The burled structure in accordance with the invention has already been acquired with an even quality in prototype series, using a substrate interlace having the described geometry, by applying paste-like plasticised PVC from the range of surfacecoverage cited and then foaming and hardening. The burled structure materialises by itself during the foaming process. Although the burled structure is preferably formed directly by the foaming process, the possibility is not to be excluded that theburled structure is only then formed by an additional processing step, for example an embossing step. The embossing step, described above as being optional, could involve embossing the burled structure, i.e. in such a variant, the caterpillar ties with the burled structure and the individual burls of said burled structure are formed on their surface with another, finer embossing pattern. In another variant, the second-order burls and the embossing pattern would be formed in separate embossing steps.
