ABSTRACT:
A process for shaping a body with elongate structures on its surface, bodies produced using the process, and to apparatuses having these bodies are provided. For this purpose, a preform is provided, at the surface, with structures which are elongate along one direction, the preform is heated at least in one region and the preform is drawn in the heated state until at least part of the preform has adopted a cross section which substantially corresponds to the desired cross-sectional shape or final cross-sectional shape. The preform is heated by means of radiation which has a spectral distribution which is such that at most half of the radiation power is absorbed during a single pass through the material.
