Profiled sections 1, in particular extruded seals made of elastic material, are designed and produced economically such that they have absolute storage stability and low coefficients of friction and are suitable for a wide variety of uses. The profiled sections 1 are made of a non-lacquer-repelling material. After leaving the extruder 12 and before entering the fused salt bath 16 the profiled sections are coated with a lubricating lacquer 7 applied to the uncured surface 5. The lubricating lacquer 7 is then cured in the fused salt bath 16 without there being a need for a separate curing section or similar. This method not only evenly coats the profiled sections with lubricating lacquer 7 but also prevents the formation of air bubbles or the like, thereby yielding a consistently even coating 6.
Procedure for producing profiled sections, that can be further processed, out of elastic material, particularly profiled joints for the construction industry, which are extruded and then cured in fused salt at 170-330° C., and onto which the necessary data is printed as well as a coating is applied and then dried, characterized by the fact that the profiled section is produced out of non-lacquer-repellent material and coated with a lubricating lacquer applied to the uncured surface after leaving the extruder and before entering the fused salt bath.
