ABSTRACT:
A covering profile for structures is manufactured by pressing a non-swelling mixture of fibrous materials and thermosetting binding agent. The covering profile has an elongated body whose upper surface is provided with grooves extending parallel to the elongation of the body and being regularly spaced from each other. Associated to each groove in the upper surface are two countergrooves in the rear surface of the body. The method for manufacturing a so-shaped covering profile includes the prepressing in a prepressing tool having plane surfaces while the grooves and countergrooves are produced in the hot pressing.
