ABSTRACT:
A tire-vulcanizing mold including a profiled segment. In order to assure a safe gas discharge from the cavity formed in the tire-vulcanizing mold during the forming of the tire blanks, the invention provides that the profiled segment be divided along at least one interface into at least two partial profiled segments, that the interface extends substantially parallel to a plane of rotation in relationship to the tire mold, and that the interface cuts the areas of the tire-vulcanizing mold to be vented. Manufacture of the segments is done much that the profiled segment is first manufactured in one piece and is thereafter divided into the partial profiled segments by a cutting operation leaving behind a narrow cutting line.
