Abstract
The sector mold (11) is designed so that, during the molding phase, the molding elements (10, 10a, 10b, 10c) are all equidistant due to devices (13) which assure an elastic repulsion between each other. Some of the elements glide circumferentially with respect to their sector (11) in the final closing phase. In this way, pinching of the rubber between sectors and the appearance of molding burrs are avoided.
