Abstract
A molding element for equipping a mold for molding a rubber tread, composed of at least two molding parts provided with lateral walls and end walls joining the lateral walls, the lateral walls being intended to mold in the rubber tread main walls defining a cutout, the main walls being connected by at least one rubber connecting element. In the molding position, the molding parts of the molding element are arranged such that one wall of a molding part is in contact with at least one wall of another molding part, the geometries of the walls of the molding parts being functionally arranged to form at least one orifice permitting the passage of the rubber for molding a connecting element. At least one of the molding parts is mounted to be mobile relative to the molding part with which it defines at least one orifice, such that, under the action of the demolding forces, the mobile part is displaced relative to the other to create a passage sufficient to permit the molded connecting element(s) to pass and thus to permit demolding of the rubber tread in a single operation without breaking the connecting elements.
