Abstract:
Molding element for molding and vulcanizing a tire tread, having a tread surface contacting the ground when rolling, having a molding surface to mold part of the tread surface and a blade of length and of height H to mold a sipe or a groove in the tread, having a rounded end extending along its length in a direction of extension X. The molding element has two cutting means to cut a cover layer applied to a green form of the tire, positioned on either side of the blade at a certain distance from this blade, each cutting means having a cutting edge extending in the direction of extension, making an acute angle α in a sectional drawing perpendicular to direction of extension X able to cut the cover layer, the distance between this cutting edge and the molding surface being lower than the height H of the blade.
