Method of manufacturing a tire tread

A method of manufacturing a tire tread, the tread comprising a plurality of raised elements, each raised element comprising a contact face adapted to come into contact with a ground when the tire is rolling along and lateral faces connected to this contact face, the method comprising:

• preparing a green form of the tire;
• laying a cover layer over all or part of an external surface of the green tire;
• laying the green tire in a mold;
• with the mold comprising one blade, using the one blade to mold one of the lateral faces of one of the raised elements;
• vulcanizing the green tire in order to obtain the tire;
• cutting the cover layer using cutting means belonging to the mold;
• during the molding of the one lateral face of the one raised element by the one blade, driving with the one blade a cut part of the cover layer into the green tire so that the one lateral face of the one raised element are partially or fully covered by this cut part,
• wherein the cutting means contacts the cover layer of the green tire before the at least one blade comes in contact with the cover layer of the green tire;
• and wherein the cutting means includes two cutting edges disposed on opposite sides of said blade and during the step of driving with the one blade, a cut end of the cover layer created by one of the cutting edges moves away from the one cutting edge as the cover layer slips over the external surface of the green tire due to the driving of the cover layer into the green tire by the blade.
