The invention relates to a method for the production of a tyre tread, said tread comprising a plurality of raised elements (20), each raised element including a contact surface intended to make contact with the ground during the rotation of the tyre and side surfaces connected to said contact surface. The production method comprises the following steps in which: a raw tyre blank (11) is prepared; a cover layer (9) is placed on all or part of an outer surface of the raw blank; the raw blank (11) is positioned in a mould, said mould comprising a blade (5); the blade moulds a side surface of a raised element (20); and the raw blank is cured in order to obtain the tyre. The production method also comprises the following steps in which: the cover layer (9) is cut by cutting means belonging to the mould; and, during the moulding of the side surface of the raised element by the blade, a cut-out portion of the cover layer is driven by the blade into the raw blank such that side surface of the raised element is partially or totally covered by said cut-out portion. |
