The invention relates to a moulding element of a mould for moulding and vulcanizing a tyre tread, this tread comprising a tread surface intended to come into contact with the ground when the said tyre is running. The moulding element (1) comprises a rib (5) intend to mould a groove in the tyre tread, this rib (5) comprising a rounded end. Indeed, the moulding element comprises two cutting means positioned on either side of the rib (5) at a certain distance from this rib, each cutting means (7) comprises a cutting edge (8), this cutting edge making an acute angle. The moulding element (1) comprises a plurality of lamellas (9) positioned between the rib (5) and the cutting means (7), the lamellas being shallower than the ribs (5). The rib (5) having a direction of extension X and each lamella (9) having a direction of extension Y, the direction of extension Y of the lamella makes an angle α with the direction of extension X of the rib, this angle α being less than 20°. |
