Abstract
A mould element (18) intended to be attached in a mould (10) for vulcanizing tires, the mould element (18) having the form of a skin with a thickness (E) comprised between 0.25 and 6 mm and comprising a bearing surface (20) with, on the opposite side, a moulding surface (22) intended to form all or part of the external surface of the tire. The mould element comprises a pattern (30) comprising a plurality of recessed (19, 21, 112) or protruding (106, 107) elements, formed as integral parts of the mould element (18).
Claims10
A mould element adapted to be attached in a mould for vulcanizing a tire, the mould element having the form of a skin, the mould element comprising:
- a bearing surface on a first side of the mould element;
- and
- a moulding surface, on a second side of said mould element opposite the first side, the moulding surface being adapted to form all or part of the external surface of the said tire,
- the moulding surface comprising a pattern having a plurality of recessed or protruding elements formed as integral parts of said mould element, the pattern present on the mould making it possible to obtain a particular texture on a tire vulcanized using the mould,
- wherein the mould element comprises at least one of a bar or a sipe blade, and wherein the pattern is arranged on the at least one bar or sipe blade of the mould element, and
- wherein all or part of the pattern are substantially mutually parallel striations, the mutually parallel striations including square-wave shaped mutually parallel striations.
