In order to ensure excellent moulding of the rubber in the region of the markings appearing on the sidewall of a tyre, the shell 1 of the mould includes holes (perforations) 3 corresponding to the shape of the marking, into which is installed an insert 4 sliding in the hole 3. It is possible to adjust the relief of the marking. Venting is ensured by the clearance between the insert 4 and the hole 3. <IMAGE> |
