Abstract
In a vulcanization and moulding apparatus for tyres and a method of manufacturing the same, the apparatus includes containment walls defining an inner surface delimiting a moulding cavity. The shape of the inner surface matches the final conformation to be given to the vulcanized tyre and includes a plurality of lamellae. Each lamella comprises at least one lug inserted in a respective seat formed in the inner surface and opening on the inner surface itself. The lug and the respective seat, along an insertion direction of the lamella into the seat, are at least partly misaligned relative to the work portion. The work portion of the lamella further comprises at least one abutment surface bearing against the inner surface of the moulding cavity. The seat is closed with an addition material by laser or tungsten inert gas welding, so as to lock the lamella in the moulding apparatus.
