PROCESS AND APPARATUS FOR VULCANIZATION AND MOULDING OF VEHICLES TYRES

摘要

The present invention refers to an apparatus and process for moulding and vulcanization of vehicle tyres. The apparatus for moulding and vulcanization of vehicle tyres comprises a mould (1) for forming a moulding cavity (3) having a conformation corresponding to the outside conformation to be given to the vulcanized tyre and comprising a pair of shells (4) axially opposed and each having a working surface (5). The working surface (5) has an annular development and is predisposed to operate on the beads (6) and on the sidewalls (7) of a raw tyre (2) to be vulcanized. The working surface (5) of at least one of the shells (4) also has an annular groove (12) developing along its own annular development. A annular insert (13) is removably mounted in the annular groove (12) and has a moulding face (14) opposite the moulding cavity (3) whose moulding face (14) bears graphic marks (15) to imprint on the sidewall (7) of the tyre (2).
