1. A lining assembly, produced by laser sintering, comprising:

a plurality of lining elements capable of attachment to a support block of a mould for a tire, the lining elements capable of forming tread blocks of part of a tread band of a tire,

at least one sacrificial connecting element joining the lining elements together, wherein the lining elements and the connecting element have been produced as a single piece; and

at least one rupture initiator where the at least one sacrificial connecting element joins one or more of the lining elements.

2. The lining assembly according to claim 1 , wherein the rupture initiator comprises a local reduction in the thickness of the connecting element.

3. A segment of a tire vulcanizing mould, comprising a support block and the lining assembly according to claim 1 , attached to the support block.

4. A tire vulcanizing mould, comprising two lateral shells each having an edge, and a plurality of segments according to claim 3 , the segments being circumferentially distributed around the edge of the shells.

5. A method of obtaining a tire vulcanizing mould, comprising:

manufacturing a lining assembly according to claim 1 ,

attaching the lining assembly to a support block,

eliminating the sacrificial element.

6. The method according to claim 5 , further comprising producing the lining assembly by laser sintering.

7. The method according to claim 5 , wherein the attaching of the lining assembly to the support block comprises bonding, screwing or clipping.
