Lining Assembly on a Skin for a Tire Vulcanization Mould

1 . Lining assembly comprising:

a skin having first and second opposed surfaces, the first surface suitable to be in contact with a support block of a tire mould, the thickness of the skin being between 0.25 and 3 millimeters; and

a plurality of lining elements projecting from the second surface of the skin, the lining elements being suitable to form tread patterns on a portion of a radially external surface of a tire,

the skin and the lining elements being produced as one piece.

2 . Assembly according to claim 1 , produced by laser sintering.

3 . Assembly according to claim 1 , in which the shape of the first surface of the skin is complementary to that of a mould support block to which the lining assembly is intended to be attached.

4 . Assembly according to claim 1 , in which the second surface of the skin is shaped so as to partially define the shape of the tire while it is being molded.

5 . Process for manufacturing a lining assembly, comprising:

a skin having first and second opposed surfaces, the first surface suitable to be in contact with a support block of a tire mould, the thickness of the skin being between 0.25 and 3 millimeters; and

a plurality of lining elements projecting from the second surface of the skin, the lining elements suitable to form tread patterns on a portion of a radially external surface of a tire,

comprising producing the skin and the lining elements are produced as one piece.

6 . Process according to the preceding claim, in which the assembly is produced by laser sintering.
