ABSTRACT:
The tire mold includes a peripheral ring split into two parts (G and D). The peripheral ring is laminated. It consists of a stack in the circumferential direction of a number of thin adjacent elements (1) made, for example, of metal sheets. The elements are of two different types: standard elements and intermediate elements, which follow on from one another circumferentially. The mold includes alignment means interacting with said intermediate elements in order to impose an orientation with respect to the radial direction on said intermediate elements. These means are, for example, grooves in which the intermediate elements are engaged.
