Abstract: The tire 1 comprises a plurality of support elements 2 connected to an interconnection structure 3 to a tread 4, each support element being connected by a staple 7 to a wheel disk 6.

Abstract: A rigid core at least partially defining a manufacturing form for the internal surface of a tire, the core including a plurality of circumferentially adjacent fractions disposed side by side in contact with one another by their transverse faces, the transverse faces of at least one fraction converging radially at the exterior of the core, each of the fractions including a portion for attachment to a rim, the attachment portion being arranged at the radially internal end of each of the fractions, the attachment portion being produced essentially from a first material, the core further including a main portion which is integrally connected to the attachment portion, is produced essentially from a second material different from the first material and is integrally connected to the attachment portion, the manufacturing form being essentially defined by said main portion.

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.

Abstract: The tire mold includes a shell for the molding of the sidewalls, said shell including a laminated assembly formed of lamelliform elements directed substantially parallel to the axis, the molding surface for said sidewall being formed by the adjacent edges of the said lamelliform elements.

Abstract: The peripheral ring of a sector mold for tires is formed of an assembly of plates 1 resting against each other and stacked in such a manner as to push each other back. The ring therefore has a continuous tendency to increase in diameter. This tendency is resisted, for instance, by a conical hoop which simultaneously pushes all the plates 1 radially in molding direction.

Abstract: A tire mold including a pair of shells (2) for molding the side walls of tire and a ring or sectors (1) for molding the tread of the tire and in which each sector (1) of the mold includes an outer support (10) and an inner mold fitting (11). The contact of the sectors with each other and of the sectors on each side wall molding shell (2) takes place via segments (3) of small cross section, compressed elastically upon the closing of the mold, so as to assure complete tightness of the mold.
