Abstract: Apparatus for fabricating a reinforcement structure for a tire, the said reinforcement structure comprising threads disposed substantially parallel to each other, the said apparatus being intended to be used in cooperation with a substantially toroidal form (1) on which the said reinforcement structure is progressively constructed by depositing arches of the said thread side by side along a desired trajectory for the said thread on the surface of the said form, the said apparatus comprising an assembler (5) comprising an entry for receiving the threads (2), a rubber-coating chamber (50), a volumetric pump for delivering a rubber composition inside the rubber-coating chamber, an outlet orifice for a strip (20) comprising the threads joined by the said composition, a device (4) for depositing the said strip comprising a reference framework with respect to which it is possible to install the said form at a known position.

Abstract: A process of depositing at least one uncured colored rubber mix forming a contrasting motif on an outer surface of a tire includes preparing a blank of the uncured tire to be moulded, including all the constituents except for the colored rubber mix(es), depositing the colored rubber(s) in at least one cavity formed on a removable insert, each cavity having the general form of the motif to be moulded and having a total volume V2, the total volume of non-vulcanized colored rubber V1 placed in each cavity being less than the volume V0, mounting the insert in a suitable housing provided on the moulding surface of the mould for the tire, engaging the tire blank within the mould, and moulding and vulcanizing the tire.
