Abstract: The facility comprises a tire-building station that is configured to form an uncured tire on a core. A curing station is configured to cure the assembly formed by the core and the uncured tire so as to obtain a cured annular tire. An extraction station is configured to separate, after the curing operation, the cured tire from the core. The curing station has a first, heating, thermal source which presses against the exchange face of the core for the curing operation and is then dissociated from the core and remains in the curing station in order to leave the exchange face free again when the core and the cured tire are transferred to the extraction station so that a second, refrigerating, thermal source of the extraction station takes the place of the first thermal source in contact with the exchange face of the core so as to cool the core.

Abstract: The process includes a non-crosslinked self-sealing composition which is introduced into an extrusion means, the geometric and thermodynamic characteristics of which have been specially adapted. The speed and temperature conditions of the extrusion means are adjusted so that, at an application nozzle forming the outlet die of the extrusion means, the self-sealing composition is crosslinked. The application nozzle is brought close to the internal surface of the casing previously set in relative motion with respect to the application nozzle, and an extruded and crosslinked bead that has a given width and profile is deposited directly on the internal surface of the casing.

Abstract: A method produces a hardened galvanization of a continuously-running rolled steel strip. The strip is immersed in a coating tank containing a bath of a liquid metal mixture, e.g. zinc and aluminum, to be deposited on the strip, and permanently circulated between the coating tank and a preparation device. The temperature of the liquid mixture is deliberately lowered in order to reduce the iron solubility threshold and sufficiently high for initiating, in the preparation device, the fusion of at least one Zn—Al ingot in an amount necessary for compensating for the liquid mixture used for deposition on the strip. The device is implemented so that the circuit for circulating the liquid mixture is thermally optimized.

Abstract: An installation for the hardened galvanization of a continuously-moving rolled steel strip, includes a coating tank receiving a liquid metal mixture containing, for example, zinc and aluminum to be deposited on the strip which is immersed in the mixture. The liquid mixture is permanently circulated between the coating tank and a preparation device, in which the temperature of the liquid mixture is deliberately lowered in order to reduce an iron solubility threshold and is sufficiently high for initiating fusion of at least one ingot containing a zinc-aluminum Zn—Al alloy in a so-called fusion zone of the preparation device, in an amount necessary to compensate for the liquid mixture used for deposition on the strip. The installation includes a loop for circulating the liquid mixture that is thermally optimized.

Abstract: The invention concerns a method for adjusting the thickness of the welding bead of two bands (M1, M2) obtained by butt welding by means of a laser beam without using filler material. The bands are clamped in jaws (S1, S2), both cut edges (10, 20) being spaced apart by a reference distance (D?). Then the mobile jaw is moved along a travel (C). Said travel (C) differs from said reference distance (D?) by a preset play calculated in relation to the thickness of the bands, and while taking into account the degree of accuracy of the positioning and of the cut of said edges (10, 20). The preset play is counted as positive or negative, in order to obtain a final welding position such that it exists, between the edges (10, 20), an actual allowance, positive or negative, adapted to the thickness of the bends.
