Publication number: 20240075701Abstract: 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.Type: ApplicationFiled: October 21, 2021Publication date: March 7, 2024Applicant: Compagnie Generale Des Etablissements MichelinInventors: David BOUCHEREAU, Jean MECHIN, Francois ROUYET, Jean-Claude DELORME, Stephane BARJON

Patent number: 11602912Abstract: The method comprises steps during which, by making the cylindrical form rotate in a first circumferential direction, the ply is deposited until the front edge and performs a complete rotation. A point of penetration is marked on the ply on a cutting line, and a cutting blade that is driven in translation is made to penetrate between two wires placed on the cutting line at the point of penetration. The cylindrical form is made to rotate in an opposite second circumferential direction while displacing the cutting blade in a first transverse direction until the cutting blade is disposed at a predetermined and non-zero distance from a first selvedge. Without retracting the cutting blade from the wire gap, the cylindrical form is made to rotate in the first circumferential direction while displacing the cutting blade in an opposite second transverse direction until the cutting blade emerges at a second selvedge.Type: GrantFiled: December 12, 2018Date of Patent: March 14, 2023Assignee: Compagnie Generale des Etablissements MichelinInventors: Stéphane Barjon, Michel Gayton

Patent number: 9238859Abstract: 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.Type: GrantFiled: February 8, 2008Date of Patent: January 19, 2016Assignee: Primetals Technologies France SASInventors: Stephane Barjon, Arnaud D'Halluin, Benjamin Grenier

Patent number: 8305588Abstract: A measuring method and a device are adapted for the positioning of a wheel for mash seam resistance welding in the butt-joining of steel strips on continuous processing lines. A rotary roller which is fastened to a movable frame is positioned in a measuring position that is vertically below a reference wheel. The reference wheel is lowered vertically to come into contact and bear on the rotary roller. A distance between an index on a measuring arm of the frame and an articulated column is repeatedly measured during the continuous lowering movement of the roller. The distance is compared with a distance threshold for each of the repeated measurements until the wheel reaches a first operating position where the distance equals a predefined distance threshold factor. The first operating position is recorded as a reference point in a system for the vertical movement of the reference wheel.Type: GrantFiled: April 11, 2008Date of Patent: November 6, 2012Assignee: Siemens VAI Metals Technologies SASInventors: Stéphane Barjon, Hervé Thomasson

Patent number: 7820938Abstract: A method is provided for adjusting the thickness of the welding bead of two bands obtained by butt welding by means of a laser beam without using filler material. The bands are clamped in jaws, both cut edges being spaced apart by a reference distance. Then the mobile jaw is moved along a travel. Said travel differs from said reference distance by an offset 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. The offset is counted as positive or negative, in order to obtain a final welding position such that it exists, between the edges, an actual allowance, positive or negative, adapted to the thickness of the bands.Type: GrantFiled: May 10, 2005Date of Patent: October 26, 2010Assignee: Siemens VAI Metals Technologies SASInventors: Pascal Gobez, Stéphane Barjon

Publication number: 20050242071Abstract: 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.Type: ApplicationFiled: May 10, 2005Publication date: November 3, 2005Inventors: Pascal Gobez, Stephane Barjon
