CE PROCEDE MET EN OEUVRE UN APPAREIL DE CHAUFFAGE SOUS PRESSION DE FLUIDE CALOPORTEUR, TEL QUE DECRIT AU BREVET PRINCIPAL, DANS LEQUEL LE PNEUMATIQUE EST MONTE SUR UN MOYEU ET SERRE ENTRE DEUX MEMBRANES ELASTIQUES PLAQUEES CONTRE LES FLANCS. LE PROCEDE EST CARACTERISE PAR UN MOYEN DE DRAINAGE CONNU EN SOI, RACCORDE A UNE SOURCE DE VIDE POUR DEGAZER L'ESPACE COMPRIS ENTRE LES MEMBRANES, LES FLANCS ET LES BORDS DE LA BANDE DE ROULEMENT. APPLICATION A LA FABRICATION, AU RECHAPAGE ET A LA REPARATION DES PNEUMATIQUES.THIS PROCESS APPLIES A HEATING APPARATUS UNDER HEAT TRANSFER FLUID, AS DESCRIBED IN THE MAIN PATENT, IN WHICH THE TIRE IS MOUNTED ON A HUB AND CLAMPED BETWEEN TWO ELASTIC MEMBRANES PLATED AGAINST THE SIDES. THE PROCESS IS CHARACTERIZED BY A MEANS OF DRAINAGE KNOWN IN ITSELF, CONNECTED TO A VACUUM SOURCE TO DEGAZE THE SPACE INCLUDED BETWEEN THE MEMBRANES, THE SIDES AND THE EDGES OF THE TREAD. APPLICATION TO THE MANUFACTURE, RETREADING AND REPAIR OF TIRES.

Description

Le brevet principal a pour objet un appareil de chauffage sous pressionThe main patent relates to a heater under pressure

pour vulcaniser au contact les unesdes autres, au moyen d'un fluide caloporteur, des parties de pneumatique en caoutchouc vulcanisable afin de les faire adhérer solidement entre elles, cet appareil comportant des membranes déformables sous l'action d'un fluide sous pression et étant remarquable par les caractéristiques suivantes: a) une cuve circulaire ( 1) composée d'un fond ( 2) et d'un couvercle circulaire ( 3) articulé sur ce fond, est supportée dans un bâti; b) un moyeu cylindrique ( 4) formant jante de montage du pneumatique à traiter est solidaire du fond ( 2) de la cuve, concentrique à celui-ci et comporte dans son pourtour des ouvertures ( 4 ') de circulation de gaz'; c) entre le pourtour extérieur du moyeu ( 4) et le pourtour ( 2 ') du fond ( 2) de la cuve s'étend une première membrane souple ( 6) en forme de couronne, à distance du fond de la cuve et, dans son ensemble, parallèle à ce fond; d) une deuxième membrane souple ( 6 ') en forme de couronne s'étend, à distance axiale de la première membrane ( 6) et de la face intérieure du couvercle ( 3) et, dans son ensemble, parallèlement à cette dernière, entre le pourtour ( 31) du couvercle et un support annulaire ( 3 ") solidaire de la face intérieure ( 3 ') du couvercle ( 3), coaxial au moyeu ( 4) et formant un rebord de jante, la distance entre les deux membranes ( 6, 6 ') définissant dans le sens axial une enceinte de réception du pneumatique (P) à chauffer; e) l'espace annulaire ( 10) compris entre le fond ( 2) de la cuve ( 1), la première membrane ( 6) et le moyeu ( 4), et l'espace annulaire ( 10 ') compris entre le couvercle ( 3), 2 - la deuxième membrane ( 6 ') et le support annulaire ( 3 ") formant rebord de jante, sont reliés à une source de fluide sous pression ( 10 A, 10 B); f) un ventilateur ( 8) et une résistance électrique de chauffage ( 9) sont disposés dans le moyeu ( 4), coaxialement à ce dernier; g) un ventilateur ( 13) est disposé au sommet de la cuve ( 1), entre le fond ( 2) et le couvercle ( 3) de celle-ci, à mi-distance entre les deux membranes ( 6, 6 '); h) une résistance électrique de chauffage ( 14) est disposée le long du pourtour ( 1 ') de la cuve ( 1), à l'intérieur de celle-ci, entre les deux membranes ( 6, 6 '); i) lorsqu'un pneumatique (P) est en place sur le moyeu ( 4), dans l'enceinte de réception selon d), il subdivise cette enceinte en un compartiment annulaire ( 11) compris entre le sommet (Ps) de ce pneumatique, les deux membranes souples ( 6, 6 ') et le pourtour ( 1 ') de 11 cuve ( 1) et en un compartiment central ( 12) situé radialement à l'intérieur du compartiment annulaire ( 11) et délimité par l'intérieur du pneumatique et le moyeu ( 4), chacun de ces deux compartiments étant relié indépendamment de l'autre à une  in order to vulcanize vulcanizable rubber tire parts in contact with one another by means of a heat-transfer fluid so as to adhere them firmly together, this apparatus comprising membranes that are deformable under the action of a fluid under pressure and being remarkable by the following features: a) a circular tank (1) composed of a bottom (2) and a circular cover (3) articulated on this bottom, is supported in a frame; b) a cylindrical hub (4) forming a mounting rim of the tire to be treated is integral with the bottom (2) of the tank, concentric thereto and has in its periphery openings (4 ') for gas circulation; c) between the outer periphery of the hub (4) and the periphery (2 ') of the bottom (2) of the tank extends a first flexible membrane (6) in the form of a ring, away from the bottom of the tank and, as a whole, parallel to this background; d) a second ring-shaped flexible membrane (6 ') extends axially from the first membrane (6) and the inner face of the lid (3) and, as a whole, parallel to the latter, between the circumference (31) of the cover and an annular support (3 ") integral with the inner face (3 ') of the cover (3), coaxial with the hub (4) and forming a rim flange, the distance between the two membranes ( 6, 6 ') defining in the axial direction a receiving enclosure of the tire (P) to be heated, e) the annular space (10) between the bottom (2) of the vessel (1), the first membrane (6) ) and the hub (4), and the annular space (10 ') between the cover (3), 2 - the second diaphragm (6') and the annular support (3 ") forming a rim flange, are connected to a source of fluid under pressure (10 A, 10 B); f) a fan (8) and an electric heating resistor (9) are arranged in the hub (4), coaxially with the hub (4); g) a fan (13) is disposed at the top of the tank (1), between the bottom (2) and the lid (3) thereof, midway between the two membranes (6, 6 '); h) an electrical heating resistor (14) is arranged along the periphery (1 ') of the tank (1), inside thereof, between the two membranes (6, 6'); i) when a tire (P) is in place on the hub (4), in the receiving chamber according to d), it subdivides the enclosure into an annular compartment (11) between the apex (Ps) of this tire , the two flexible membranes (6, 6 ') and the periphery (1') of the tank (1) and in a central compartment (12) located radially inside the annular compartment (11) and delimited by the interior of the tire and the hub (4), each of these two compartments being connected independently of one another to a

source de fluide sous pression ( 11 A, 12 A).  source of fluid under pressure (11 A, 12 A).
