  APPAREIL POUR LA RECONSTRUCTION DES BANDAGES PNEUMATIQUES POUR 
AUTOMOBILES, PAR CHAUFFAGE SEC A FEU DIRECT. 



   On connaît plusieurs appareils pour la reconstruction des surfaces de roulement des bandages pneumatiques pour au- tomobiles, dans lesquels le réchauffage nécessaire est ob- tenu par circulation de vapeur dans les moules, qui en con-   séquence,   doivent être creux. 



   Ces appareils, tout en donnant des résultats satis- faisants, sont très complexes et coûteux et demandent une installation spéciale de chaudières pour la production de la Vapeur nécessaire au réchauffement. 

 <Desc/Clms Page number 2> 

 



   La présente invention a pour objet un appareil de grande simplicité, qui ne demande aucune installation acces- soire, parce que le réchauffage du bandage à reconstruite est obtenue par feu direct, c-à-d. sans l'intermédiaire de la vapeur. 



   Le dessin annexé représente à titre d'exemple et sché- 
 EMI2.1 
 magiquement un mode d'exécution dudit appareil, suivant 1 ia. -   vention   et précisément: 
Fig.1 montre une vue latérale partie en coupe, et   Fig.2   montre une coupe transversale. 



   Comme on voit au dessin, l'appareil comprend essen- tiellement une chambre 1 ouverte en bas, dont les parois   la-   térales 2 sont pourvues de trous de sortie 3, et dans laquel- le on peut introduire des brûleurs d'un type quelconque, ou encore, allimer du charbon ou autre combustible, de manière à réchauffer opportunément le plafond 4 de ladite chambre qui constitue le moule pour le bandage porté sur elle et qui est indiqué schématiquement au dessin en 5. 



   Une autre caractéristique de l'invention est   l'enploi   de bandes en acier, aluminium ou autre métal approprié comportant estampés en relief ou en creux, des dessins, écritures ou toute autre   impression   que l'on doit reproduire sur la surface du bandage. 



   Ces bandes métalliques sont simplement appuyées sur le fond de la/gorge du moule de manière   à   pouvoir être faci- lement substituées afin de varier le type d'impression à reproduire. 



   Comme on voit l'appareil formant l'objet de l'invention, est d'une   très   grande simplicité et apte à utiliser tout gen- re de combustible. Le rendement de l'appareil est supérieur aux appareils dans lesquels le réchauffer est   obtenu   par l'intermédiaire de la   vapeur.   



   La forme et les dimensions de l'appareil susdit pour 

 <Desc/Clms Page number 3> 

 la reconstruction des bandages à feu direct, peuvent varier suivant nécessité sans sortir du cadre de   l'invention.-

  APPARATUS FOR THE RECONSTRUCTION OF PNEUMATIC BANDAGES FOR
AUTOMOBILES, BY DIRECT FIRE DRY HEATING.



   Several apparatuses are known for reconstructing the rolling surfaces of pneumatic tires for automobiles, in which the necessary heating is obtained by circulation of steam in the molds, which therefore must be hollow.



   These devices, while giving satisfactory results, are very complex and expensive and require a special installation of boilers for the production of the Steam necessary for heating.

 <Desc / Clms Page number 2>

 



   The object of the present invention is an apparatus of great simplicity, which does not require any accessory installation, because the reheating of the tire to be reconstructed is obtained by direct fire, that is to say. without the intermediary of steam.



   The accompanying drawing shows by way of example and diagram
 EMI2.1
 magically an embodiment of said apparatus, according to 1 ia. - vention and precisely:
Fig.1 shows a side view partly in section, and Fig.2 shows a cross section.



   As can be seen in the drawing, the apparatus essentially comprises a chamber 1 open at the bottom, the side walls 2 of which are provided with outlet holes 3, and into which it is possible to introduce burners of any type. , or again, ignite coal or other fuel, so as to appropriately heat the ceiling 4 of said chamber which constitutes the mold for the bandage carried on it and which is shown schematically in the drawing at 5.



   Another feature of the invention is the use of strips of steel, aluminum or other suitable metal comprising embossed or debossed, drawings, writings or any other impression which is to be reproduced on the surface of the tire.



   These metal bands are simply pressed against the bottom of the mold groove so that they can be easily substituted to vary the type of print to be reproduced.



   As can be seen the apparatus forming the object of the invention is very simple and capable of using any type of fuel. The efficiency of the appliance is superior to appliances in which heating is obtained by means of steam.



   The shape and dimensions of the above device for

 <Desc / Clms Page number 3>

 the reconstruction of direct fire bandages, can vary according to need without departing from the scope of the invention.
 EMI3.1
 R E v E N D I C A T I 0 N S.



   1) - Apparatus for the reconstruction of pneumatic tires for automobiles, characterized in that the necessary heating is obtained dry by means of a direct fire acting inside a chamber, the ceiling of which is shaped so as to constitute the mold for the bandage and is warmed directly by the said internal fire.
