    "Procédé de fabrication de bandages de roues. "   
Les procédés actuellement utilisés pour la fabrication de bandages de roues sont extrêmement fastidieux et coûteux. Un lingot normal, la plupart du temps octogonal, est d'abord forgé, pour lui donner à peu près la hauteur du bandage, puis perforé au mandrin, et enfin travaillé à la bigorne, Après un8réchauffage au four tournant, la couronne brute   de forge   est amenée aux laminoirs à bandages, qui lui donnent exactement le diamètre désiré, pois enfin refroidie lentement. En outre, on connaît encore des procédés permet- tant la fabrication de bandages de roues sans travail préala-

 lable de la bigorne, et en une seule chaude, en partant du lingot perforé. 



   Le procédé selon 1'invention constitue une importante simplification dans la fabrication de bandages. 



   D'après le présent procédé, les bandages sont amenés au profil voulu dans les trains de laminoirs normaux, puis coupés à la longueur nécessaire, taillés en biseau aux deux extrémités, après quoi les éléments rectili- gnes ainsi obtenue sont cintrés pour recevoir leur forme cir- culaire. Au point de fermeture existe par conséquent un joint, du fait que les deux surfaces de contact sont exactement parallèles. Ces deux surfaces de contact sont, finalement, assemblées à l'aide de la soudure par'rapprochement. 



   Le dessin annexé donne un exemple   schémati-   que de réalisation du procédé. Dans ce dessin : 
La figure 1 montre en coupe transversale le bandage terminé. 



   La figure 2 représente, en élévation, le même 'bandage, et montre en traits mixtes une phase de sa fa- brication. 



   Les deux extrémités de l'élément rectiligne a, obtenu par laminage normal, et qui présente déjà, en coupe transversale, le profil désiré, sont taillées selon un biseau c, dont l'obliquité est déterminée par la pratique. 



  L'élément rectiligne a est cintré jusqu'à former une couron- ne b, du diamètre voulu, qui présente au joint d deux sur- faces parallèles lesquelles seront assemblées à l'aide de la soudure par rapprochement.

    "Method of manufacturing wheel tires."
The methods currently used for the manufacture of wheel tires are extremely tedious and expensive. A normal ingot, most of the time octagonal, is first forged, to give it roughly the height of the bandage, then perforated with a mandrel, and finally worked with a bigorne. After heating in a rotary kiln, the rough forge crown is brought to the rolling mills, which give it exactly the desired diameter, peas finally cooled slowly. In addition, methods are still known which allow the manufacture of wheel tires without preliminary work.

 lable of the bigorne, and in a single hot one, starting from the perforated ingot.



   The process according to the invention constitutes an important simplification in the manufacture of bandages.



   According to the present process, the tires are brought to the desired profile in normal rolling mill trains, then cut to the required length, bevelled at both ends, after which the rectilinear elements thus obtained are bent to receive their shape. circular. At the point of closure there is therefore a seal, since the two contact surfaces are exactly parallel. These two contact surfaces are, finally, assembled using the butt weld.



   The accompanying drawing gives a schematic example of the process. In this drawing:
Figure 1 shows the finished bandage in cross section.



   FIG. 2 shows the same tire in elevation, and shows in phantom lines a phase of its manufacture.



   The two ends of the rectilinear element a, obtained by normal rolling, and which already has, in cross section, the desired profile, are cut according to a bevel c, the obliquity of which is determined by practice.



  The rectilinear element a is bent so as to form a crown b, of the desired diameter, which has at the joint d two parallel surfaces which will be assembled by means of the welding by approximation.
