    "Perfectionnements   aux tubes." 
La présente invention concerne un nouveau tube ainsi que le procédé de fabrication de celui-ci. 



   Il existe un grand nombre de petits tubes qui sont utilisés dans. les automobiles et autres machines et qui sont faits d'une matière flexible ductile telle que le cuivre. Ces tubes sont utilises   en   grand dans les au-   tomobiles   pour conduire le combustible liquide du réser- voir à essence au réservoir à. vide et de   là   au carbura- teur, et aussi comme tubes de radiateurs. 



   Le but de la présente invention est de fournir.-. un tube de ce genre d'un modèle nouveau et d'employer un nouveau procédé pour fabriquer ce tube, dans le but de

 rendre la fabrication plus économique. Il doit toutefois être bien entendu que les revendications ci-dessous, por- tant sur le produit et sur le procédé, ne sont en aucune façon limitées à des tubes destinés aux applications indiquées en particulier. ces dernières sont signalées purement   à.   titre   d' exemples.

 ple, en vue d'être neto#e. Elle est ensuite recouverue d'étain ou enduite de soudure sur les moitiés non corres- pondantes de ses faces opposées comme le montrent les figs. 



   6 et   9.   Cet étamage peut être exécuté d'une manière ap-   proprié   quelconque, par exemple en' faisant passer la ban- de en-dessous et au-dessus de bras creux x percés de trous, reliés à, des creusets à soudure 1 qui sont maintenus chauds par les brûleurs z. La soudure ou étain est .répartie uni- formément sur le ruban de métal par des rouleaux brosseurs 1   et-2.   



   La bande passe alors entre le rouleau supérieur   ± et   le rouleau inférieur c, qui impriment dans la bande un repli ou épaulement d. Ce repli se trouve d'un côté de l'axe de la bande, de sorte que l'un des côtés de'celle- ci est plus large que l'autre de manière à pouvoir s'en- rouler sur le coté le plus étroit. De ces rouleaux, la bande passe aux rouleaux je et f qui servent à la recour- ber de la manière indiquée aux figs. 3 et 8.

   La bande passe ensuite sur le mandrin g, comme le montrent les figs.4 et 8, et les rouleaux presseurs h, h disposés horizontalement servent à produire par pression l'enrou-   lement   de la bande, comme le montre la fig.   5..La   tête du mandrin est placée dans la matrice chauffante   etcal.1-     breuse   i, qui est munie d'une bobine de chauffage élec- trique , ou d'un autre élément chauffant approprié. Lors- que la matière est attirée dans cette matrice à calibrer, elle est étirée du diamètre représenté à la fig. 3 au dia-   metre   final représenté à la fig. 7..

   Ceci provoque un en- roulement complet sur tout l'arc de 360  (sauf l'épais-   @   

 <Desc/Clms Page number 4> 

 seur du repli) et amené les deux bords de la bande jusque contre le repli d. Cette .matrice soumet nécessairement les deux couches qui se recouvrent à une pression considéra- ble et ramollit en même temps l'étain ou soudure de miniè- re à souder les deux couches ensemble et à produire un tu- be absolument étanche. Il va de soi que des rouleaux pour- raient être employés à la place de la motrice chauffante et   calibreuse.   On   employera.   naturellement pour chaque couche une bande ayant une épaisseur moindre que celle que doit ordinairement avoir la matière dans le tube final.

   On obtient ainsi un tube étanche aux liquides et à l'air, qui peut être fabriqué à bon marché en longueurs continues. 



   Le terme "soudure"est employé,dans les revendi- cations, dans le sens large d'une   matière' métallique   quel- conque appropriée destinée à assembler des surfaces appro- priées. 



   -;- REVENDICATIONS

    "Tube improvements."
The present invention relates to a novel tube as well as to the method of manufacturing the same.



   There are a large number of small tubes that are used in. automobiles and other machinery and which are made of a flexible ductile material such as copper. These tubes are widely used in automobiles to conduct liquid fuel from the gasoline tank to the tank. vacuum and from there to the carburettor, and also as radiator tubes.



   The aim of the present invention is to provide. a tube of this kind of a new model and to employ a new process to manufacture this tube, in order to

 make manufacturing more economical. It should be understood, however, that the following product and process claims are in no way limited to tubes intended for the particular applications indicated. these are reported purely to. as examples.

   The strip coming from the reserve is first sent to an acid bath, hydrochloric acid, for example.

 ple, in order to be neto # e. It is then covered with tin or coated with solder on the non-corresponding halves of its opposite faces as shown in figs.



   6 and 9. This tinning may be carried out in any suitable manner, for example by passing the strip under and over hollow arms x drilled with holes, connected to welding crucibles. 1 which are kept hot by the burners z. The solder or tin is distributed evenly over the metal strip by brush rollers 1 and-2.



   The web then passes between the upper roll ± and the lower roll c, which imprint a fold or shoulder d in the web. This fold is on one side of the axis of the strip, so that one side of the strip is wider than the other so that it can be rolled up on the longer side. narrow. From these rollers, the strip passes to rollers i and f which serve to bend it in the manner indicated in figs. 3 and 8.

   The strip then passes over the mandrel g, as shown in figs. 4 and 8, and the pressure rollers h, h arranged horizontally serve to produce by pressure the winding of the web, as shown in fig. 5. The head of the mandrel is placed in the heating die and machine 1, which is provided with an electric heating coil, or other suitable heating element. When the material is drawn into this die to be sized, it is stretched to the diameter shown in fig. 3 to the final diameter shown in FIG. 7 ..

   This causes a full wrap over the entire arc of 360 (except the thick- @

 <Desc / Clms Page number 4>

 sor of the fold) and bring the two edges of the strip up to the fold d. This matrix necessarily subjects the two overlapping layers to considerable pressure and at the same time softens the tin or mineral solder by soldering the two layers together and producing an absolutely sealed tube. It goes without saying that rollers could be used in place of the heating and sizing motor. We will use. naturally for each layer a strip having a thickness less than that which must ordinarily have the material in the final tube.

   This results in a liquid and airtight tube which can be inexpensively manufactured in continuous lengths.



   The term "weld" is used in the claims in the broad sense of any suitable metallic material for joining suitable surfaces.
