Description

       

  "Dispositif pour vernir extérieurement les joints longitudinaux de viroles de tôle, notamment pour boites à conserves**.

  
Quand on soude les bords superposés d'une virole de boite à conserves ou récipient analogue, qui. servent à former un joint longitudinal, on obtient toujours par suite de l'accumulation de chaleur une virole dont le joint longitudi-

  
 <EMI ID=1.1> 

  
c'est représenté de manière exagérée sur la Fig. 1 du dessin annexé. Le joint longitudinal soudé de ces viroles, qui sont généralement faites d'une bande de tôle non-étamée, vernie à l'exclusion des bords, doit encore être verni ultérieurement,

  
 <EMI ID=2.1> 

  
 <EMI ID=3.1>  vernissage intérieur, un vernis coûteux, entièrement dépourvu de goût et capable de résister aux acides ou agents analogues. Lorsque pour le vernissage extérieur on applique le vernis à l'aide d'une brosse, l'inconvénient se présente que l'extré-

  
 <EMI ID=4.1> 

  
qui est située en amont dans le sens de l'avancement des viroles, puise en quelque sorte dans l'intérieur de la virole, durant le mouvement relatif par rapport à la brosse, le vernis adhérant à celle-ci, de sorte que la face intérieure du joint longitudinal de la virole se trouve enduite d'un vernis impropre.

  
Suivant l'invention, on obvie à cet inconvénient en guidant la brosse, opérant le vernissage extérieur, selon le profil du joint longitudinal infléchi en forme de selle, de telle manière que juste avant de rencontrer la virole la brosse s'écarte et ne vienne appuyer de l'extérieur sur le joint longitudinal que lorsque le bord circulaire de la virole est passé au-delà.

  
La Fig. 2 du dessin annexé représente un exemple d'exécution de l'invention.

  
Les viroles de tôle d qu'on veut vernir extérieurement sur le joint longitudinal a avancent sur un mandrin e dans le sens de la flèche f. En-dessous du mandrin d, un galet vernisseur h garni de soies [pound] est tourillonné sur l'extrémité d'amont d'un balancier m oscillant autour du pivot fixe k et attaqué par une bielle 2 commandée par une came n.

  "Device for varnishing the longitudinal joints of sheet metal shells on the outside, in particular for cans **.

  
When welding the superimposed edges of a tin can ferrule or the like, which. are used to form a longitudinal seal, as a result of the heat accumulation a ferrule is always obtained, the longitudi-

  
 <EMI ID = 1.1>

  
this is shown in an exaggerated manner in FIG. 1 of the accompanying drawing. The welded longitudinal joint of these ferrules, which are generally made of a strip of non-tinned sheet metal, varnished excluding the edges, must still be varnished subsequently,

  
 <EMI ID = 2.1>

  
 <EMI ID = 3.1> interior varnish, an expensive varnish, entirely tasteless and capable of withstanding acids or the like. When the varnish is applied with a brush for exterior varnishing, the drawback arises that the extreme

  
 <EMI ID = 4.1>

  
which is located upstream in the direction of advance of the ferrules, draws in a way from the interior of the ferrule, during the relative movement with respect to the brush, the varnish adhering to the latter, so that the face inside the longitudinal seal of the shell is coated with an unsuitable varnish.

  
According to the invention, this drawback is obviated by guiding the brush, carrying out the external varnishing, according to the profile of the longitudinal joint bent in the form of a saddle, so that just before meeting the ferrule the brush moves aside and does not come press from the outside on the longitudinal seal only when the circular edge of the ferrule has passed beyond it.

  
Fig. 2 of the appended drawing represents an exemplary embodiment of the invention.

  
The sheet metal ferrules d which we want to varnish externally on the longitudinal seal a advance on a mandrel e in the direction of arrow f. Below the mandrel d, a varnishing roller h lined with bristles [pound] is journaled on the upstream end of a balance m oscillating around the fixed pivot k and driven by a connecting rod 2 controlled by a cam n.

Claims (1)

<EMI ID=10.1> <EMI ID = 10.1> Le nouveau dispositif assure un vernissage satisfaisant des joints longitudinaux des viroles, sans que le vernis puisse atteindre le côté intérieur de la boite et sans que la pellicule de vernis appliquée sur le joint ait une épaisseur inégale suivant la longueur du joint. The new device ensures satisfactory varnishing of the longitudinal joints of the ferrules, without the varnish being able to reach the inside of the box and without the film of varnish applied to the joint having an unequal thickness along the length of the joint. REVENDICATIONS l.- Dispositif pour vernir extérieurement les joints longitudinaux de viroles de tôle, notamment pour boîtes à conserves, caractérisé en ce que la brosse ou son équivalent, opérant le vernissage extérieur, est guidée suivant le profil du joint longitudinal des viroles, infléchi en forme de selle, de telle manière que juste avant de rencontrer la virole la brosse s'écarte et ne vienne appuyer contre la face extérieure du joint longitudinal que lorsque le bord circulaire de la virole est passé au-delà. l.- Device for externally varnishing the longitudinal joints of sheet metal shells, in particular for cans, characterized in that the brush or its equivalent, operating the exterior varnishing, is guided along the profile of the longitudinal joint of the shells, bent in shape saddle, in such a way that just before meeting the ferrule the brush moves aside and does not press against the outer face of the longitudinal seal until the circular edge of the ferrule has passed beyond. 2.- Dispositif pour vernir extérieurement les joints longitudinaux de viroles de tôle, notamment pour boîtes à ,conserves, en substance tel que décrit ci-dessus avec référence au dessin annexé. 2.- Device for externally varnishing the longitudinal joints of sheet metal ferrules, in particular for cans, in substance as described above with reference to the attached drawing.
