Description

       

  "Brosse composa de boucles métalliques hélicoïdales" La présente invention a trait à une brosse composée de boucles métalliques formées par torsion hélicoïdale d'un ruban obtenu par laminage de fil d'acier inoxydable.

  
Les brosses métalliques de ce genre connues jusqu'à présent se composent de copeaux métalliques, tels que des copeaux d'aluminium ou d'acier inoxydable; formés au tour ou avec une autre machine-outil appropriée par un ouvrier spécialisé, et qui à leur sortie de la machine sont saisis et tordus de manière à former des boucles filiformes destinées à la confection des brosses.

  
Ce procédé connu présente toutefois l'inconvénient de modifier à fond les caractéristiques du métal, et cela à un degré tel qu'il devient fragile, perd toute résistance mécanique et devient inutilisable aux usages auxquels il est destiné normalement.

  
Or, la présente invention se propose de remédier à ces inconvénients du procédé de fabrication traditionnel des brosses composées de boucles métalliques et prévoit à cet effet la fabrication d'un ruban d'acier inoxydable par laminage d'un fil de ce métal, effectué en des conditions telles que les caractéristiques du métal ne sont pas altérées et . que le mé-

et aux influences nuisibles auxquelles il est soumis lorsde ses applications.

  
Les caractéristiques et avantages de l'invention ressortiront plus clairement de la description suivante d'un mode d'exécution préféré, donnée à titre purement indicatif sans intention restrictive aucune et illustrée par le dessin annexé, où la figure 1 représente en vue latérale un ruban métallique rectifié, mais déjà tordu par laminage;



  "Brush composed of helical metal loops" The present invention relates to a brush composed of metal loops formed by helical twisting of a ribbon obtained by rolling stainless steel wire.

  
Metal brushes of this type known hitherto consist of metal shavings, such as aluminum or stainless steel shavings; formed on a lathe or with another suitable machine tool by a specialized worker, and which when they leave the machine are grasped and twisted so as to form threadlike loops intended for making the brushes.

  
However, this known process has the drawback of completely modifying the characteristics of the metal, and this to a degree such that it becomes brittle, loses all mechanical strength and becomes unusable for the uses for which it is normally intended.

  
However, the present invention proposes to remedy these drawbacks of the traditional method of manufacturing brushes composed of metal loops and provides for this purpose the manufacture of a stainless steel strip by rolling a wire of this metal, carried out in conditions such that the characteristics of the metal are not altered and. that the m-

and the harmful influences to which it is subjected during its applications.

  
The characteristics and advantages of the invention will emerge more clearly from the following description of a preferred embodiment, given purely as an indication without any restrictive intention and illustrated by the appended drawing, where FIG. 1 represents a side view of a tape. metal rectified, but already twisted by rolling;

Claims

FIG. 2 represents a loop obtained by helical winding of the twisted ribbon according to FIG. 1; and FIG. 3 represents a toric-shaped brush composed of loops according to FIG. 2.

The metal tape 1 according to Figure 1 of the accompanying drawing is obtained by rolling a metal wire under the conditions required to give it the required properties.

ribbon come from the twisting caused by the winding in the form of a helical loop 3, intended for the manufacture of the toric-shaped brush, shown in Figure 3 and obtained by entangling such loops.

1.- Brush composed of helical metal loops, characterized in that it is composed of metal loops obtained by longitudinal twisting of a metal strip formed by rolling, the helical metal loop thus formed having a cross section whose diameter is a function of the spiral ribbon screw thread, and in that it is obtained in toroidal form by entanglement of such loops.

2.- Brush composed of helical metal loops, in substance according to the previous description and the attached drawing.
