  • form a border adjacent to the main portion along the rounded edge.

Grâce à l'invention, la fabrication de panneaux peut faire intervenir un nombre réduit d'opérations, pouvant nécessiter par exemple seulement des opérations de découpe et de pliage.Thanks to the invention, the manufacture of panels can involve a number reduced operations, which may require, for example, only cutting operations and folding.

Le procédé de fabrication selon l'invention peut notamment être dépourvu d'étape d'emboutissage de la feuille en tôle.The manufacturing method according to the invention can in particular be devoid of step of stamping the sheet metal sheet.

De plus, les formes découpées dans la feuille en tôle peuvent être relativement simples.In addition, the shapes cut from the sheet metal sheet can be relatively Simple.

Le procédé de fabrication selon l'invention peut en outre être mis en oeuvre sur une machine adaptée pour la fabrication de différents formats de panneaux et/ou avec des bords arrondis de formes et dimensions différentes. The manufacturing method according to the invention can also be implemented on a machine suitable for the manufacture of different formats of panels and / or with rounded edges of different shapes and sizes.

Avantageusement, le procédé comporte les étapes suivantes :

  • former deux parties de bordure séparées, l'une au moins étant destinée à épouser le bord arrondi de la partie principale,
  • assembler lesdites deux parties de bordure et les solidariser, notamment par soudure.
Advantageously, the method comprises the following steps:
  • forming two separate edge portions, at least one of which is intended to conform to the rounded edge of the main portion,
  • assemble said two edge portions and secure them, in particular by welding.

Dans un exemple de mise en oeuvre de l'invention, l'une des parties de bordure précitées s'étend uniquement le long d'un bord rectiligne de la partie principale.In an exemplary implementation of the invention, one of the border parts aforementioned extends only along a straight edge of the main part.

Avantageusement, une première des parties de bordure précitées comporte, à son extrémité à laquelle se raccorde une deuxième des parties de bordure, un décrochement ayant notamment une profondeur sensiblement égale à l'épaisseur de la deuxième partie de bordure.Advantageously, a first of the aforementioned border portions comprises, at its end to which is connected a second edge portions, a recess having in particular a depth substantially equal to the thickness of the second part of border.

Dans un exemple de mise en oeuvre de l'invention, le bord arrondi de la surface d'affichage présente une forme en arc de cercle, et peut être réalisé par découpe de la feuille en tôle.In an exemplary implementation of the invention, the rounded edge of the surface display is in a circular arc shape, and can be made by cutting the sheet metal sheet.

On va décrire ci-après un procédé de fabrication d'un panneau de signalisation conforme à l'invention.A method of manufacturing a traffic sign will be described below. according to the invention.

On part d'une feuille en tôle 1 ayant des propriétés mécaniques permettant le pliage, étant réalisée par exemple en acier ou en alliage d'aluminium.Starting from a sheet metal sheet 1 having mechanical properties allowing the folding, being made for example of steel or aluminum alloy.

La feuille 1 subit préalablement des opérations de découpe de manière à former une partie principale destinée à défmir une surface d'affichage 2.The sheet 1 is previously subjected to cutting operations so as to form a main part for defining a display surface 2.

Cette surface d'affichage 2 présente, dans l'exemple considéré, une forme sensiblement rectangulaire avec quatre coins constitués chacun par un bord arrondi 3, en arc de cercle.This display surface 2 has, in the example under consideration, a shape substantially rectangular with four corners each consisting of a rounded edge 3, in arc.

Chaque arc de cercle est défini par un secteur angulaire A de 90°, comme on peut le voir sur la figure 2. Each arc of circle is defined by an angular sector A of 90 °, as one can see it in Figure 2.

En variante, la surface d'affichage 2 peut présenter une forme en flèche et comporter cinq bords arrondis, à savoir deux bords arrondis à 90°, deux bords arrondis à 142,5° et un bord arrondi à 75° par exemple.As a variant, the display surface 2 may have an arrow shape and have five rounded edges, ie two rounded edges at 90 °, two rounded edges to 142.5 ° and a rounded edge at 75 ° for example.

En variante encore, la surface d'affichage 2 peut présenter une forme triangulaire, avec trois bords arrondis à 60°.In another variant, the display surface 2 may have a shape triangular, with three rounded edges at 60 °.

Le panneau peut encore présenter une surface d'affichage 2 ayant une forme octogonale avec huit bords arrondis à 135°.The panel may still have a display surface 2 having a shape octagonal with eight rounded edges at 135 °.

Bien entendu, la surface d'affichage 2 peut présenter toute autre forme.Of course, the display surface 2 may have any other shape.

La feuille 2, après découpe, comporte en outre sur deux côtés opposés du rectangle, des premières parties de bordure 5 s'étendant parallèlement à un axe X.The sheet 2, after cutting, further comprises on two opposite sides of the rectangle, first border portions 5 extending parallel to an axis X.

Chaque partie 5 comporte une première région rectangulaire 5a adjacente à la surface d'affichage 2, et une deuxième région rectangulaire 5b se raccordant à la première région 5a et s'étendant parallèlement à cette première région 5a.Each portion 5 has a first rectangular region 5a adjacent to the display surface 2, and a second rectangular region 5b connecting to the first region 5a and extending parallel to this first region 5a.

La deuxième région 5b présente une longueur, mesurée parallèlement à l'axe X, supérieure à celle de la région 5a de manière à définir deux extrémités 6 qui font saillie de part et d'autre de la région 5a lorsque la région 5b est pliée sous celle 5a.The second region 5b has a length, measured parallel to the axis X, greater than that of the region 5a so as to define two ends 6 which protrude on both sides of the region 5a when the region 5b is folded under that 5a.

Les régions 5a et 5b ont une même largeur mesurée dans une direction perpendiculaire à l'axe X.Regions 5a and 5b have the same width measured in one direction perpendicular to the X axis.

La feuille 1 comporte en outre, adjacentes à deux autres côtés opposés de la surface d'affichage, des deuxièmes parties de bordure 8 s'étendant perpendiculairement à l'axe X.The sheet 1 further comprises adjacent two other opposite sides of the display surface, second border portions 8 extending perpendicular to the X axis.

Chaque partie de bordure 8 comporte, de part et d'autre d'une région centrale rectangulaire 9, deux portions d'extrémité ou languettes 10.Each edge portion 8 comprises, on either side of a central region rectangular 9, two end portions or tongues 10.

Chaque languette 10 présente une forme rectangulaire avec un bord 11 ayant une longueur sensiblement égale à la longueur de l'arc de cercle du bord arrondi 3.Each tongue 10 has a rectangular shape with an edge 11 having a length substantially equal to the length of the arc of the rounded edge 3.

La feuille 1 subit, après découpe, des opérations de pliage permettant de plier les parties de bordure 8 de manière à ce que celles-ci s'étendent sensiblement perpendiculairement à la partie principale, comme illustré sur la figure 2.The sheet 1 undergoes, after cutting, folding operations to fold the edge portions 8 so that these extend substantially perpendicular to the main part, as shown in Figure 2.

Chaque région 5b est rabattue sous celle 5a et la portion 5 est pliée de manière à former une portion de bordure.Each region 5b is folded under that 5a and the portion 5 is folded so that to form a border portion.

Une fois les parties de bordure 5 et 8 pliées, les languettes 10 sont rabattues par pliage sur les extrémités 6 des parties de bordure 5, comme on peut le voir sur la figure 3. Once the edge portions 5 and 8 folded, the tabs 10 are folded by folding on the ends 6 of the edge portions 5, as can be seen in Figure 3.

La languette 10 peut être soudée sur l'extrémité 6 correspondante, par exemple.The tongue 10 may be welded to the corresponding end 6, for example.

On obtient un panneau de signalisation 15 avec quatre coins arrondis formés par les languettes 10, la bordure s'étendant sur toute la périphérie de la surface d'affichage 2 et étant sensiblement dépourvue de relief en saillie vers l'extérieur.A traffic sign 15 is obtained with four rounded corners formed by the tabs 10, the border extending over the entire periphery of the display surface 2 and being substantially devoid of outwardly projecting relief.

Toutes les opérations de découpe et de pliage peuvent être effectuées sur une seule machine adaptée.All cutting and folding operations can be performed on a only adapted machine.

Bien entendu, les parties de bordure 5 peuvent être réalisées sur les petits côtés du rectangle et non sur les grands côtés.Of course, the border portions 5 can be made on the short sides of the rectangle and not on the long sides.

On a représenté en référence aux figures 4 à 6 un autre exemple de mise en oeuvre de l'invention.FIGS. 4 to 6 show another example of implementation. of the invention.

Le procédé, dans l'exemple considéré, se différencie du procédé précédemment décrit par le fait que la partie de bordure 5' comporte une seule région au lieu de deux 5a et 5b décrites dans l'exemple précédent.The process, in the example under consideration, differs from the process previously characterized in that the border portion 5 'has a single region instead of two 5a and 5b described in the previous example.

La languette 10' se distingue de la languette 10 précédemment décrite par le fait qu'un décrochement 16 est réalisé à son extrémité, ce décrochement ayant une profondeur sensiblement égale à l'épaisseur de la feuille en tôle.The tongue 10 'is distinguished from the tongue 10 previously described by the fact that a recess 16 is formed at its end, this recess having a depth substantially equal to the thickness of the sheet metal sheet.

Comme on peut le voir sur la figure 5, pour réaliser un coin arrondi du panneau, on plie la partie de bordure 8 avec la languette 10', puis on rabat cette languette 10' de manière à ce qu'elle épouse le bord arrondi 3 de la surface d'affichage 2.As can be seen in FIG. 5, to make a rounded corner of the panel, we bend the edge portion 8 with the tongue 10 ', then we fold this tab 10 'so that it matches the rounded edge 3 of the display surface 2.

La partie de bordure 5' est rabattue par pliage de manière à venir s'appliquer sur le décrochement 16 de la languette 10', comme illustré sur la figure 6.The edge part 5 'is folded down so as to come to apply on the recess 16 of the tongue 10 ', as shown in Figure 6.

L'une des parties de bordure peut comporter un pli écrasé 17, comme illustré sur la figure 7.One of the edge portions may include a crushed fold 17, as illustrated in Figure 7.

Dans les exemples qui viennent d'être décrits, le panneau de signalisation est réalisé d'un seul tenant à partir d'une feuille unique en tôle.In the examples just described, the road sign is made in one piece from a single sheet of sheet metal.

On ne sort pas du cadre de la présente invention lorsque le panneau de signalisation comporte un assemblage de pièces indépendantes.It is not beyond the scope of the present invention when the signaling comprises an assembly of independent parts.

On a représenté, en référence aux figures 8 à 11, un exemple de mise en oeuvre de l'invention dans lequel la feuille en tôle 19 comporte quatre parties de bordure 21 de forme rectangulaire et se raccordant chacune à un côté du rectangle de la surface d'affichage 20. FIGS. 8 to 11 show an example of implementation. of the invention wherein the sheet metal sheet 19 has four edge portions 21 of rectangular shape and each connected to one side of the rectangle of the surface Display 20.

Les parties de bordure 21 sont pliées perpendiculairement à la surface d'affichage 20, comme illustré sur la figure 9.The edge portions 21 are folded perpendicular to the surface 20, as shown in FIG. 9.

Les parties 21 ménagent dans les coins du panneau des espaces 22.The parts 21 form spaces in the corners of the panel 22.

Des inserts 23 sont fixés chacun sur deux parties 21 voisines, dans un espace 22, comme illustré sur la figure 10.Inserts 23 are each attached to two adjacent parts 21, in a space 22, as illustrated in Figure 10.

Chaque insert 23 peut être obtenu par formage d'une tôle ou par moulage d'un matériau métallique ou plastique, et comporte à chaque extrémité un décrochement 24, réalisé notamment par formage, comme illustré sur la figure 11.Each insert 23 can be obtained by forming a sheet or by molding a metal or plastic material, and comprises at each end a recess 24, produced in particular by forming, as illustrated in FIG. 11.

Chaque insert 23 présente une forme sensiblement de bande arrondie, agencée pour épouser un bord arrondi de la surface d'affichage 20.Each insert 23 has a substantially rounded band shape, arranged to fit a rounded edge of the display surface 20.

Chaque insert 23 est solidarisé aux parties 21 par soudure, collage, clinchage ou tout autre procédé d'assemblage.Each insert 23 is secured to the parts 21 by welding, gluing, clinching or any other method of assembly.
