Description
La présente invention concerne un procédé de fabrication d'un profilé formant pince, à section en U, comprenant une armature métallique gainée d'une matière plastique, notamment pour joints d'étanchéité pour organes d'automobiles. L'invention a également pour objet les profilés réalisés par un tel procédé. The present invention relates to a method for manufacturing a profile forming a clamp, with a U-shaped section, comprising a metal frame sheathed with a plastic material, in particular for seals for automobile components. The invention also relates to the profiles produced by such a method.
On sait que les joints d'étanchéité pour organes d'automobiles comprennent usuellement, d'une part, un profilé formant pince, apte à coiffer une partie en saillie ou une feuillure de la carrosserie et, d'autre part, un élément d'étanchéité proprement dit, comprenant, par exemple, une levre d'étanchéité et/ou une partie tubulaire destinée à être pincée entre un encadrement de porte et la porte associée. It is known that the seals for automobile components usually comprise, on the one hand, a profile forming a clamp, capable of covering a projecting part or a rebate of the bodywork and, on the other hand, an element of sealing proper, comprising, for example, a sealing lip and / or a tubular part intended to be pinched between a door frame and the associated door.
Le profilé formant pince comprend habituellement une âme métallique longitudinale à section en U, gainée d'une matière plastique telle que le polychlorure de vinyle plastifié, qui a été extrudée sur l'âme métallique. Sur les faces des branches en U disposées en vis-à-vis, la matière plastique comporte des parties en saillie telles que des lèves inclinées vers la base du U, qui s'escamotent lors de la mise en place de la partie formant pince sur le bord saillant de la feuillure associée de la carrosserie et qui s'opposent à une désolidarisation accidentelle de cette partie formant pince. The clamp profile usually comprises a longitudinal metal core with a U-section, sheathed in a plastic material such as plasticized polyvinyl chloride, which has been extruded on the metal core. On the faces of the U-shaped arms arranged facing each other, the plastic material has protruding parts such as lifts inclined towards the base of the U, which retract during the positioning of the clamp part on the projecting edge of the associated rebate of the bodywork and which oppose accidental detachment of this part forming a clamp.
Les armatures des pinces sont généralement ajourées et elles sont, par exemple, découpées suivant les branches du U en lamelles parallèles, réunies à intervalles réguliers par des entretoises perpendiculaires, disposées suivant les branches du U et/ou suivant l'axe de la base de ce U. Les ajours de l'armature ou les intervalles entre lamelles sont cependant souvent visibles de ltextérieur, où une succession de rides parallèles apparat à la surface externe des bandes du U en y formant des côtes séparées par des parties en creux. The armatures of the clamps are generally perforated and they are, for example, cut along the branches of the U into parallel strips, joined at regular intervals by perpendicular spacers, arranged along the branches of the U and / or along the axis of the base of this U. The openings of the reinforcement or the intervals between lamellae are however often visible from the inside, where a succession of parallel wrinkles appears on the external surface of the bands of the U, forming there ribs separated by hollow parts.
Ces défauts de la surface extérieure de la pince sont d'autant plus inesthétiques que la pince elle-même participe habituellement à l'enjolivement de la carrosserie sur laquelle elle est fixée. Aussi a-t-on proposé, pour atténuer cet inconvénient, par exemple dans
FR-A-2 591 971, d'interposer entre l'armature métallique du profilé et la face externe de la bande du U visible de une unepièce continue, faite par exemple de métal, qui est noyée dans la matière plastique gainant l'armature métallique et qui dissimule ainsi de l'extérieur les découpes de l'armature.These defects of the external surface of the clamp are all the more unsightly as the clamp itself usually participates in the embellishment of the bodywork on which it is fixed. It has therefore been proposed, to mitigate this drawback, for example in
FR-A-2 591 971, to interpose between the metal reinforcement of the profile and the external face of the visible U-band of a continuous piece, made for example of metal, which is embedded in the plastic material sheathing the reinforcement metallic and thus conceals from the outside the cutouts of the frame.
Ce processus est cependant long et coûteux, du fait de l'utilisation d'un élément additionnel à incorporer dans le profilé. This process is however long and costly, due to the use of an additional element to be incorporated into the profile.
La présente invention vise à remédier à cet inconvénient en proposant un procédé facile à mettre en oeuvre et d'un coût réduit, pour dissimuler efficacement de ltextérieur les découpes pratiquées dans les armatures des profilés formant pince du type défini ci-dessus. The present invention seeks to remedy this drawback by proposing a method which is easy to implement and of reduced cost, for effectively concealing from the inside the cutouts made in the frames of the profiles forming a clamp of the type defined above.
A cet effet, l'invention a pour objet un procédé de fabrication d'un profilé formant pince à section en U, à armature métallique ajourée noyée dans un corps en matière plastique, du type dans lequel on extrude en continu à l'état de fusion pâteuse la matière plastique sur l'armature, on laisse durcir la matière plastique constituant le corps du profilé par refroidissement et l'on forme en U le composite ainsi réalisé, ce procédé étant caractérisé en ce que, dans une phase préliminaire, on gaine au moins une partie de l'armature métallique d'une mince couche d'une matière plastique auxiliaire, de manière à obturer les ajours, découpes ou intervalles ménagés dans cette armature métallique et en ce qu'on laisse se solidifier cette matière plastique auxiliaire avant de procéder à l'extrusion de la matière plastique constituant le corps du profilé. To this end, the subject of the invention is a method of manufacturing a profile forming a U-section clamp, with an openwork metal frame embedded in a plastic body, of the type in which one continuously extrudes in the state of pasty melting the plastic on the frame, the plastic constituting the body of the profile is allowed to harden by cooling and the composite thus produced is U-shaped, this process being characterized in that, in a preliminary phase, the sheath is sheathed at least part of the metal frame with a thin layer of an auxiliary plastic material, so as to seal the openings, cutouts or intervals formed in this metal frame and in that this auxiliary plastic material is allowed to solidify before to carry out the extrusion of the plastic material constituting the body of the profile.
La Demanderesse a établi que, par ce procédé, du fait que les ajours, découpes ou intervalles ménagés dans l'armature métallique ont été préalablement obturés par la matière plastique auxiliaire, ils n'exercent plus d'effet d'aspiration saccadée sur la matière plastique constituant le corps du profilé, à la sortie de la filière d'extrusion de cette matière plastique, comme c'était le cas par le passé, ce qui se traduisait par l'apparition en surface de dépressions et de côtes reproduisant la surface de l'armature métallique. The Applicant has established that, by this process, owing to the fact that the openings, cutouts or intervals formed in the metal frame have been previously closed by the auxiliary plastic material, they no longer exert a jerky suction effect on the material plastic constituting the body of the profile, at the outlet of the extrusion die of this plastic material, as was the case in the past, which resulted in the appearance on the surface of depressions and ribs reproducing the surface of the metal frame.
Par le procédé conforme à l'invention, au contraire, l'armature métallique ayant été préalablement traitée de manière à se présenter sous la forme d'un corps sensiblement continu, sans découpes, ajours ou intervalles, l'extrusion de la matière constituant le corps du profilé s'effectue de façon parfaitement régulière, sans pulsations, et conduit à une surface unie, sans la moindre discontinuité. By the process according to the invention, on the contrary, the metal reinforcement having been previously treated so as to be in the form of a substantially continuous body, without cuts, openings or intervals, the extrusion of the material constituting the profile body is carried out in a perfectly regular manner, without pulsations, and leads to a smooth surface, without the slightest discontinuity.
La matière plastique auxiliaire pourra être identique ou non à celle constituant le corps du profilé. The auxiliary plastic material may or may not be identical to that constituting the body of the profile.
La matière plastique auxiliaire pourra, elle aussi, être déposée sur l'armature par extrusion. The auxiliary plastic material may also be deposited on the frame by extrusion.
L'épaisseur de la pellicule de cette matière plastique recouvrant les parties pleines de l'armature métallique sera de de 1 l'ordre de quelques centièmes de millimètre, par exemple entre 30 et 40 centièmes de millimètre. Dans les découpes de l'armature, l'épaisseur de la couche de matière plastique auxiliaire sera égale à celle de l'armature, augmentée de l'épaisseur se trouvant de part et d'autre sur les parties pleines. The thickness of the film of this plastic material covering the solid parts of the metal frame will be of the order of a few hundredths of a millimeter, for example between 30 and 40 hundredths of a millimeter. In the cutouts of the frame, the thickness of the layer of auxiliary plastic material will be equal to that of the frame, increased by the thickness on either side on the solid parts.

Figure 6 is a perspective view of such a profile integrated in a sealing system.
Le profilé d'un type connu représenté sur la figure 1 comprend une armature métallique 1, en acier laminé ou en aluminium, par exemple, qui est gainée d'une matière plastique 2 telle que du polychlorure de vinyle, constituant le corps du profilé. De façon connue en soi, le profilé est replié en forme d'auge à section en U, de manière à pouvoir venir pincer une feuillure ou un autre élément de carrosserie et il présente, sur les faces internes des bandes du U, des lèvres 6 inclinées en direction de la base du U, de manière à bloquer le profilé sur l'élément de carrosserie qui lui sert de support. The profile of a known type shown in Figure 1 comprises a metal frame 1, rolled steel or aluminum, for example, which is sheathed with a plastic 2 such as polyvinyl chloride, constituting the body of the profile. In a manner known per se, the profile is folded in the shape of a trough with a U-shaped section, so as to be able to pinch a rebate or another bodywork element and it has lips 6 on the internal faces of the bands of the U inclined towards the base of the U, so as to block the profile on the bodywork element which serves as its support.
L'armature 1 peut être de tout type connu et elle est généralement ajourée. Dans le cas présent, elle comporte, avant pliage en U, des lamelles parallèles 3, reliées deux à deux, alternativement, par des entretoises latérales 4, disposées symétriquement par rapport au plan de symétrie du profilé, et par une entretoise médiane 5, disposée suivant ce plan de symétrie. Comme on le voit sur la figure 1, les espaces entre lamelles 3 se traduisent à la surface du profilé par des dépressions 7, dont l'ampleur a été fortement exagérée sur la figure 1, mais qui n'en sont pas moins inesthétiques et nuisent à l'aspect d'ensemble du profilé. The frame 1 can be of any known type and is generally perforated. In this case, it comprises, before folding into a U, parallel strips 3, connected in pairs, alternately, by lateral spacers 4, arranged symmetrically with respect to the plane of symmetry of the profile, and by a central spacer 5, arranged following this plane of symmetry. As can be seen in FIG. 1, the spaces between the lamellae 3 are reflected on the surface of the profile by depressions 7, the magnitude of which has been greatly exaggerated in FIG. 1, but which are nonetheless unsightly and harm the overall appearance of the profile.
Pour remédier à cet inconvénient, l'invention propose de faire précéder l'opération d'extrusion sur l'armature 1 de la matière plastique 2 constituant le corps du profilé d'un pré-enrobage de cette armature à l'aide d'une matière plastique auxiliaire 8, qui peut être identique ou non à la matière 2. To remedy this drawback, the invention proposes to precede the extrusion operation on the frame 1 of the plastic 2 constituting the body of the profile with a pre-coating of this frame using a auxiliary plastic material 8, which may or may not be identical to material 2.
Conformément à 1 invention, on commence donc par noyer l'armature 1 dans une très mince couche d'une matière plastique 8, de manière à obturer tous les intervalles entre lamelles 3 et à ne recouvrir ces lamelles et les entretoises 4 et 5 que d'une mince pellicule de quelques centièmes de millimètre d'épaisseur. In accordance with the invention, one therefore begins by drowning the reinforcement 1 in a very thin layer of plastic material 8, so as to close all the intervals between the lamellae 3 and to cover these lamellae and the spacers 4 and 5 only d 'a thin film a few hundredths of a millimeter thick.
Le dépôt de la matière 8 sur l'armature peut s'effectuer par extrusion. Ce pré-enrobage peut s'appliquer à la totalité ou à une partie seulement de l'armature 1. Dans le cas de la figure 3, la totalité de l'armature 1 est noyée dans la matière plastique 8 de pré-enrobage, et celle-ci enrobe également des fils 9 en une matière inextensible disposés de préférence suivant la fibre neutre 1 moyenne du profilé et destinés à assurer une courbure correcte du profilé, lorsque ceci est nécessaire, comme décrit dans le brevet français n0 2 452 643.The deposition of the material 8 on the frame can be carried out by extrusion. This pre-coating can be applied to all or only part of the frame 1. In the case of FIG. 3, the whole of the frame 1 is embedded in the plastic material 8 for pre-coating, and the latter also coats the wires 9 in an inextensible material preferably arranged along the neutral neutral fiber 1 of the profile and intended to ensure correct curvature of the profile, when this is necessary, as described in French Patent No. 2,452,643.
Après solidification de la matière 8, la matière plastique 2 constitutive du corps du profilé est extrudée, de façon connue en soi, sur le pré-ensembles de la figure 3, pour conduire au système multi-couche de la figure 4, qu'il suffit ensuite de former en U pour obtenir le profilé de la figure 5. Du fait de l'obturation préalable des découpes de l'armature 1 avec la matière plastique auxiliaire 8, aucune déformation n'apparat plus à la surface externe du profilé, qui est parfaitement lisse et ne nuit donc pas à l'aspect ornemental du véhicule qu'il équipe. After solidification of the material 8, the plastic 2 constituting the body of the profile is extruded, in a manner known per se, onto the pre-assemblies of FIG. 3, to lead to the multilayer system of FIG. 4, which it It then suffices to form a U to obtain the profile of FIG. 5. Due to the prior sealing of the cutouts of the frame 1 with the auxiliary plastic material 8, no deformation appears any longer on the external surface of the profile, which is perfectly smooth and therefore does not harm the ornamental aspect of the vehicle it equips.
Bien entendu, l'invention ne s'applique pas seulement à la réalisation d'un profilé à section en mais à la réalisation de tous les éléments, notamment d'étanchéité ou d'enjolivement, faisant corps avec un tel profilé. A titre d'exemple, un tel ensemble, représenté sur la figure 6, comprend un profilé 10 à section en U conforme à l'invention, auquel est attenante, d'une part, une lèvre 11 d'enjolivement en la même matière et coextrudée avec le profilé et, d'autre part, un bourrelet tubulaire d'étanchéité 12 en caoutchouc cellulaire, également coextrudé, destiné à être pincé entre un battant et un dormant. Of course, the invention does not only apply to the production of a sectional section, but to the production of all the elements, in particular sealing or embellishment, being integral with such a profile. By way of example, such an assembly, shown in FIG. 6, comprises a profile 10 with a U-section in accordance with the invention, to which is attached, on the one hand, a lip 11 embellished in the same material and coextruded with the profile and, on the other hand, a tubular sealing bead 12 of cellular rubber, also coextruded, intended to be pinched between a leaf and a frame.
Bien entendu, bien d'autres ensembles incorporant le profilé conforme à l'invention pourraient être conçus sans sortir du cadre de celle-ci. Of course, many other assemblies incorporating the profile according to the invention could be designed without departing from the scope thereof.
