Abstract

The process makes it possible to bond a glass or metal panel 1 onto a frame 2. First of all a profile 4 made of deformable plastic, in which an electrically resistant element 5 is embedded, projecting on one 6 of the side faces of this profile, is bonded to the panel 1. A bead 7 of hot-melt substance is then applied against the surface of the panel between the outer edge 3 of this panel and the side face 6 of the profile 4 so that the bead 7 is in contact with the part 5a of the electrically resistant element 5, after which the panel 1 fitted with its bead 7 is pressed in a known manner against the frame 2 and an electrical voltage is applied to the terminals of the electrically resistant element 5 to heat the bead. Use especially for bonding the windscreens and rear windows of motor vehicles onto the corresponding bays.

Description

La présente invention concerne un procédé pour coller un panneau en verre ou en métal et en particulier un pare-brise ou une lunette arrière d'automobile sur un cadre tel que la baie d'une automobile. The present invention relates to a method for bonding a glass or metal panel and in particular a windshield or a rear window of an automobile on a frame such as the bay of an automobile.

L'invention vise également un profilé en matière plastique déformable utilisé dans le procédé conforme à l'invention ainsi qu'un panneau en verre ou métal, en particulier un pare-brise ou une lunette arrière d'automobile prêt à être fixé par collage sur un cadre tel que la baie d'une automobile. The invention also relates to a deformable plastic profile used in the process according to the invention as well as a glass or metal panel, in particular a windshield or a rear window of an automobile ready to be fixed by gluing to a frame like the bay of an automobile.

On connais déjà un procédé dans lequel on fixe autour du panneau à coller sur un cadre, un cordon en matière adhésive thermofusible, on presse le panneau muni de son cordon contre le cadre et on chauffe ce cordon par effet Joule. A process is already known in which a cord made of hot-melt adhesive material is fixed around the panel to be glued to a frame, the panel provided with its cord is pressed against the frame and the cord is heated by the Joule effect.

Pour réaliser le chauffage par effet Joule, on incorpore dans le cordon en matière adhésive thermofusible, un élément électriquement résistant dont les bornes sont raccordées à une source de courant électrique. To make the heating by Joule effect, an electrically resistant element is incorporated in the cord made of hot-melt adhesive material, the terminals of which are connected to a source of electric current.

L'inconvénient majeur de ce procédé res;#e dans le fait que lors de l'application de la et du chauffage, le cordon en matière thermofus.  The major drawback of this process res; #e in the fact that during the application of the and heating, the bead of thermofus material.

s'écrase d'une manière irrégulière contre le cadre, de sorte que le bord de ce cordon tourné vers l'intérieur du panneau s'étend suivant une ligne plus ou moins sinueuse non parallèle au bord extérieur du panneau.crashes irregularly against the frame, so that the edge of this cord facing the inside of the panel extends along a more or less sinuous line not parallel to the outer edge of the panel.

Lorsque le panneau est en verre, le cordon est visible de l'extérieur et l'irrégularité de son bord intérieur est particulièrement inesthétique. When the panel is made of glass, the cord is visible from the outside and the irregularity of its inner edge is particularly unattractive.

Le but de la présente invention est de remédier à cet inconvénient. The object of the present invention is to remedy this drawback.

Suivant l'invention, le procédé pour coller un panneau en verre ou en métal sur un cadre dans lequel on fixe autour du panneau un cordon en matière adhésive thermofusible, est caractérisé en ce qu'on colle tout d'abord sur le panneau à une certaine distance de son bord extérieur, un profilé en matière plastique déformable dans laquelle est noyé un élément électriquement résistant faisant saillie sur l'une des faces latérales dudit profilé, on applique le cordon en matière thermofusible contre la surface du panneau dans la zone comprise entre le bord extérieur du panneau et ladite face latérale du profilé en matière plastique déformable de façon que le cordon soit en contact avec la partie de l'élément électriquement résistant qui fait saillie sur cette face latérale du profilé, après quoi de façon connue, on presse le panneau muni de son cordon contre le cadre et on applique une tension électrique aux bornes de l'élément électriquement résistant pour chauffer le cordon. According to the invention, the method for bonding a glass or metal panel to a frame in which a cord of hot-melt adhesive material is fixed around the panel, is characterized in that first of all, the adhesive is bonded to the panel. certain distance from its outer edge, a deformable plastic profile in which is embedded an electrically resistant element projecting from one of the side faces of said profile, the bead of hot-melt material is applied against the surface of the panel in the area between the outer edge of the panel and said lateral face of the profile made of deformable plastic material so that the cord is in contact with the part of the electrically resistant element which projects on this lateral face of the profile, after which in a known manner, is pressed the panel with its cord against the frame and an electrical voltage is applied across the electrically resistant element to heat the cord.

Le profilé en matière plastique déformable servant de support à l'élément électriquement résistant peut être collé avec une grande précision parallèlement au bord extérieur du panneau. En particulier, étant donné que ce profilé est déformable, ce profilé peut être plié pratiquement à angle droit pour suivre les coins à angle droit du panneau. The deformable plastic profile serving as a support for the electrically resistant element can be glued with great precision parallel to the outer edge of the panel. In particular, since this profile is deformable, this profile can be folded practically at a right angle to follow the right angle corners of the panel.

Lors de la pose du panneau contre le cadre, le cordon en matière thermofusible flue vers la face latérale du profilé sur laquelle fait saillie l'élément électriquement résistant, mais sans aller au-delà de ce profilé qui constitue ainsi une barrière qui limite l'écrasement et le fluage du cordon thermofusible. When the panel is placed against the frame, the bead of hot-melt material flows towards the lateral face of the profile on which the electrically resistant element projects, but without going beyond this profile which thus constitutes a barrier which limits the crushing and creep of the hot melt cord.

Dans le cas d'un panneau en verre tel qu'un pare-brise, le profilé est visible de l'extérieur et définit avec précision le bord intérieur du cordon en matière thermofusible en conférant à celui-ci un aspect particulièrement esthétique. In the case of a glass panel such as a windshield, the profile is visible from the outside and precisely defines the inner edge of the bead of hot-melt material, giving it a particularly aesthetic appearance.

Par ailleurs, lors de l'application du cordon en matière thermofusible contre le panneau, les parties en saillie de l'élément électriquement résistant porté par le profilé, réalisent un accrochage efficace de ce cordon au panneau et on obtient en même temps une surface de contact entre ce cordon et cet élément électriquement résistant uniforme sur toute la longueur du cordon. Ainsi lors de l'application du courant électrique aux bornes de l'élément électriquement résistant, le chauffage par effet Joule est réalisé d'une manière uniforme sur la périphérie du panneau, ce qui permet d'obtenir un collage efficace et régulier. Furthermore, during the application of the bead of hot-melt material against the panel, the protruding parts of the electrically resistant element carried by the profile, achieve effective attachment of this bead to the panel and at the same time a surface of contact between this cord and this uniform electrically resistant element over the entire length of the cord. Thus when the electric current is applied to the terminals of the electrically resistant element, the heating by Joule effect is carried out in a uniform manner on the periphery of the panel, which makes it possible to obtain an effective and regular bonding.

Selon une version avantageuse de l'invention, l'élément électriquement résistant noyé dans la matière plastique du profilé est une lamelle métallique présentant sur l'un de ses bords longitudinaux des dents régulièrement espacées les unes des autres, lesdites dents faisant saillie sur l'une des faces latérales du profilé. According to an advantageous version of the invention, the electrically resistant element embedded in the plastic of the profile is a metal strip having on one of its longitudinal edges teeth regularly spaced from one another, said teeth projecting from the one of the side faces of the profile.

Lorsqu'on plie à angle droit le profilé pour suivre un coin du panneau, les dents de l'élément électriquement résistant s'écartent les unes des autres dans la zone du pliage, de sorte qu'elles ne risquent pas d'entrer en contact les unes avec les autres en provoquant un court-circuit. When the profile is bent at a right angle to follow a corner of the panel, the teeth of the electrically resistant element move away from each other in the bending area, so that they do not risk coming into contact with each other causing a short circuit.

L'invention vise également un panneau en verre ou métal, en particulier un pare-brise ou une lunette arrière d'automobile prêt à être fixé par collage sur un cadre, tel que la baie d'une automobile. The invention also relates to a glass or metal panel, in particular a windshield or a rear window of an automobile ready to be fixed by gluing to a frame, such as the bay of an automobile.

Suivant l'invention, ce panneau comprend un profilé en matière plastique déformable collé à une certaine distance du bord extérieur du panneau, un élément électriquement résistant étant noyé dans ce profilé et faisant saillie sur l'une des faces latérales dudit profilé et un cordon en matière adhésive thermofusible est appliqué contre la surface du panneau dans la zone comprise entre le bord extérieur du panneau et ladite face latérale du profilé en matière plastique déformable de façon que le cordon soit en contact avec la partie de élément électriquement résistant qui fait saillie sur cette face latérale du profilé. According to the invention, this panel comprises a deformable plastic profile glued at a certain distance from the outer edge of the panel, an electrically resistant element being embedded in this profile and protruding on one of the lateral faces of said profile and a bead in hot-melt adhesive material is applied against the surface of the panel in the area between the outer edge of the panel and said side face of the profile made of deformable plastic material so that the bead is in contact with the part of electrically resistant element which projects therefrom. lateral face of the profile.

Pour coller un panneau 1 par exemple un parebrise ou une lunette arrière d'automobile sur un cadre 2 tel que la baie d'une automobile, on colle tout d'abord (voir figures 2 et 3) sur le panneau 1 à une certaine distance de son bord extérieur 3, un profilé 4 en matière plastique déformable dans laquelle est noyé un élément électriquement résistant 5 faisant saillie sur l'une 6 des faces latérales dudit profilé (voir également la figure 1). To glue a panel 1 for example a windshield or a rear window of an automobile on a frame 2 such as the bay of an automobile, we first glue (see Figures 2 and 3) on the panel 1 at a certain distance from its outer edge 3, a profile 4 of deformable plastic material in which is embedded an electrically resistant element 5 projecting from one 6 of the side faces of said profile (see also Figure 1).

On applique ensuite (voir figure 4) un cordon 7 en matière thermofusible contre la surface du panneau 1 dans la zone 8 comprise entre le bord extérieur 3 du panneau 1 et la face latérale 6 du profilé 4 en matière plastique déformable de façon que le cordon 7 soit en contact avec la partie Sa de l'élément électriquement résistant 5 qui fait saillie sur cette face latérale 6 du profilé 4. A bead 7 of hot-melt material is then applied (see FIG. 4) against the surface of the panel 1 in the zone 8 between the outer edge 3 of the panel 1 and the side face 6 of the profile 4 of deformable plastic material so that the bead 7 is in contact with the part Sa of the electrically resistant element 5 which projects on this lateral face 6 of the profile 4.

Dans une -dernière étape, de façon connue, on presse le panneau 1 muni de son cordon 7 et de son profilé 4 contre le cadre 2 et on applique une tension électrique aux bornes de l'élément électriquement résistant 5 pour chauffer le cordon 7. In a last step, in a known manner, the panel 1 fitted with its cord 7 and its profile 4 is pressed against the frame 2 and an electrical voltage is applied across the terminals of the electrically resistant element 5 to heat the cord 7.

Le chauffage du cordon 7 provoque le ramollissement de celui-ci. Ainsi, sous l'effet de la pression exercée sur le vitrage 1, le cordon 7 flue vers le bord extérieur 3 du vitrage et vers le profilé 4. Toutefois celui-ci constitue une barrière qui limite le fluage latéral du cordon 7, de sorte que le profilé 4 définit pour le cordon 7 un bord intérieur parfaitement net et d'aspect très esthétique. Heating the cord 7 causes it to soften. Thus, under the effect of the pressure exerted on the glazing 1, the bead 7 flows towards the outer edge 3 of the glazing and towards the profile 4. However, this constitutes a barrier which limits the lateral creep of the bead 7, so that the profile 4 defines for the bead 7 a perfectly clean inner edge and very aesthetic appearance.

Comme on le voit sur les figures 1 et 3, le profilé 4 en matière plastique déformable utilisé dans le procédé conforme à l'invention, comprend un élénient électriquement résistant 5 noyé dans la matière plastique du profilé 4 sous la forme d'une lamelle métallique présentant sur l'un de ses bords longitudinaux des dents Sa régulièrement espacées les unes des autres, ces dents Sa faisant saillie sur la face latérale 6 du profilé. As can be seen in FIGS. 1 and 3, the profile 4 made of deformable plastic material used in the process according to the invention, comprises an electrically resistant element 5 embedded in the plastic material of the profile 4 in the form of a metal strip having on one of its longitudinal edges teeth Sa regularly spaced from one another, these teeth Sa projecting from the lateral face 6 of the profile.

Les dents Sa de l'élément 5 présentent des ouvertures 5b qui permettent d'augmenter l'ancrage de ces dents Sa à la matière thermofusible du cordon 7 et en même temps elles augmentent la valeur ohmique de l'élément résistant 5. The teeth Sa of the element 5 have openings 5b which make it possible to increase the anchoring of these teeth Sa to the hot-melt material of the cord 7 and at the same time they increase the ohmic value of the resistant element 5.

Les dents Sa de l'élément électriquement résistant 5 sont reliées les unes aux autres par une bande métallique 5c suffisamment mince pour être pliable. The teeth Sa of the electrically resistant element 5 are connected to each other by a metal strip 5c sufficiently thin to be foldable.

Le profilé 4 peut ainsi être plié facilement à angle droit au voisinage d'un coin du vitrage 1, comme indiqué sur la figure 3.The profile 4 can thus be folded easily at a right angle in the vicinity of a corner of the glazing 1, as indicated in FIG. 3.

La matière plastique du profilé 4 est de préférence en copolymère d'éthylène propylène tel que 1'EPDM qui résiste parfaitement à la température de chauffage de l'élément électriquement résistant 5, tout en étant facilement déformable à la température ambiante. The plastic material of the profile 4 is preferably made of ethylene propylene copolymer such as EPDM which perfectly withstands the heating temperature of the electrically resistant element 5, while being easily deformable at room temperature.

Le cordon 7 peut être en une ou plusieurs des résines thermofusibles suivantes:
les résines polyuréthanes à base de polycaprolactone;
les résines à base de polyéthyl -vinylacétate et/ou de polyéthylène-éthyl-acrylate;
. les résines à base de polyéther-polyamide;
. les caoutchoucs SBR (Styrène Butadiène)
. les caoutchoucs butyl
. les polymères et copolymères séquencés de type 515 SBS.The bead 7 can be in one or more of the following hot-melt resins:
polyurethane resins based on polycaprolactone;
resins based on polyethylvinyl acetate and / or polyethylene ethyl acrylate;
. polyether-polyamide-based resins;
. SBR (Styrene Butadiene) rubbers
. butyl rubbers
. type 515 SBS block polymers and copolymers.

Ces résines, leur mélange, leur assemblage avec d'autres agents d'adhérence, de cohésion, peuvent avantageusement être incorporés à des agents de pontage chimiques et ainsi provoquer après application une réticulation partielle du cordon thermofusible. These resins, their mixture, their assembly with other adhesion and cohesion agents, can advantageously be incorporated into chemical bridging agents and thus cause, after application, partial crosslinking of the hot-melt bead.

Un telle formulation du cordon d'adhésif thermofusible permet d'améliorer notablement la résistance au fluage à chaud de ce cordon. Such a formulation of the bead of hot-melt adhesive makes it possible to significantly improve the resistance to hot creep of this bead.

Bien entendu, l'invention n'est pas limitée aux exemples que l'on vient de décrire et on peut apporter à ceux-ci de nombreuses modifications sans sortir du cadre de l'invention. Of course, the invention is not limited to the examples which have just been described and numerous modifications can be made to them without departing from the scope of the invention.

Ainsi, l'invention peut s'appliquer au collage de tout panneau en verre ou en métal sur un cadre métallique ou non et ce quelle que soit la forme du panneau et du cadre, étant donné que le profilé 4 peut être plié de façon à s'adapter à n'importe quel contour.  Thus, the invention can be applied to the bonding of any glass or metal panel to a metallic frame or not and this regardless of the shape of the panel and of the frame, since the profile 4 can be folded so as to adapt to any contour.
