Description

Panneau d'étanchéité, en particulier pour porte de véhicule automobile, et ses moyens de fabrication Sealing panel, in particular for a motor vehicle door, and its manufacturing means
L'invention concerne un panneau d'étanchéité, en particulier pour porte de véhicule automobile ainsi que son procédé et son dispositif de fabrication.The invention relates to a sealing panel, in particular for the door of a motor vehicle, as well as to its manufacturing method and device.
Les panneaux d'étanchéité qui sont destinés à être posés et fixés sur les tôles des portes de véhicule automobile, du côté interne au véhicule, à des fins d'étanchéité et d'insonorisation, comprennent en général au moins une feuille d'une matière plastique compacte ou cellulaire, telle par exemple que du polyéthylène ou du polypropylène, éventuellement associée à un film d'une matière plastique du même type, qui renforce l'étanchéité et 1 ' insonorisation.Sealing panels which are intended to be placed and fixed on the sheets of motor vehicle doors, on the internal side of the vehicle, for sealing and soundproofing purposes, generally comprise at least one sheet of a material compact or cellular plastic, such as for example polyethylene or polypropylene, possibly associated with a film of a plastic material of the same type, which reinforces the sealing and the soundproofing.
Ces panneaux sont thermoformés pour être adaptables aux formes plus ou moins complexes des faces intérieures des portes de véhicule et comportent sur une face un cordon ou un film de matière adhesive qui permet de les fixer par collage sur les tôles des portes.These panels are thermoformed to be adaptable to the more or less complex shapes of the interior faces of vehicle doors and comprise on one side a bead or a film of adhesive material which makes it possible to fix them by gluing on the sheets of the doors.
En général ces panneaux thermoformés sont empilés les uns sur les autres pour être livrés aux constructeurs des véhicules automobiles. Un séparateur tel qu'une feuille de papier siliconé ou analogue est posé soit sur le cordon adhésif de chaque panneau, soit entre deux panneaux empilés pour permettre l'empilage de ces panneaux et leur séparation sans peine.In general, these thermoformed panels are stacked on top of each other to be delivered to the manufacturers of motor vehicles. A separator such as a sheet of silicone paper or the like is placed either on the adhesive bead of each panel, or between two stacked panels to allow the stacking of these panels and their separation without difficulty.
Pour éviter l'utilisation de ces séparateurs, on a déjà proposé d'utiliser des adhésifs du type "hot melt" qui sont déposés à chaud sur les panneaux et qui sont réticulés pour être fortement cohésifs et se détacher facilement des autres panneaux avec lesquels ils sont en contact lors de l'empilage des panneaux. Cela permet d'empiler les panneaux directement sans séparateurs siliconés. En général, ces cordons de matière adhesive, qui sont souvent sous forme de mousse pour s'écraser plus facilement quand ils sont appliqués sur les tôles des portes des véhicules, ont une section circulaire ou approximativement circulaire et sont déposés au pistolet ou au moyen d'un outil à buse le long des bords périphériques des panneaux, le diamètre de ces cordons étant typiquement de l'ordre de 5 à 6 millimètres .To avoid the use of these separators, it has already been proposed to use adhesives of the "hot melt" type which are deposited hot on the panels and which are crosslinked to be highly cohesive and are easily detach from other panels with which they are in contact when stacking the panels. This allows the panels to be stacked directly without silicone separators. In general, these beads of adhesive material, which are often in the form of foam for easier crushing when they are applied to the sheets of vehicle doors, have a circular or approximately circular section and are deposited by spray gun or by means of 'A nozzle tool along the peripheral edges of the panels, the diameter of these beads is typically of the order of 5 to 6 millimeters.
Ces cordons de matière adhesive en mousse ont un inconvénient, qui est leur facilité d'écrasement sur des longueurs plus ou moins importantes lors de leur stockage, de leur transport et de leur manipulation, ce qui peut se traduire par des défauts de collage des panneaux sur les portes de véhicule.These cords of foam adhesive material have a drawback, which is their ease of crushing over varying lengths during their storage, transport and handling, which can result in defects in the bonding of the panels. on vehicle doors.
La présente invention a notamment pour but d'éviter cet inconvénient.The object of the present invention is in particular to avoid this drawback.
Elle propose à cet effet un panneau d'étanchéité du type précité, en particulier pour porte de véhicule automobile, comprenant au moins une feuille d'une matière plastique compacte ou cellulaire et une matière adhesive déposée sur une face du panneau le long d'une partie au moins de sa périphérie. Le panneau d'étanchéité est caractérisé selon l'invention en ce que la matière adhesive est déposée sous forme d'un ruban qui est à section transversale oblongue avec une épaisseur inférieure à sa largeur et qui conserve une largeur sensiblement constante sur toute sa longueur.To this end, it provides a sealing panel of the aforementioned type, in particular for a motor vehicle door, comprising at least one sheet of compact or cellular plastic material and an adhesive material deposited on one face of the panel along a at least part of its periphery. The sealing panel is characterized according to the invention in that the adhesive material is deposited in the form of a tape which is of oblong cross section with a thickness less than its width and which retains a substantially constant width over its entire length.
De préférence, ce ruban est à section sensiblement rectangulaire, ou sensiblement semi- elliptique avec un grand axe parallèle à la surface du panneau et un petit axe perpendiculaire à la surface du panneau.Preferably, this strip is of substantially rectangular section, or substantially semi-elliptical with a major axis parallel to the surface of the panel and a minor axis perpendicular to the surface of the panel.
Cette forme particulière du ruban de matière adhesive réduit beaucoup les risques d'écrasement lors du stockage, du transport ou de la manipulation des panneaux et réduit de façon correspondante les inconvénients résultant de cet écrasement.This particular shape of the tape of adhesive material greatly reduces the risks of crushing during storage, transport or handling of the panels and correspondingly reduces the drawbacks resulting from this crushing.
Par ailleurs, ce ruban est avantageusement en matière adhesive compacte ou sensiblement compacte, ce qui réduit encore ses risques d'écrasement accidentel avant la fixation du panneau sur une porte de véhicule.Furthermore, this tape is advantageously made of compact or substantially compact adhesive material, which further reduces its risk of accidental crushing before the panel is fixed to a vehicle door.
La pose d'un ruban de matière adhesive selon l'invention sur un panneau d'étanchéité, c'est-à-dire selon un trajet qui peut être relativement sinueux, ne peut pas être effectuée directement au moyen des matériels utilisés habituellement, car le dépôt d'un ruban à section rectangulaire le long d'une ligne sinueuse ou brisée nécessiterait de faire tourner autour d'un axe perpendiculaire au panneau les moyens utilisés pour déposer le ruban sur le panneau.The laying of a tape of adhesive material according to the invention on a sealing panel, that is to say along a path which can be relatively winding, cannot be carried out directly by means of the materials normally used, because depositing a rectangular section ribbon along a sinuous or broken line would require rotating the means used to deposit the ribbon on the panel around an axis perpendicular to the panel.
L'invention propose donc également un procédé de fabrication d'un panneau du type décrit ci-dessus, caractérisé en ce qu'il consiste à déposer un ruban de matière adhesive sur le panneau le long d'un tracé prédéterminé, par combinaison d'un mouvement de translation dans le plan du panneau et d'un mouvement de rotation autour d'un axe perpendiculaire au plan du panneau, entre ce panneau et des moyens de dépôt du ruban .The invention therefore also provides a method of manufacturing a panel of the type described above, characterized in that it consists in depositing a tape of adhesive material on the panel along a predetermined path, by combination of a translational movement in the plane of the panel and a rotational movement about an axis perpendicular to the plane of the panel, between this panel and means for depositing the ribbon.
Le dépôt du ruban de matière adhesive est de préférence réalisé par extrusion ou par pulvérisation.The deposition of the tape of adhesive material is preferably carried out by extrusion or by spraying.
Dans un mode de réalisation préféré de l'invention, ce procédé consiste à déplacer le panneau dans son plan par rotation autour d'un axe perpendiculaire au panneau. Il est en effet plus facile de faire tourner le panneau autour d'un axe perpendiculaire que de faire tourner les moyens de dépôt du ruban (tels par exemple que des moyens d' extrusion) autour de cet axe.In a preferred embodiment of the invention, this method consists in moving the panel in its plane by rotation about an axis perpendicular to the panel. It is in fact easier to rotate the panel around a perpendicular axis than to rotate the tape deposition means (such as for example extrusion means) about this axis.
Avantageusement, ce procédé consiste également à déplacer le panneau par translation le long d'au moins un axe parallèle à son plan, et à déplacer les moyens de dépôt du ruban en translation le long d'au moins un autre axe parallèle au panneau.Advantageously, this method also consists in moving the panel by translation along at least one axis parallel to its plane, and in moving the means for depositing the ribbon in translation along at least one other axis parallel to the panel.
La combinaison de ces mouvements de translation et du mouvement de rotation du panneau autour d'un axe perpendiculaire à son plan, permet de déposer un ruban de matière adhesive à section oblongue, par exemple sensiblement rectangulaire sur le panneau en suivant un tracé quelconque, qui peut être plus ou moins sinueux suivant les cas.The combination of these translational movements and the rotational movement of the panel around an axis perpendicular to its plane makes it possible to deposit a strip of adhesive material of oblong section, for example substantially rectangular, on the panel following any path, which can be more or less sinuous depending on the case.
L'invention propose également un dispositif de fabrication d'un panneau du type décrit ci-dessus, ce dispositif comprenant une table de support du panneau et des moyens de dépôt, par exemple par extrusion, d'un ruban de matière adhesive sur le panneau, ce dispositif étant caractérisé en ce qu'il comprend des moyens motorisés de déplacement relatif de ladite table et des moyens de dépôt en rotation autour d'un axe perpendiculaire au panneau et des moyens motorisés de déplacement relatif de la table et des moyens de dépôt en translation le long d'au moins un axe parallèle au panneau.The invention also provides a device for manufacturing a panel of the type described above, this device comprising a panel support table and means for depositing, for example by extrusion, a tape of adhesive material on the panel , this device being characterized in that it comprises motorized means for relative displacement of said table and means for depositing in rotation about an axis perpendicular to the panel and means motorized relative movement of the table and translational depositing means along at least one axis parallel to the panel.
De préférence, ce dispositif comprend des moyens motorisés de déplacement de la table en rotation autour d'un axe perpendiculaire au plan du panneau et en translation le long d'au moins un axe parallèle à ce panneau, et des moyens motorisés de déplacement des moyens de dépôt du ruban en translation le long d'au moins un autre axe parallèle au panneau.Preferably, this device comprises motorized means for moving the table in rotation about an axis perpendicular to the plane of the panel and in translation along at least one axis parallel to this panel, and motorized means for moving the means depositing the tape in translation along at least one other axis parallel to the panel.
Un tel dispositif permet de déposer un ruban de matière adhesive de section quelconque, en particulier oblongue ou sensiblement rectangulaire, sur un panneau en suivant n'importe quel trajet sinueux, et en effectuant ce dépôt de façon rapide et précise .Such a device makes it possible to deposit a tape of adhesive material of any section, in particular oblong or substantially rectangular, on a panel by following any winding path, and by performing this deposition quickly and precisely.
Les moyens motorisés de déplacement de la table et/ou des moyens de dépôt du ruban sont pilotés par des moyens de traitement de l'information, tels qu'un micro-ordinateur du type PC par exemple.The motorized means for moving the table and / or the tape depositing means are controlled by information processing means, such as a PC type microcomputer for example.
De façon générale, en fonction des types de panneau et des applications prévues, l'épaisseur du ruban de matière adhesive déposé sur un panneau peut varier dans une large mesure d'un type de panneau à l'autre et d'une application à l'autre. En particulier, ce ruban peut être formé d'une couche mince d'adhésif, ayant une épaisseur très inférieure à sa largeur, et qui recouvre une part importante de la surface du panneau.In general, depending on the types of panel and the intended applications, the thickness of the tape of adhesive material deposited on a panel can vary to a large extent from one type of panel to another and from application to application. 'other. In particular, this tape can be formed of a thin layer of adhesive, having a thickness much less than its width, and which covers a large part of the surface of the panel.
L'invention sera mieux comprise et d'autres caractéristiques, détails et avantages de celle-ci apparaîtront plus clairement à la lecture de la description qui suit, faite à titre d'exemple en référence aux dessins annexés dans lesquels : - la figure 1 est une vue schématique partielle en coupe d'un panneau d'étanchéité selon l'invention;The invention will be better understood and other characteristics, details and advantages thereof will appear more clearly on reading the description which follows, given by way of example with reference to the appended drawings in which: - Figure 1 is a partial schematic sectional view of a sealing panel according to the invention;
- la figure 2 est une vue partielle de dessus de ce panneau ; - la figure 3 représente schematiquement un dispositif de fabrication d'un panneau selon 1 ' invention.- Figure 2 is a partial top view of this panel; - Figure 3 shows schematically a device for manufacturing a panel according to one invention.
Le panneau 10 selon l'invention, dont un exemple de réalisation est représenté schematiquement aux figures 1 et 2, est un panneau d'étanchéité et d'insonorisation, en particulier pour une porte de véhicule automobile, et comprend au moins une feuille de matière plastique compacte ou cellulaire, en général à cellules fermées, par exemple en polyéthylène ou en propylène, notamment en polypropylène non réticulé, cette feuille pouvant avoir une épaisseur comprise entre 1 et 5 ou 6 mm environ lorsqu'elle est en matière cellulaire, ou une épaisseur comprise entre 0,15 et 1 mm environ lorsqu'elle en matière compacte.The panel 10 according to the invention, an exemplary embodiment of which is shown diagrammatically in FIGS. 1 and 2, is a sealing and soundproofing panel, in particular for a door of a motor vehicle, and comprises at least one sheet of material compact or cellular plastic, generally with closed cells, for example made of polyethylene or propylene, in particular of non-crosslinked polypropylene, this sheet being able to have a thickness of between 1 and 5 or 6 mm approximately when it is made of cellular material, or a thickness between 0.15 and 1 mm approximately when made of compact material.
Eventuellement, cette feuille 10 est associée à une autre feuille ou à un film de matière plastique du même type ou d'un type analogue, qui est fixé sur la feuille 10 par tout moyen approprié connu dans la technique.Optionally, this sheet 10 is associated with another sheet or with a plastic film of the same type or of a similar type, which is fixed to the sheet 10 by any suitable means known in the art.
Le panneau 10 est en général thermoformé et comporte des parties 12 en creux et/ou en saillie, pour une bonne adaptation aux formes de la face interne de la porte qu'il doit recouvrir, et pour amélioration de ses performances d'insonorisation et éventuellement d'isolation thermique.The panel 10 is generally thermoformed and has recessed and / or projecting parts 12, for a good adaptation to the shapes of the internal face of the door which it must cover, and for improving its soundproofing performance and possibly thermal insulation.
La fixation du panneau 10 sur la tôle d'une porte est assurée au moyen d'un ruban 14 de matière adhesive, qui est déposé sur la face 16 du panneau 10 destinée à être appliquée sur la tôle de la porte, le ruban 14 s 'étendant de façon continue ou discontinue le long de la périphérie de ce panneau.The fixing of the panel 10 on the sheet of a door is ensured by means of a tape 14 of adhesive material, which is deposited on the face 16 of the panel 10 intended to be applied to the sheet of the door, the strip 14 extending continuously or discontinuously along the periphery of this panel.
Le ruban 14 de matière adhesive est à section oblongue ou sensiblement rectangulaire comme représenté aux figures et est avantageusement en matière compacte ou sensiblement compacte, c'est-à- dire très peu cellularisée.The tape 14 of adhesive material is of oblong or substantially rectangular section as shown in the figures and is advantageously made of compact or substantially compact material, that is to say very little cellularized.
L'aire de la section du ruban 14 peut être sensiblement la même que dans la technique antérieure où l'on utilise en général des cordons à section sensiblement circulaire d'un diamètre de l'ordre de 5 à 6 mm. Le ruban 14 selon l'invention peut donc avoir une largeur de 6 à 8 mm par exemple, et une épaisseur de 3 à 4 mm.The cross-sectional area of the ribbon 14 may be substantially the same as in the prior art, where cords with a substantially circular section are generally used, with a diameter of the order of 5 to 6 mm. The tape 14 according to the invention can therefore have a width of 6 to 8 mm for example, and a thickness of 3 to 4 mm.
Le ruban est par exemple à base de matière acrylique en solution aqueuse ou dans un solvant organique, qui peut être plus ou moins réticulée et est de préférence du type "hot melt", c'est-à-dire qui est déposée à chaud sur la feuille 10 pour bien adhérer à celle-ci.The tape is for example based on acrylic material in aqueous solution or in an organic solvent, which can be more or less crosslinked and is preferably of the "hot melt" type, that is to say which is deposited hot on sheet 10 to adhere well thereto.
Bien entendu, la section du ruban 14 selon l'invention peut avoir toute forme oblongue avec une largeur supérieure à son épaisseur, cette largeur étant par exemple 1,5 à 2,5 fois plus grande que l'épaisseur du ruban. La forme de ce ruban en section peut être rectangulaire, ovale, semi-elliptique ou analogue.Of course, the section of the ribbon 14 according to the invention can have any oblong shape with a width greater than its thickness, this width being for example 1.5 to 2.5 times greater than the thickness of the ribbon. The shape of this ribbon in section can be rectangular, oval, semi-elliptical or the like.
Le dépôt du ruban 14 sur la feuille 10 selon un trajet tel que celui représenté en figure 2, nécessite d'orienter une buse d' extrusion ou une tête de dépôt par rotation autour d'un axe perpendiculaire à la feuille 10, lorsqu'on arrive à un coude 18 de ce trajet, de façon à ce que le ruban 14 déposé sur la feuille 10 conserve une largeur sensiblement constante, y compris constante, sur toute sa longueur .The deposition of the ribbon 14 on the sheet 10 along a path such as that shown in Figure 2, requires orienting an extrusion nozzle or a deposition head by rotation about an axis perpendicular to the sheet 10, when arrives at a bend 18 in this path, so that the ribbon 14 deposited on the sheet 10 retains a width substantially constant, including constant, over its entire length.
Le panneau 10 est de préférence thermoformé, puis posé sur une table 20 qui est montée à rotation autour d'un axe vertical 22 et qui est guidée en rotation autour de cet axe par exemple dans un cadre 24 déplaçable lui-même en translation dans un plan horizontal sur des moyens de guidage appropriés.The panel 10 is preferably thermoformed, then placed on a table 20 which is rotatably mounted around a vertical axis 22 and which is guided in rotation about this axis for example in a frame 24 which can itself be displaced in translation in a horizontal plane on suitable guide means.
Des moyens motorisés 26, 28 sont prévus pour déplacer la table 20 en rotation autour de l'axe 22 dans les deux sens et pour déplacer en translation le cadre 24. La périphérie d'un panneau 10 posé sur la table 20 se trouve sous une buse 30 de sortie d'une filière d' extrusion 32, prévue pour déposer sur la face supérieure 16 du panneau 10 un ruban plat 14 de matière adhesive.Motorized means 26, 28 are provided to move the table 20 in rotation about the axis 22 in both directions and to move the frame 24 in translation. The periphery of a panel 10 placed on the table 20 is located under a nozzle 30 for exit from an extrusion die 32, designed to deposit on the upper face 16 of the panel 10 a flat tape 14 of adhesive material.
Dans un mode de réalisation particulier de l'invention, le cadre 24 portant la table 20 est déplaçable en translation le long d'un axe horizontal 34 par les moyens motorisés 28 et les moyens d' extrusion 32 sont déplaçables en translation le long d'un autre axe horizontal 36 perpendiculaire à l'axe 34 précité par des moyens motorisés 38. Cela permet notamment de combiner les déplacements en translation du cadre 24 et des moyens d' extrusion 32 pour le dépôt du ruban 14 de matière adhesive le long de tout trajet souhaité sur le panneau 10.In a particular embodiment of the invention, the frame 24 carrying the table 20 is movable in translation along a horizontal axis 34 by the motorized means 28 and the extrusion means 32 are movable in translation along another horizontal axis 36 perpendicular to the aforementioned axis 34 by motorized means 38. This makes it possible in particular to combine the movements in translation of the frame 24 and of the extrusion means 32 for depositing the tape 14 of adhesive material along any desired route on panel 10.
On peut aussi, en variante, prévoir des moyens motorisés permettant de déplacer le cadre 24 le long de deux axes horizontaux perpendiculaires entre eux, pour faire défiler sous la buse d' extrusion 30 la partie du panneau 10 destinée à recevoir le ruban 14 de matière adhesive, tout en conservant une possibilité de déplacement en translation horizontale des moyens d' extrusion 32, pour superposer de petits mouvements de translation des moyens d' extrusion 32 à de grands mouvements de translation du cadre 24 et accélérer le dépôt du ruban 14 sur le panneau 10 tout en améliorant la précision de ce dépôt.One can also, as a variant, provide motorized means making it possible to move the frame 24 along two horizontal axes perpendicular to one another, to make the part of the panel 10 intended to receive the ribbon 14 of material pass under the extrusion nozzle 30 adhesive, while retaining the possibility of displacement in horizontal translation extrusion means 32, for superimposing small translational movements of the extrusion means 32 on large translational movements of the frame 24 and accelerating the deposition of the tape 14 on the panel 10 while improving the precision of this deposition.
Les moyens motorisés 26, 28, 38 précités de déplacement de la table 20 en rotation, et du cadre 24 et des moyens d' extrusion 32 en translation, sont pilotés par des moyens 40 de traitement de l'information, du type micro-ordinateur par exemple, qui ont été préalablement programmés en fonction du trajet sur lequel le ruban 14 est déposé sur la table 20. Les déplacements en rotation de la table 20 autour de l'axe 22, combinés aux déplacements en translation du cadre 24 et des moyens d' extrusion 32, permettent d'orienter correctement à tout moment la buse d' extrusion 30 par rapport à la direction dans laquelle s'étend le ruban 14 de matière adhesive, et de suivre avec précision les coudes 18 du trajet de ce ruban, tout en conservant une largeur prédéterminée du ruban 14 sensiblement constante, y compris constante, sur toute sa longueur.The aforementioned motorized means 26, 28, 38 for moving the table 20 in rotation, and the frame 24 and the extrusion means 32 in translation, are controlled by means 40 for processing information, of the microcomputer type. for example, which have been previously programmed as a function of the path on which the ribbon 14 is deposited on the table 20. The rotational displacements of the table 20 around the axis 22, combined with the translational displacements of the frame 24 and the means extrusion 32, make it possible to correctly orient the extrusion nozzle 30 at all times relative to the direction in which the tape 14 of adhesive material extends, and to precisely follow the elbows 18 of the path of this tape, while maintaining a predetermined width of the ribbon 14 which is substantially constant, including constant, over its entire length.
Il est avantageux également de prévoir des moyens permettant de compenser au moins partiellement une obliquité, par rapport au plan du panneau, de la partie du panneau sur laquelle on dépose le ruban 14, pour éviter que la matière adhesive qui vient d'être extrudée ou pulvérisée, coule vers le bas sur cette partie oblique. On peut pour cela monter le panneau ou les moyens de support du panneau en rotation autour d'au moins un et de préférence autour de deux axes parallèles à son plan, et de commander l'inclinaison du panneau autour de ces axes ou autour d'un centre de rotation pour que la partie sur laquelle on dépose le ruban 14 soit toujours approximativement horizontale.It is also advantageous to provide means making it possible to at least partially compensate for an obliquity, with respect to the plane of the panel, of the part of the panel on which the tape 14 is deposited, to prevent the adhesive material which has just been extruded or sprayed, flows down over this oblique part. It is possible for this to mount the panel or the means for supporting the panel in rotation about at least one and preferably around two axes parallel to its plane, and to control the inclination of the panel around these axes or around a center of rotation so that the part on which the ribbon 14 is deposited is always approximately horizontal.
Grâce à sa forme particulière et à la compacité de sa matière adhesive, le ruban 14 ne risque pas d'être écrasé pendant le stockage, le transport et la manipulation des panneaux, de sorte qu'un panneau 10 comportant un ruban 14 de matière adhesive selon l'invention peut être posé sans difficulté et sans défaut de collage sur la tôle d'une porte de véhicule automobile.Thanks to its particular shape and to the compactness of its adhesive material, the tape 14 does not risk being crushed during the storage, transport and handling of the panels, so that a panel 10 comprising a tape 14 of adhesive material according to the invention can be installed without difficulty and without bonding defect on the sheet of a motor vehicle door.
Pour leur stockage, les panneaux 10 selon l'invention peuvent être empilés les uns sur les autres, directement ou en utilisant si nécessaire des séparateurs siliconés ou analogues, selon la nature de la matière adhesive utilisée pour former les rubans 14. Lorsque cette matière est très cohesive en raison de sa réticulation, et quand elle a été déposée à chaud sur le panneau 10 et y adhère fortement, il devient en général possible d'empiler les panneaux les uns sur les autres directement, sans séparateurs intermédiaires, et de les séparer ensuite facilement les uns des autres pour leur utilisation, le ruban adhésif 14 d'un panneau n'adhérant que faiblement à l'autre panneau de la pile avec lequel il est contact et pouvant en être séparé sans dégradation ni détérioration. For their storage, the panels 10 according to the invention can be stacked on top of each other, directly or by using silicone separators or the like if necessary, depending on the nature of the adhesive material used to form the tapes 14. When this material is very cohesive due to its crosslinking, and when it has been hot deposited on the panel 10 and strongly adheres to it, it generally becomes possible to stack the panels on top of each other directly, without intermediate separators, and to separate them then easily from one another for their use, the adhesive tape 14 of a panel adhering only weakly to the other panel of the stack with which it is in contact and being able to be separated therefrom without degradation or deterioration.
