PROCEDE DE FABRICATION D’UN VITRAGE FEUILLETE DONT UNE SEULE FEUILLE DE VERRE PRESENTE UN TROU TRAVERSANTPROCESS FOR THE MANUFACTURE OF A LAMINATED GLAZING OF WHICH ONLY ONE SHEET OF GLASS HAS A THROUGH HOLE
La présente invention a trait à un vitrage feuilleté dont l’une seulement des feuilles de verre constitutive présente un trou traversant.The present invention relates to laminated glazing in which only one of the constituent glass sheets has a through hole.
Un vitrage feuilleté comporte au moins deux feuilles de verre collées l’une à l’autre par une couche adhésive intercalaire, telle que polyvinylbutyral.Laminated glazing comprises at least two sheets of glass glued to each other by an intermediate adhesive layer, such as polyvinyl butyral.
L’une seulement de ces deux feuilles de verre peut présenter un trou traversant : soit on retire alors la couche adhésive intercalaire à l’emplacement du trou et les fonctions liées à la sécurité ne sont plus garanties (les propriétés mécaniques, telles qu’attestées par essais de chute de bille -en anglais « bail drop »- sont insuffisantes), soit on laisse la couche adhésive intercalaire à cet emplacement et elle va se dégrader ou fluer à la fabrication du vitrage feuilleté ou à température élevée, et la résistance du vitrage au vieillissement dans les conditions d’utilisation, à température élevée et/ou taux d’humidité élevé, ou à un essai à haute température telle que 120 °C, sera insuffisante.Only one of these two sheets of glass may have a through hole: either the intermediate adhesive layer is then removed at the location of the hole and the safety-related functions are no longer guaranteed (the mechanical properties, as attested by ball drop tests - in English "bail drop" - are insufficient), either leave the adhesive interlayer at this location and it will degrade or creep during the manufacture of laminated or high temperature glazing, and the resistance of the glazing with aging under conditions of use, at high temperature and / or high humidity, or at a test at high temperature such as 120 ° C., will be insufficient.
L’invention a pour but de garantir l’intégrité d’un vitrage feuilleté dont une feuille de verre a un trou traversant, pendant son procédé de fabrication, et d’augmenter sa résistance au vieillissement dans les conditions les plus exigeantes.The object of the invention is to guarantee the integrity of laminated glazing, a glass sheet of which has a through hole, during its manufacturing process, and to increase its resistance to aging under the most demanding conditions.
Ce but est atteint par l’invention, qui en conséquence a pour objet un procédé de fabrication d’un vitrage feuilleté comprenant une première feuille de verre et une seconde feuille de verre collées l’une à l’autre par l’intermédiaire d’une couche adhésive intercalaire, dans lequel la seconde feuille de verre présente un trou traversant, caractérisé en ce qu’il comprend une opération de dégazage pendant laquelle un bouchon est maintenu dans le trou traversant de manière à en occuper le volume, c’est-à-dire une majeure partie du volume, de préférence l’essentiel, la quasi-totalité ou la totalité du volume.This object is achieved by the invention, which consequently relates to a method of manufacturing a laminated glazing comprising a first sheet of glass and a second sheet of glass bonded to one another by means of an intermediate adhesive layer, in which the second glass sheet has a through hole, characterized in that it comprises a degassing operation during which a plug is held in the through hole so as to occupy its volume, that is to say i.e. a major part of the volume, preferably the essential, almost all or all of the volume.
On entend ici essentiellement par « feuille de verre » une feuille de matériau verrier minéral tel que verre notamment silicosodocalcique flotté, borosilicate, aluminosilicate, vitrocéramique, mais aussi organique tel que polycarbonate, poly(méthacrylate de méthyle), résine ionomère.The term “glass sheet” essentially means here a sheet of mineral glass material such as float glass, in particular silico-calcium float glass, borosilicate, aluminosilicate, vitroceramic, but also organic such as polycarbonate, poly (methyl methacrylate), ionomer resin.
La couche adhésive intercalaire est essentiellement constituée de polyvinylbutyral, copolymère éthylène - acétate de vinyle, ou polyuréthane thermoplastique.The intermediate adhesive layer consists essentially of polyvinyl butyral, ethylene-vinyl acetate copolymer, or thermoplastic polyurethane.
Le dégazage consiste à éliminer de la couche adhésive intercalaire et de 5 ses interfaces avec les deux feuilles de verre le gaz -essentiellement de l’airqui y est dissous ou emprisonné, par des techniques qui seront citées plus en détail ci-après. Cette opération est préalable à l’application d’une température relativement élevée, associée le cas échéant à une pression supérieure à l’atmosphérique ou un pressage, qui permet de coller les constituants les uns îo avec les autres.Degassing consists in eliminating from the intermediate adhesive layer and from its interfaces with the two glass sheets the gas, essentially air which is dissolved or trapped therein, by techniques which will be mentioned in more detail below. This operation is prior to the application of a relatively high temperature, associated if necessary with a pressure higher than the atmospheric or a pressing, which makes it possible to bond the constituents with each other.
Grâce à l’invention, le bouchon dans le trou traversant pendant le dégazage garantit le bon maintien en place de la couche adhésive intercalaire, son absence de déformation en particulier en direction du trou traversant. Finalement, la qualité du feuilletage est optimale, les propriétés mécaniques du vitrage feuilleté telles qu’attestées par essais de chute de bille, sont améliorées. La tenue au vieillissement en température et humidité est bonne.Thanks to the invention, the plug in the through hole during degassing guarantees that the intermediate adhesive layer is held in place, its absence of deformation, in particular in the direction of the through hole. Finally, the quality of the laminating is optimal, the mechanical properties of the laminated glazing as attested by ball drop tests, are improved. The resistance to aging in temperature and humidity is good.
Dans une première variante principale du procédé de l’invention, le dégazage met en oeuvre un calandrage en l’absence d’aspiration. On entend ici par « calandrage » le pressage des constituants du vitrage feuilleté entre des rouleaux pour éliminer les gaz dissous dans la couche adhésive intercalaire ou emprisonnés entre les constituants du vitrage feuilleté. Le terme « aspiration » désigne l’application d’une pression inférieure à la pression atmosphérique, d’un vide primaire (trompe à eau) ou non. Selon des caractéristiques préférées de cette première variante principale :In a first main variant of the process of the invention, degassing implements calendering in the absence of suction. The term “calendering” is understood here to mean pressing the constituents of the laminated glazing between rollers to eliminate the gases dissolved in the intermediate adhesive layer or trapped between the constituents of the laminated glazing. The term "suction" designates the application of a pressure below atmospheric pressure, a primary vacuum (water pump) or not. According to preferred characteristics of this first main variant:
- le bouchon est maintenu dans le trou traversant par une bande adhésive sur la surface de la seconde feuille de verre opposée à la couche adhésive intercalaire, le bouchon affleure à cette surface et n’est pas en adhésion avec la couche adhésive intercalaire pendant le dégazage ; en particulier, un film non adhérent, en poly(tétrafluoroéthylène) ou équivalent, est intercalé entre le bouchon et la couche adhésive intercalaire ;- the plug is held in the through hole by an adhesive strip on the surface of the second glass sheet opposite the interlayer adhesive layer, the plug is flush with this surface and is not in adhesion with the interlayer adhesive layer during degassing ; in particular, a non-adherent film, made of poly (tetrafluoroethylene) or equivalent, is interposed between the stopper and the intermediate adhesive layer;
- le bouchon présente un épaulement à l’interface de la couche adhésive intercalaire et de la seconde feuille de verre, l’épaulement est apte à maintenir le bouchon dans le trou traversant, et le bouchon comporte un corps qui affleure à la surface de la seconde feuille de verre opposée à la couche adhésive intercalaire. La couche adhésive intercalaire peut être soumise à un étirement/amincissement local sur sa surface en contact avec ledit épaulement pour compenser l’épaisseur de celui-ci.the stopper has a shoulder at the interface of the intermediate adhesive layer and of the second glass sheet, the shoulder is capable of holding the stopper in the through hole, and the stopper has a body which is flush with the surface of the second sheet of glass opposite the intermediate adhesive layer. The intermediate adhesive layer may be subjected to local stretching / thinning on its surface in contact with said shoulder to compensate for the thickness of the latter.
Dans une seconde variante principale du procédé de l’invention, le dégazage met en œuvre une aspiration, telle que mentionnée ci-dessus : les constituants du vitrage feuilleté sont soumis à une pression inférieure à la pression atmosphérique, un vide primaire ou non, soit par introduction dans une enceinte, un sac hermétique relié à un vide, soit à la périphérie de l’ensemble îo des constituants du feuilleté par la mise en œuvre d’un anneau ou ceinture à vide (connu en anglais sous la désignation « vacuum ring » par exemple) ; ces moyens d’aspiration/vide permettent aussi d’éliminer les gaz dissous et emprisonnés comme déjà décrit. Selon des caractéristiques préférées de cette seconde variante principale :In a second main variant of the process of the invention, the degassing implements a suction, as mentioned above: the constituents of the laminated glazing are subjected to a pressure below atmospheric pressure, a primary vacuum or not, either by introduction into an enclosure, an airtight bag connected to a vacuum, or at the periphery of all the constituents of the laminate by the implementation of a vacuum ring or belt (known in English under the designation "vacuum ring " for example) ; these suction / vacuum means also make it possible to eliminate the dissolved and trapped gases as already described. According to preferred characteristics of this second main variant:
- le bouchon est maintenu avec étanchéité dans le trou traversant par une bande adhésive, une ventouse ou tout autre moyen sur la surface de la seconde feuille de verre opposée à la couche adhésive intercalaire, et le bouchon affleure à cette surface ;- The stopper is held tightly in the through hole by an adhesive strip, a suction cup or any other means on the surface of the second glass sheet opposite the interlayer adhesive layer, and the stopper is flush with this surface;
- le bouchon est maintenu avec étanchéité dans le trou traversant par une bande adhésive, une ventouse ou tout autre moyen sur la surface de la seconde feuille de verre opposée à la couche adhésive intercalaire, et le bouchon n’affleure pas, mais est saillant par rapport à cette surface ;- the stopper is held tightly in the through hole by an adhesive strip, a suction cup or any other means on the surface of the second glass sheet opposite the intermediate adhesive layer, and the stopper is not flush, but is protruding by relation to this surface;
- le bouchon est en liaison étanche avec le trou traversant au moyen d’un joint, et maintenu dans le trou traversant à l’arrêt de l’aspiration, au moyen d’une bande adhésive ou équivalent, sur la surface de la seconde feuille de verre opposée à la couche adhésive intercalaire ;- the plug is in leaktight connection with the through hole by means of a seal, and held in the through hole when the suction stops, by means of an adhesive tape or equivalent, on the surface of the second sheet glass opposite the interlayer adhesive layer;
- une surface périphérique du bouchon est en liaison étanche avec le trou traversant au moyen d’un joint, le bouchon présente un canal reliant l’extérieur du vitrage feuilleté et la couche adhésive intercalaire, le dégazage comprend une aspiration par ledit canal du bouchon, puis après le dégazage, une bande adhésive ou équivalent est collée sur la surface de la seconde feuille de verre de manière à obturer le trou traversant en maintenant le bouchon dans celui-ci ;a peripheral surface of the stopper is in leaktight connection with the through hole by means of a seal, the stopper has a channel connecting the outside of the laminated glazing and the intermediate adhesive layer, the degassing comprises a suction through said stopper channel, then after degassing, an adhesive strip or equivalent is stuck on the surface of the second glass sheet so as to close the through hole while keeping the stopper therein;
- le bouchon présente un épaulement à l’interface de la couche adhésive intercalaire et de la seconde feuille de verre, l’épaulement est apte à maintenir le bouchon dans le trou traversant, et le bouchon comporte un corps ; de préférence, dans cette réalisation, soit la liaison du bouchon au vitrage feuilleté est étanche par l’ajout d’adhésif au niveau dudit épaulement ou dudit corps, soit le bouchon est maintenu avec étanchéité dans le trou traversant par une bande adhésive, une ventouse ou tout autre moyen sur la surface de la seconde feuille de verre opposée à la couche adhésive intercalaire. Comme déjà mentionné ci-dessus, la îo couche adhésive intercalaire peut être soumise à un étirement/amincissement local sur sa surface en contact avec ledit épaulement pour compenser l’épaisseur de celui-ci.- The stopper has a shoulder at the interface of the intermediate adhesive layer and of the second glass sheet, the shoulder is able to hold the stopper in the through hole, and the stopper comprises a body; preferably, in this embodiment, either the connection of the stopper to the laminated glazing is sealed by the addition of adhesive at the level of said shoulder or of said body, or the stopper is held tightly in the through hole by an adhesive strip, a suction cup or any other means on the surface of the second glass sheet opposite the interlayer adhesive layer. As already mentioned above, the intermediate adhesive layer can be subjected to local stretching / thinning on its surface in contact with said shoulder to compensate for the thickness of the latter.
L’invention a également pour objet un vitrage feuilleté obtenu par un procédé tel que décrit ci-dessus, comprenant un bouchon ou une partie restante de celui-ci après en avoir détaché une partie amovible complémentaire et en particulier un tel vitrage feuilleté comprenant un élément connecté à une alimentation électrique, tel que pour l’éclairage, la géolocalisation - navigation, qu’une caméra simple ou double (stéréoscopique), ou un élément fonctionnel sans connexion électrique, élément chaque fois fixé sur le bouchon ou ladite partie restante de celui-ci.The invention also relates to a laminated glazing obtained by a process as described above, comprising a plug or a remaining part of it after having detached a complementary removable part and in particular such laminated glazing comprising an element connected to a power supply, such as for lighting, geolocation - navigation, than a single or double camera (stereoscopic), or a functional element without electrical connection, element each time fixed on the plug or said remaining part of that -this.
L’invention sera mieux comprise à la lumière de la description suivante des représentations schématiques annexées vues en coupe transversale d’un vitrage feuilleté dont l’une seulement des feuilles de verre présente un trou traversant, dans lesquelles :The invention will be better understood in the light of the following description of the appended schematic representations seen in cross section of a laminated glazing of which only one of the sheets of glass has a through hole, in which:
- les Figures 1 et 2 représentent deux variantes de vitrages feuilletés dans leur configuration de dégazage par calandrage en l’absence d’aspiration selon l’invention ;- Figures 1 and 2 show two variants of laminated glazing in their degassing configuration by calendering in the absence of suction according to the invention;
- les Figures 3 et 4 représentent deux variantes d’un vitrage feuilleté avec son élément fonctionnel obtenu à partir du produit intermédiaire de la- Figures 3 and 4 show two variants of a laminated glazing with its functional element obtained from the intermediate product of the
Figure 2; etFigure 2; and
- les Figures 5 à 8 représentent quatre variantes de vitrages feuilletés dans leur configuration de dégazage par aspiration selon l’invention.- Figures 5 to 8 show four variants of laminated glazing in their vacuum degassing configuration according to the invention.
En référence à l’ensemble des Figures, un vitrage feuilleté 10 est constitué d’une première feuille de verre 1 et d’une seconde feuille de verre 3 collées l’une à l’autre par l’intermédiaire d’une couche adhésive intercalaire 2 de polyvinylbutyral (PVB). Seule la seconde feuille de verre 3 présente un trou traversant 4.With reference to all of the Figures, a laminated glazing 10 consists of a first glass sheet 1 and a second glass sheet 3 bonded to each other by means of an intermediate adhesive layer 2 of polyvinyl butyral (PVB). Only the second glass sheet 3 has a through hole 4.
En référence à la Figure 1, le bouchon 5 est maintenu dans le trou traversant 4 par une bande adhésive 11 sur la surface de la seconde feuille de verre 3 opposée à la couche adhésive intercalaire 2, le bouchon 5 affleure à cette surface et n’est pas en adhésion avec la couche adhésive intercalaire 2 îo pendant le dégazage par calandrage. Du fait que le bouchon 5 affleure à la fois aux deux faces principales de la seconde feuille de verre 3, les rouleaux de calandrage peuvent presser efficacement les constituants du feuilleté, c’est-àdire en extraire le gaz, sans dégrader ni déformer la surface du PVB 2.With reference to FIG. 1, the plug 5 is held in the through hole 4 by an adhesive strip 11 on the surface of the second glass sheet 3 opposite the intermediate adhesive layer 2, the plug 5 is flush with this surface and does not is not in adhesion with the intermediate adhesive layer 2 during the degassing by calendering. Because the plug 5 is flush with both the two main faces of the second glass sheet 3, the calendering rollers can effectively press the components of the laminate, that is to say extract the gas therefrom, without degrading or deforming the surface PVB 2.
L’étape suivante du procédé de fabrication du vitrage feuilleté 10 15 comprend un chauffage en autoclave, par exemple à 100 - 120 °C. Le bouchon 5 occupant tout le volume du trou traversant 4, le PVB ne se déforme pas dans l’autoclave en direction du trou traversant 4, en fluant.The next step in the manufacturing process for laminated glazing 10 15 comprises heating in an autoclave, for example at 100 - 120 ° C. The plug 5 occupying the entire volume of the through hole 4, the PVB does not deform in the autoclave in the direction of the through hole 4, while flowing.
A la fin du procédé de fabrication du vitrage feuilleté 10, la bande adhésive 11 et le bouchon 5 sont retirés.At the end of the process for manufacturing the laminated glazing 10, the adhesive strip 11 and the plug 5 are removed.
La bande adhésive 11 est du type résistante à des températures jusqu’àThe adhesive strip 11 is of the type resistant to temperatures up to
260 °C, notamment une bande adhésive en silicone sur base polyimide telle que commercialisée par la Société 3M sous la marque enregistrée Kapton®.260 ° C, in particular a silicone adhesive strip on a polyimide base as sold by the company 3M under the registered trademark Kapton®.
En référence à la Figure 2, le bouchon 6 présente un épaulement 6a à l’interface de la couche de PVB 2 et de la seconde feuille de verre 3, l’épaulement 6a est apte à maintenir le bouchon 6 dans le trou traversant 4, et le bouchon 6 comporte un corps 6b qui affleure à la surface de la seconde feuille de verre 3 opposée à la couche adhésive intercalaire 2; il est donc adapté au dégazage par calandrage comme le bouchon 5 décrit précédemment.With reference to FIG. 2, the plug 6 has a shoulder 6a at the interface of the PVB layer 2 and the second glass sheet 3, the shoulder 6a is able to hold the plug 6 in the through hole 4, and the stopper 6 comprises a body 6b which is flush with the surface of the second glass sheet 3 opposite the intermediate adhesive layer 2; it is therefore suitable for degassing by calendering like the plug 5 described above.
En référence aux Figures 3 et 4, un élément fonctionnel 12 est fixé sur le bouchon 6. Cet élément fonctionnel 12 peut-être relié ou non à une alimentation électrique par l’intermédiaire d’un réseau de fils électroconducteurs noyés dans la couche de PVB 2, ou bien d’une couche électroconductrice formée sur une surface de la première ou la seconde feuille de verre 1, 3. Ces fils, cette couche électroconducteurs sont eux-mêmes reliés à une alimentation électrique via des collecteurs, bus-bars ou équivalent.With reference to FIGS. 3 and 4, a functional element 12 is fixed to the plug 6. This functional element 12 may or may not be connected to an electrical supply via a network of electrically conductive wires embedded in the layer of PVB 2, or else an electrically conductive layer formed on a surface of the first or second glass sheet 1, 3. These wires, this electrically conductive layer are themselves connected to an electrical supply via collectors, bus-bars or the like. .
Par rapport au produit intermédiaire de la Figure 2, dans sa configuration prête au dégazage par calandrage, l’élément fonctionnel 12 de la Figure 4 est fixé sur le bouchon 6 complet de la Figure 2, tandis que celui de la Figure 3 ne l’est que sur l’épaulement 6a, après démontage du corps 6b amovible du bouchon 6.Compared to the intermediate product of Figure 2, in its configuration ready for degassing by calendering, the functional element 12 of Figure 4 is fixed on the plug 6 complete of Figure 2, while that of Figure 3 does not is that on the shoulder 6a, after disassembly of the removable body 6b from the plug 6.
Selon la deuxième variante principale du procédé de l’invention, dont il sera exclusivement question dans la suite de ce commentaire des Figures, le îo dégazage est effectué par aspiration soit par introduction des constituants du vitrage feuilleté 10 dans une enceinte sous pression réduite / vide, soit par aspiration périphérique au moyen d’un anneau ou ceinture d’aspiration (connu en anglais sous les termes de « vacuum ring » par exemple).According to the second main variant of the process of the invention, which will be dealt with exclusively in the rest of this commentary to the Figures, the degassing is carried out by suction or by introduction of the constituents of the laminated glazing 10 into an enclosure under reduced pressure / vacuum , or by peripheral aspiration by means of a suction ring or belt (known in English under the terms of “vacuum ring” for example).
Il doit être noté que le vitrage feuilleté intermédiaire de la Figure 1 peut 15 être soumis également à un dégazage par aspiration, à condition que la bande adhésive 11 soit étanche.It should be noted that the intermediate laminated glazing of Figure 1 may also be subjected to vacuum degassing, provided that the adhesive strip 11 is waterproof.
En référence à la Figure 5, le bouchon 7 est maintenu avec étanchéité dans le trou traversant 4 par une bande adhésive 11, une ventouse ou tout autre moyen sur la surface de la seconde feuille de verre 3 opposée à la couche de PVB 2, et le bouchon 7 n’affleure pas, mais est saillant par rapport à cette surface.With reference to FIG. 5, the plug 7 is held tightly in the through hole 4 by an adhesive strip 11, a suction cup or any other means on the surface of the second glass sheet 3 opposite the layer of PVB 2, and the plug 7 is not flush, but is projecting relative to this surface.
Sur la Figure 6, le bouchon 5 est en liaison étanche avec le trou traversant 4 au moyen d’un joint 13, et maintenu dans le trou traversant 4 à l’arrêt de l’aspiration, au moyen d’une bande adhésive 11 ou équivalent, sur la surface de la seconde feuille de verre 3 opposée à la couche de PVB 2. En effet, en l’absence de la bande adhésive 11, le PVB 2 pourrait avoir tendance à se déformer en direction du trou traversant 4 lorsque l’on arrête de tirer le vide à la périphérie de l’ensemble des constituantsl, 2 et 3, puis à fluer selon cette déformation dans l’étape suivante en autoclave.In FIG. 6, the plug 5 is in leaktight connection with the through hole 4 by means of a seal 13, and held in the through hole 4 when the suction stops, by means of an adhesive strip 11 or equivalent, on the surface of the second glass sheet 3 opposite the layer of PVB 2. Indeed, in the absence of the adhesive strip 11, the PVB 2 could tend to deform in the direction of the through hole 4 when the 'We stop drawing the vacuum at the periphery of all the constituents 1, 2 and 3, then creep according to this deformation in the next step in an autoclave.
Sur la Figure 7, une surface périphérique du bouchon 8 est en liaison étanche avec le trou traversant 4 au moyen d’un joint 13, le bouchon 8 présente un canal reliant l’extérieur du vitrage feuilleté 10 et la couche adhésive intercalaire 2, le dégazage comprend une aspiration par ledit canal du bouchon 8, puis après le dégazage, une bande adhésive 11 ou équivalent (non représentée) est collée sur la surface de la seconde feuille de verre 3 de manière à obturer le trou traversant 4 en maintenant le bouchon 8 dans celui-ciIn FIG. 7, a peripheral surface of the plug 8 is in leaktight connection with the through hole 4 by means of a seal 13, the plug 8 has a channel connecting the outside of the laminated glazing 10 and the intermediate adhesive layer 2, the degassing comprises suction through said channel of the plug 8, then after degassing, an adhesive strip 11 or equivalent (not shown) is bonded to the surface of the second glass sheet 3 so as to close the through hole 4 while maintaining the plug 8 in this one
4. La bande adhésive 11 permet d’éviter le fluage du PVB dans l’étape suivante de fabrication en autoclave.4. The adhesive strip 11 makes it possible to prevent the creep of the PVB in the following autoclave manufacturing step.
En référence à la Figure 8, le bouchon 6 présente un épaulement 6a à l’interface de la couche adhésive intercalaire 2 et de la seconde feuille de verre 3, l’épaulement 6a est apte à maintenir le bouchon 6 dans le trou traversant 4, et le bouchon 6 comporte un corps 6b. Mais à la différence du vitrage feuilleté intermédiaire 10 de la Figure 2, celui 10 de la Figure 8 doit nécessairement îo avoir, dans la mise en œuvre d’un dégazage par aspiration, une liaison étanche du bouchon 6 au vitrage feuilleté intermédiaire 10. Cette liaison étanche peut être procurée par l’ajout d’adhésif au niveau de l’épaulement 6a ou du corps 6b, ou bien encore par une bande adhésive 11, une ventouse ou tout autre moyen sur la surface de la seconde feuille de verre 3 opposée à la couche adhésive intercalaire 2.With reference to FIG. 8, the plug 6 has a shoulder 6a at the interface of the intermediate adhesive layer 2 and of the second glass sheet 3, the shoulder 6a is capable of holding the plug 6 in the through hole 4, and the plug 6 comprises a body 6b. However, unlike the intermediate laminated glazing 10 of FIG. 2, that 10 of FIG. 8 must necessarily have, in the implementation of a vacuum degassing, a tight connection of the plug 6 to the intermediate laminated glazing 10. This tight connection can be provided by the addition of adhesive at the level of the shoulder 6a or of the body 6b, or alternatively by an adhesive strip 11, a suction cup or any other means on the surface of the opposite second sheet of glass 3 to the intermediate adhesive layer 2.
