The invention concerns a method for making a modular element, such as a motor vehicle roof or door, ready to be bonded onto a frame or other surface with a bonding bead in accordance with a bonding pattern, closed in particular, comprising the following steps: producing, in particular in a mould, a composite shape bonding bead reproducing the bonding pattern and having a specific cross-section, comprising a structural bead linked to a protected adhesive coating or capable of being activated and to the element. The invention also provides producing in a mould a homogeneous bonding bead having at least a protected adhesive surface or capable of being activated. The method for mounting the modular element consists in removing the protection or activating the adhesive coating and in pressing the modular element on the frame or like surface. The invention is applicable to car manufacture.
Selon l'invention, on fabrique un élément modulaire, tel qu'un module de toit ou de portière de véhicule automobile, prêt à être collé sur un cadre ou autre surface au moyen d'un cordon adhésif déposé suivant un motif de collage notamment fermé, de la façon suivante: l'on fabrique, notamment dans un moule, un cordon de collage composite de forme reproduisant le motif de collage et de section déterminée, comprenant un cordon structurel lié, d'une part, à une couche d'adhésif protégé ou activable et, d'autre part, à l'élément. Il est également prévu de fabriquer dans un moule un cordon de collage homogène présentant au moins une face adhésive protégée ou activable. Pour le montage de l'élément modulaire, on retire la protection ou l'on active la couche d'adhésif et l'on applique l'élément modulaire sur le cadre ou autre surface. Application à la fabrication de véhicules automobiles.
