The invention concerns a method and a device for forming a uniform adhesive bead in the edges of the partitions of the cells of an alveolar structure (10), which consists in: placing thereon an adhesive film (11) and heating said adhesive film (11) with a source (24) emitting a radiation adapted to the reactivity of the adhesive, so as to only heat the latter selectively, thereby ensuring a flow of the adhesive without substantially polymerising it. The portion of the part located beneath the source is maintained, preferably, substantially horizontal so that the adhesive bead is formed in the best possible conditions.
Pour former un bourrelet de colle régulier sur les bords des cloisons des cellules d'une structure alvéolée (10), on place sur celle-ci un film de colle (11) et on chauffe ce film de colle (11) au moyen d'une source (24) qui émet un rayonnement adapté à la réactivité de la colle, pour ne chauffer sélectivement que celle-ci. On assure ainsi un fluage de la colle sans déclencher sensiblement sa polymérisation. La partie de la pièce située en dessous de la source est maintenue, de préférence, sensiblement horizontale afin que le bourrelet de colle soit formé dans les meilleures conditions possibles.
