Beschreibung
Zusammenfassung:	A method of manufacturing a weather strip 10 includes forming a compressible bulb member 12 having a hollow interior 14. A liquid thermoplastic material 34, such as a hot melt material, is injected into the hollow interior 14. The thermoplastic material 34 cures into a resilient plug 40 to provide reinforcement to one or more locations along the length of the weather strip 10. La présente invention a trait à un procédé de fabrication d'une bande d'étanchéité (10) comprenant la formation d'un organe de type boudin (12) présentant une partie intérieure creuse (14). On injecte un matériau thermoplastique liquide (34), tel qu'un matériau adhésif thermofusible dans la partie intérieure creuse (14). On soumet le matériau thermoplastique (34) à une cuisson qui le transforme en un tampon élastique (40) pour réaliser un renfort d'un ou de plusieurs endroits selon la longueur de la bande d'étanchéité (10).
