Patent

CA 2196949

A pinch welt for trimming a flange formed on a vehicle body panel is disclosed. The welt includes a rigid insert made of a thermoplastic or synthetic rubber material that is compatible with the material of an outer decorative layer of the welt so as to allow the pinch welt to be readily recyclable as a single unit after use. The material of the insert has a resilience that allows the welt to be readily secured to the flange in a resilient manner. The insert is shaped by cooperating continuous forming rolls in an extrusion process that provides oppositely extending tines in which a thin webbing is formed between the tines.

L'invention concerne un ourlet pincé pour la finition d'une bordure formée sur un panneau de carrosserie de véhicule. L'ourlet comprend un élément rapporté rigide en thermoplastique ou en caoutchouc synthétique compatible avec le matériau de la couche décorative extérieure de l'ourlet, de manière à permettre à l'ourlet pincé d'être facilement recyclable, individuellement, après une seule utilisation. Le matériau de l'élément rapporté présente une résilience qui permet de fixer facilement l'ourlet à la bordure, d'une manière résiliente. L'élément rapporté est profilé par des rouleaux couplés de formage en continu, suivant un procédé d'extrusion qui produit des pointes en sens opposé avec sangle de faibles dimensions formée entre les pointes.
