Methods of producing core layers with a variable basis weight across a width of the core layer are described. The core layers can be used in vehicle headliners to permit proper side air bag deployment in the vehicles during crashes. Systems and various materials used to produce the core layers are also described.

    L'invention concerne des procédés de production de couches de noyau ayant un poids de base variable sur une largeur de la couche de noyau. Les couches de noyau peuvent être utilisées dans des garnitures de toit de véhicule pour permettre un déploiement correct du coussin de sécurité gonflable latéral dans les véhicules lors d'accidents.
