Abstract

L'invention vise à fournir un procédé de fabrication de verres feuilletés fonctionnels, un procédé d'agencement d'éléments de verre destinés à des verres feuilletés fonctionnels et un agencement d'éléments de verre destinés à des verres feuilletés fonctionnels, permettant une thermorégulation individuelle ou non homogène dans le même plan, de manière à ce que des éléments fonctionnels en particulier thermiquement sensibles puissent être stratifiés dans le verre feuilleté destiné à un verre feuilleté fonctionnel. À cet effet, l'invention permet en outre d'obtenir un agencement et une association des composants appropriés. L'invention concerne également un procédé de fabrication de verres feuilletés fonctionnels à partir d'un agencement d'éléments de verre (12), au moins une couche stratifiée inférieure (2) étant déposée sur un élément de verre inférieur (1) en tant qu'élément de verre de base (1), de sorte qu'au moins un élément fonctionnel (3) soit agencé de façon espacée du bord de vitre (7) sur la couche stratifiée inférieure (2), qu'au moins une couche stratifiée supérieure (4) soit déposée sur ledit élément fonctionnel (3) et qu'ensuite qu'un élément de verre supérieur (5) soit déposé en tant qu'élément de verre de recouvrement (5), et qu'ensuite une stratification à vide de l'agencement des élément de verre (12) ait lieu, un champ de températures non homogène étant produit lors de la stratification à vide, l'agencement des élément de verre (12) étant thermorégulé à au moins une première température de stratification au moins dans la zone dudit élément fonctionnel (3, 13), et l'agencement des éléments de verre (12) étant thermorégulé à au moins une seconde température de stratification au moins au niveau du bord de vitre (7) ou dans la zone (11) à l'écart dudit élément fonctionnel (3), la première température de stratification étant inférieure à la seconde température de stratification.
