INTERLAYER COMPOSITE STRUCTURE FOR LAMINATED GLASS WITH CONTROLLED BONDING BETWEEN THE LAYERS AND THE PROCESS FOR THE PRODUCTION OF THE INTERLAYER STRUCTURE

A process for the production of multi-ply polyvinyl butyral interlayer having improved separation force whereby multiple plies are combined in a tension controlled process comprising overlaying a layer of PVB sheeting having water drops on its surface with a second layer of PVB sheeting.

Zusammenfassung:	A process for the production of multi-ply polyvinyl butyral interlayer having improved separation force whereby multiple plies are combined in a tension controlled process comprising overlaying a layer of PVB sheeting having water drops on its surface with a second layer of PVB sheeting. La présente invention concerne un processus de production de couche de liaison intercouche multicouche en polybutyral de vinyle qui possède une force de séparation améliorée. Les couches multiples sont associée selon un processus à tension contrôlée qui consiste à superposer une couche de PVB en feuille à la surface de laquelle se trouvent des gouttes d'eau, avec une seconde couche de PVB en feuille.
