Patent number: 10427383Abstract: The invention relates to a process for the preparation of bent glazed modules comprising a metal framework and a panel comprising a laminated glazing comprising glass substrates separated by an interlayer made of polymer material, the panel being bent, after the laminated glazing has been assembled, by a force which causes it to take the shape of the metal framework and then held in this shape by a holding means, the bending being carried out while the interlayer is at a temperature between 30 and 80° C. The invention reduces the loads necessary for the bending and also the shear stresses between the interlayer made of polymer material and the glass substrates, which reduces the risks of delamination.Type: GrantFiled: November 13, 2012Date of Patent: October 1, 2019Assignee: SAINT-GOBAIN GLASS FRANCEInventors: Fabien Levasseur, Romain Decourcelle, Christophe Swiderski

Patent number: 10343377Abstract: The invention relates to a glazed module comprising a metal framework and an insulating glazing comprising a water-tight barrier, said insulating glazing being cold-bent, the metal framework and the insulating glazing being rendered integral by a holding means which forces the insulating glazing to retain the bent shape conferred on it by the framework. The invention also relates to a process for the preparation of the glazed module comprising a metal framework and an insulating glazing, the insulating glazing being cold-bent, after it has been assembled with a water-tight barrier, by a force which causes it to take the shape of the metal framework and then held in this bent shape by a holding means.Type: GrantFiled: March 22, 2017Date of Patent: July 9, 2019Assignee: SAINT-GOBAIN GLASS FRANCEInventors: Fabien Levasseur, Romain Decourcelle, Christophe Swiderski
