Abstract
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.
