COLD-BENDING OF LAMINATED GLAZING

摘要

The invention relates to a method for preparing bent glazing modules comprising a metal frame and a panel comprising a laminated glazing comprising glass substrates separated by a sheet of polymer material, said panel being bent after assembly of the laminated glazing by a force causing said panel to take the shape of the metal frame, then maintained in this shape by a maintaining means, said bending being performed whilst the sheet is at a temperature in the range of 30 to 80°C. The invention reduces the forces required for bending and the shearing stress between the sheet in polymer material and the glass substrates, thereby reducing the risk of delamination.
