Abstract
Preparation of a ready-to-assemble glazing intended to be glued in the frame of a window opening of the vehicle body. According to the invention, two adhesive beads (18,15) are deposited, simultaneously or immediately after one another, on glass sheet (1), or on an opaque coating (10) in the shape of a frame adhering to sheet (1). The adhesive compound that forms the first bead (18) is selected or treated so that this bead sets in a relatively short time. The adhesive compound forming the second bead (15) is selected or treated so that this bead (15) remains plastically deformable and adhesive for a sufficient period to be used directly for gluing the glazing in the window opening during its assembly. Adhesive bead (18), which sets in a short time, optionally makes it possible to fasten parts of the structure frame, for example a tearing wire (21), and it advantageously comprises a shaped sealing lip (20).
