Abstract
The present invention generally relates to the mounting of windows in a frame, particularly to the mounting of windows of a vehicle, e.g. an automobile, in the body frame work. The invention provides a method for manufacturing a window ready to be mounted comprising, along its edges, a first profiled bead of adhesive material, already cured and having the general cross section of a U-profile. This first bead is elastic but not plastically deformable. The first bead comprises in its interior a second bead of plastically deformable not yet cured adhesive material consisting of a substance chemically compatible to the material of the first bead. The second bead, serving as the real adhesive material, is protected from environmental influences e.g. by covering it by a protection foil which is removed just prior to mounting the window.
