Abstract

A technique for factory glazing of glass panes in window frames is provided. Each frame has a pane receiving groove which corresponds in its depth approximately to the thickness of the glass pane. This groove is filled with a pane edge and a hardenable sealing mass. The invention further relates to a process for factory glazing of glass panes, in particular, glass panes which have been individually inserted into a window frame groove that is open or accessible on one side and that corresponds in its depth approximately to the thickness of the glass pane. When such groove is filled with a hardenable sealing mass, the latter is subsequently hardened.

Claims

1. A method for glazing a window frame with a glass pane, said window frame having a groove of a depth substantially equal to the thickness of the window pane, comprising the steps of:

providing the pane-parallel wall of said groove with an elastically deformable, compressible, first sealing profile which projects from the groove, in a direction parallel to the pane;

inserting said glass pane into the window frame with said first sealing profile abutting said glass pane in the installation area of the pane;

filling the space remaining in said groove with a hardenable sealing mass;

covering said groove filled with said hardenable sealing mass with a glass pane retention strip which manifests a second elastically deformable, compressible sealing profile resting against the glass surface opposite the surface facing the groove wall, in the marginal region of the glass pane;

pressing said glass pane in a direction towards said pane-parallel wall, to bias and deform said first and second sealing profiles against said glass pane, providing a continuous seal;

subsequently hardening said sealing mass to maintain the sealing profile in a biased and deformed condition; and

removing the pressure from against said glass pane,

whereby the glass pane and first sealing means remain in a biased relationship as the glass pane is retained in the pressed position by the hardened sealing mass and the glass retaining strip is applied prior to said hardening of the sealing mass, the force pressing said glass pane against said groove wall provided with said first sealing profile is exerted on said glass pane retention strip, and the glass retention strip is cemented by said sealing mass subsequent to its hardening and is fixed with regard to its position.

2. The method of claim 1 wherein said first sealing profile on the groove wall is arranged in proximity of the groove edge.

3. The method of claim 1 wherein said pressing of said glass pane against said groove wall provided with said first sealing profile takes place directly on the glass pane.

4. The method of claim 1 wherein said window frame is horizontally arranged, and that the pressure is applied by a dead weight.

5. The method of claim 1 wherein the pressure of said glass pane against said groove wall is applied by suction stress exerted upon said glass pane.
