Abstract: An apparatus for cambering glass sheets includes a reheating furnace for reheating a glass sheet, a sealed cambering station and a conveyor for transferring a heated glass sheet from the furnace to the cambering station. The cambering station includes a shaping upper member. The glass sheet therein is raised into engagement with the upper member, for example by gas pressure, in order to camber the glass sheet. Hot gas ducts surrounding the upper member blow hot gas onto the upper member in such a way as to increased the temperature thereof to a temperature higher than that of the glass sheet when the glass sheet enters the cambering station. Therefore, the glass sheet can be introduced into the cambering station at a relatively low temperature and heated to a temperature high enough for cambering only when in contact with the upper member. The cambered glass sheet can then be discharged to a cooling station.

Adjacent the first profiled spacer, and attached to the glazing is the assembly adhesive bead. Optionally, a second spacer is provided also adjacent the adhesive bead for retaining the adhesive bead between the first and second spacers and for adding support.

Abstract: An apparatus for production of a continuous plastic sheet (2) includes structure for the forming of at least one layer cast in the liquid state of this plastic material, or a reaction mixture of reactive components, on a mobile support of glass plates (1) placed edge to edge and carried by a conveyor, followed by the setting of the layer formed on the surface of the glass plates and pulling off the set sheet. Strips (3) of flexible material are inserted between the adjacent glass plates. The adjacent edges of the glass plates are covered, before the casting is performed, by a ribbon (4) of a material nonadherent to the glass, which overlaps the section of the inserted strip or strips. After having been positioned on the glass plates, the ribbon is made temporarily adherent to the latter upstream from the casting in the liquid state by electrostatically charging with opposite charges the glass plates and the ribbon.

Abstract: In an apparatus for bending glass panes in a horizontal position, comprising an upper bending mold and a lower frame-shaped mold, the bending force exerted by the bending mold is determined by the self-weight of the bending mold. In order that a uniform pressure shall be exerted by the upper bending mold on the entire periphery of the lower frame-shaped mold, the upper bending is mounted displaceable on its guide rods relative to them in a vertical direction and variable in its angular position relative to the guide rods. To achieve the desired relief of weight of the bending mold, the guide rods are suspended by cables from a frame which can be lowered. On the frame, hydraulic or pneumatic cylinders are disposed, which each exert, via a pulling cable acting on a guide rod, an adjustable force in the opposite direction to the self-weight of the bending mold.

Abstract: A method for producing a spacer for a windshield bracket including laying a window glazing (1) on a support frame (15), and guiding an extrusion head along the glazing edge. The extrusion head has an extrusion die (16) with a calibrated opening (18) corresponding to the desired cross-section of the spacer. The extrudable polymer compound for the spacer is fed to the extrusion die (16) by a pipe (19) connected to a feeding and pumping mechanism. The extrusion die (16) is then removed from the glazing (1). The transition zone of the profiled spacer 8 is then subjected to additional compression by operation of upper and lower rams (23, 25), the rams exhibiting forming areas corresponding to the lower and upper forms of the spacer, respectively. Release films 33 and 34 are laid on forming areas of the lower ram (23) and the upper ram (25) prior to the compression molding process. After the compression molding, film pieces 33 and 34 adhere to the polymer material, but do not bond thereto.

Abstract: A motor vehicle glazing prepared for bonding with the window frame of a motor vehicle body is provided with a profile bead and a single tear-away cord. The profile bead serves as an intermediate body between the glazing surface and an assembly adhesive. In the area coming in contact with the assembly adhesive the width of the profile bead is selected to inhibit the lateral overflow of the assembly adhesive over the profile bead during installation. A tear-away cord is placed inside the profile bead or in its immediate vicinity to shear through the profile bead when removing glazing. The profile bead itself or the adhesive bonding of the profile bead to the glazing surface is shaped so that the width of the section of profile bead to be sheared through by the tear-away cord is substantially smaller than the width of the area coming in contact with the assembly adhesive.

Abstract: Glazings are preshaped before putting them through a step of tempering by contact. In a preferred variant, tempering by contact is applied only the central area of the glazing and the marginal zone thereof is tempered by blowing cold air.

Abstract: A window of a double glazing system includes a window frame formed in a wall of a room, a sash fitted in the window frame and an outer glazing mounted in the sash, all of which are conventional. A second glazing is mounted to the sash and at an interior position relative to the outer glazing, so as to form an air circulation space between the second and outer glazings. The second glazing is heated by a transparent electrical resistance layer formed thereon and apertures are formed in the sash to create an air circulation path from the outside, through the air circulation space into the room. As a result, fresh air circulating into the room is heated by the heated second glazing.
