A motor vehicle glazing ( ) prepared for installation according to the adhesive process is provided with a profiled spacer ( ) produced by extrusion of an extrudable polymer directly onto glazing ( ) and subsequent setting. During installation of glazing ( ) in the window opening of the motor vehicle body, profiled spacer ( ) acts as an intermediate member between glazing ( ) and assembly adhesive extrudate ( ). Profiled spacer ( ) is provided along its outer periphery with a lip portion ( ) projecting beyond peripheral area ( ) of glazing ( ). In the installed position of glazing ( ), lip portion ( ) rests against the window frame flange ( ) running parallel to peripheral area ( ) of glazing ( ) and acts, upon insertion of the glazing during the setting process of assembly adhesive ( ), as a support and centering element for glazing ( ).

Method of centering windshield glazings

A motor vehicle glazing (1) prepared for installation according to the adhesive process is provided with a profiled spacer (8) produced by extrusion of an extrudable polymer directly onto glazing (1) and subsequent setting. During installation of glazing (1) in the window opening of the motor vehicle body, profiled spacer (8) acts as an intermediate member between glazing (1) and assembly adhesive extrudate (13). Profiled spacer (8) is provided along its outer periphery with a lip portion (10) projecting beyond peripheral area (3) of glazing (1). In the installed position of glazing (1), lip portion (10) rests against the window frame flange (4) running parallel to peripheral area (3) of glazing (1) and acts, upon insertion of the glazing during the setting process of assembly adhesive (13), as a support and centering element for glazing (1).

Spacer for windshield bracket

A motor vehicle glazing prepared for installation is provided with one or more profiled spacers produced by extrusion of an extrudable polymer directly onto the glazing. A first spacer is provided along its outer periphery with an lip portion projecting beyond the peripheral area of the glazing. In the installed position of the glazing the lip portion rests against the window frame flange running parallel to the peripheral area of the glazing and acts, upon insertion of the glazing and during the setting process of the assembly adhesive, as a support and centering element for the glazing. 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.

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. Any additional flash or tab (41) is cut off along the edge (40) of the lip portion (10) of the spacer.
