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