An automobile glass pane is provided with a frame molding of a polymer. The molding has a portion with a U-like cross section. In this portion, an adhesive bead is introduced, the bead serves for bonding the glass pane to the attachment flange of the window opening in the vehicle bodywork. The lateral limbs of the U-like portion of the molding are internally provided with anchoring projections for mechanically holding the adhesive bead in place between the limbs without any separate adhesive or bonding.

[ We claim:] [1.] A method for the production of a glass pane assembly suitable for bonding a pane of glass to the attachment flange of a window opening, wherein said glass pane assembly comprises a frame-shape polymer molding arranged along an edge part of the pane with a U-shape portion directed towards the attachment flange, said U-shape portion having an outer surface and a U-shape cross section with lateral limbs defining a cavity with an internal wall surface having anchoring projections for an adhesive bead to be deposited as a bonding material in said portion of U-shape cross section, and wherein the frame-shape polymer molding comprises a thermoplastic polyolefin elastomer of isotactic polypropylene and ethylene-propylene-diene rubber and the cured bonding material comprises a moisture curing single component polyurethane system which does not enter into any adhesive bond with said polymer molding, so as to provide a connection between the polymer molding and the bonding material which is solely mechanical; said method comprising the steps of:a) producing said frame-shape polymer molding in a multi-part mold by injection molding, said mold having two mold parts movable toward each other to define a mold cavity in which said elastomer is injected to form said polymer molding by injection molding, and away from each other to permit removal of said polymer molding, one of said mold parts having a core defining the cavity of said U-shape portion, said core being movably mounted in said one mold part;b) moving said one mold part away from the other after said elastomer is injected into and solidified in said cavity while maintaining said core in the cavity of said U-shape portion of the polymer molding; andc) thereafter removing said core from the cavity of said U-shape portion of the polymer molding.
