ABSTRACT:
An appendage (7) is molded onto a glazing profile (3) provided around the periphery of a pane of glass (2), the process comprising advancing a mold (20) into sealing contact with an appropriate part of the profile, introducing a predetermined quantity of polymer material (39) into a mold cavity (40), and allowing the polymer material to bond to the glazing profile. The pane of glass remains outside the mold cavity, and is preferably not contacted by the mold. The polymer material may be thermosetting or thermoplastic, and is preferably introduced into the mold cavity while the mold is open. The material may be poured if it is in a fluid condition, or, if it is thermoplastic, it may be introduced in the form of a preformed piece (50) which is superficially melted to bond it to the glazing profile. The process is suitable for molding sharp corners onto extruded profiles on vehicle glazings (1).
