ABSTRACT:
A method for joining extruded weather strip portions by molding and the resulting weather strip for a motor vehicle. Ends of the extruded weather strip portions, each of which has a trim portion from which a plurality of flange retaining lips project obliquely inwardly, are placed in spaced side by side relation. A core plate having thick portions which are longitudinally spaced apart from each other are inserted into ends of the trim portions of the extruded weather strips so that the thick portions press the flange retaining lips against opposed inner surfaces of the ends of the trim portions, the ends of the extruded weather strip portions together with the core plate are positioned in a cavity of a mold, and a molding material is injected into the cavity of the mold to form a molded joining portion which joins the extruded weather strip portions. Then, the mold is opened and the core plate is removed from the molded joining portion.
