METHOD FOR JOINING EXTRUDED WEATHER STRIPS AND RESULTING WEATHER STRIP FOR MOTOR VEHICLE

摘要

A method for joining extruded weather strip sections by molding and resulting weather strips for a motor vehicle. Ends of the extruded weather strip sections, each having a trim portion from which a plurality of flange retaining lips project obliquely inwardly, are positioned facing each other. A core plate having portions of increased thickness which are longitudinally spaced apart from one another is inserted into the ends of the trim portions of the extruded weather strip sections, so that the thick portions press the flange retaining lips against the adjacent inner surfaces of the ends of the trim portions. The ends of the extruded weather strip sections 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 ends of the extruded weather strip sections. Then, the mold is opened and the core plate is removed from the molded joining portion.
