ABSTRACT:
A method for producing a weather strip of which an external surface is covered with a finishing covering layer such as a fabric layer, the weather strip having a sealing portion which is partially formed by using a mold without the damage of the covering layer due to the heat of the mold. The method includes extruding a weather strip having a trim portion, a sealing portion projecting from one side wall of the trim portion, and a lip extending along a border between the trim portion and the sealing portion, covering an external surface of the trim portion of the continuously extruded weather strip with a covering layer continuously, cutting the sealing portion away from one part of the extruded weather strip, placing the one part of the extruded weather strip within a mold so that the lip is interposed between a heated mold member of the mold and one widthwise end edge of the covering layer in pressing contact therewith, and injecting a molding material into the mold to form a molded sealing portion in the one part of the weather strip from which the extruded sealing portion is cut away.
