Abstract

A method of manufacturing a weatherstrip is provided which includes the step of connecting a first extruded component and a second extruded component, each having surface treated portions and cut to a predetermined length, by means of a molded connecting portion which is molded by forcing molding material into the cavity of a mold defined by inserting and setting the first and second extruded components in the mold. The step of molding the molded connecting portion is performed by forming separating slits in a third extruded component which is cut to a length shorter that the length of the molded connecting portion and has surface treated portions such that these separating slits extend along the surface treated portions from both ends to an intermediate section and by setting the thus prepared third extruded component in the mold such that the surface treated portions are in line with the surface treated portions of the first and second extruded components.
