ABSTRACT:
A method of joining end portions of a weatherstrip consists of introducing the end portions to openings in a mold such that a seal portion of the weatherstrip is compressed substantially to the shape of a seal lip of the seal portion. The end portions are separated in the mold by a predetermined gap and a rubber material is injected into the gap for mutually bonding the end portions of the weatherstrip. Such a method of joining allows the weatherstrip to be installed on complexly shaped openings with no degradation of sealing characteristics over the perimeter covered by the weatherstrip. A molding apparatus for joining said end portions includes a clamping member for assuring correct positioning of a sealing edge of the weatherstrip.
