ABSTRACT:
A mold for joining a molded portion onto an end of an extruded weather strip without having any looseness in the joint formed therebetween, and which facilitates removal of a fin formed in the molded portion. The mold includes mold members defining a cavity at an end of which an end of the extruded weather strip is placed, and to which a molding material is injected. The mold members further define a tunnellike additional cavity in a parting plane therebetween. The tunnellike additional cavity extends along a peripheral edge of the cavity so that an end thereof is located at the position beyond the end of the extruded weather strip. A passage is also defined in the parting plane so as to interconnect the cavity and the tunnellike additional cavity for introducing a molding material into the tunnellike additional cavity. The passage extends to a position close to but not beyond the end of the extruded weather strip.
