ABSTRACT:
Process and mold for joining two lengths of elongated composite sealing strips, for use on a vehicle body, in end-to-end relationship at a predetermined angle, each composite sealing strip being made up of a gripping portion to be mounted on the body and extrudedly made of compact plastics material, and of a sealing portion extrudedly made of cellular plastics material, the portions extending lengthwise of one another to form the sealing strips. The strip lengths are first cut crosswise at equal angles suitable to produce the aforesaid predetermined angle when the ends are in the aforesaid end-to-end relationship and the strip lengths are placed end-to-end with like portions in alignment. Welding plastics material is then injected over at least two of the aligned and like portions at the abutted ends and between the ends thereof whereby to weld the strip lengths together in one single operation. Thereafter, the injected plastics material is allowed to set.
