ABSTRACT:
A belt weatherstrip which is adapted for engagement over an end flange of a vehicle. The belt weatherstrip includes a one-piece core member which has a backing leg, an intermediate leg and a show surface leg which generally form a U-shaped member having a width which fits over the end flange of a vehicle. An elastomeric coating is extruded onto portions of the core member for providing at least one sealing lip extending from the core member. A plurality of perforations formed in the intermediate leg allow expansion in the width of the perforated leg such that the width of the weatherstrip may be varied along the length of the weatherstrip during forming of the weatherstrip. In accordance with the method steps of the present invention a weatherstrip core blank is first provided and thereafter a plurality of perforations are formed in the blank along a longitudinal portion of the blank. A core shape is formed from the blank by stretch bending the blank along the central longitudinal portion having the plurality of perforations for varying the cross-sectional dimension at the plurality of perforations thereby facilitating formation of a weatherstrip having a varying width and cross-section dimension.
