    • An improved bow for a convertible top is described which is molded from a polymeric resin such as nylon and reinforced with glass fibers. The bow has a general I beam cross section and can be reinforced for additional strength. The ends of the bow can be configured to retain stay pads or tack strips. The bow can be molded in a set of tools that have interchangeable ends and retain the same mold for the central section of the bow. The interchangeable tools for producing the ends of the bow allow for greater manufacturing flexibility in that the central tool is retained for use in producing multiple styles of bows while expenses only have to be incurred for additional tooling for the ends of the bows.
    • 描述了一种用于可转换顶部的改进的弓形,其由诸如尼龙的聚合物树脂模制并用玻璃纤维增​​强。 弓具有一般的I梁横截面,并可加强以增加强度。 弓的端部可以被配置成保留垫片或钉条。 弓可以模制成具有可互换端部的一组工具,并且为弓的中心部分保留相同的模具。 用于产生弓的端部的可互换工具允许更大的制造灵活性,因为中央工具被保留用于生产多种类型的弓,同时只需要为弓的端部进行额外的工具的费用。
