Abstract: This invention relates to decorative ribbons, and to methods and machines for making them. More specifically, the invention relates to fabric ribbons that are edged with wire and trimmed with an overlay of decorative thread.According to the invention, a run of fabric ribbon is simultaneously edged with wire and tightly bound with a binding filament (such as monofilament) and a trim filament (such as decorative thread). This is done in a single operation. The result is a unique ribbon construction, which has many desirable properties. The new ribbons are flexible, but will retain their shape when bent, twisted or tied into a desired configuration. They are elegantly simple in design and provide a novel streamlined finished product with components that are firmly bound together. The ribbons provide an improved edge and trimming where the wire meets the fabric.
