A device designed to be affixed to a sewing machine facilitates the application of pre-folded bias tape, fabric strips, or other decorative edging to the raw edge of fabric. This creates a clean, professional finish and prevents fraying. Different designs accommodate varying widths of binding material and can produce a range of decorative effects.
This mechanized approach offers significant advantages over manual binding techniques. It dramatically increases speed and efficiency, allowing for greater productivity. It also ensures consistent application and precise alignment of the binding, leading to a higher quality finish. The development and refinement of these devices have significantly streamlined the production process for various sewn items, from apparel to home furnishings.
