A type of sewing machine equipped with a specialized presser foot system uniformly feeds multiple layers of fabric through the machine. This dual-feed mechanism, where the feed dogs work in conjunction with the moving presser foot, prevents shifting and slippage, a common challenge when working with thick materials, quilts, or slippery fabrics like leather or vinyl.
This feature offers significant advantages for projects requiring precise alignment and consistent stitching. It enhances the quality of seams on challenging fabrics, reduces the need for basting, and simplifies the creation of intricate designs. The development of this technology addressed the limitations of traditional single-feed systems, paving the way for more efficient and professional results in a wider range of sewing applications, particularly in quilting and leatherwork.
