One of the primary benefits of auto sewing is increased efficiency. Automated systems can operate continuously, significantly reducing production time. For instance, while a skilled worker might sew one garment in a specific timeframe, an auto sewing machine can produce multiple pieces in the same period. This efficiency not only meets the growing consumer demand for quick production but also allows brands to respond dynamically to market trends.

At the core of the double needle chain stitch sewing machine lies its unique threading system. Unlike conventional sewing machines that use a single needle and bobbin mechanism, the double needle machine operates with two needles threaded simultaneously. These needles penetrate the fabric and form a chain stitch, which is a type of stitch characterized by its interlocking loops. The two needles work in tandem to create parallel rows of stitching, resulting in a strong seam that can withstand stress and strain.

1. Walk Foot or Teflon Foot These feet help the leather slide through the machine without getting stuck. A walking foot uniformly feeds multiple layers of leather, ensuring even stitching, while a Teflon foot reduces friction for smooth movement.
