3. Interlocking with Bobbin Thread The bobbin case, which holds the bottom thread, is designed to catch this loop. As the needle continues to move up, the loop tightens around the bobbin thread, creating the lock stitch. Once the loop is locked in place, the needle continues its downward motion, pulling the newly formed stitch tight against the fabric.

The double needle walking foot sewing machine is a specialized sewing machine that features a walking foot and two needles. The walking foot ensures that the top layer of fabric moves evenly alongside the feed dogs beneath, which is particularly useful when working with multiple layers or slippery materials. This mechanism helps to prevent shifting and puckering, resulting in beautifully finished seams.

Conclusion

The integration of industrial sewing machines and overlockers in textile production creates a seamless workflow that enhances overall quality and efficiency. In a typical manufacturing environment, garments are first sewn together using industrial sewing machines, followed by finishing touches with overlockers. This combination ensures that all seams are secure and visually appealing, meeting the high standards expected by consumers.
