What is a Lock Stitch?

On the higher end of the market, you can find advanced zigzag sewing machines that cost anywhere from $600 to $2,000 or more. These machines are typically loaded with features such as computerized stitch selection, automatic needle threading, built-in embroidery options, and extensive presser foot attachments. They are designed for serious sewists who require precision and versatility in their sewing projects, including garment making, quilting, and crafts.

Moreover, walking foot machines can accommodate various types of stitches and sewing techniques. For instance, industries that require decorative stitching or intricate designs benefit from the machine’s adaptability, allowing for a range of applications without the need for multiple machines. This versatility reduces equipment costs and saves valuable space on the production floor, as fewer machines are required to achieve a wider variety of sewing tasks.

Lock stitch is a sewing technique that involves interlocking two threads—one from the needle and the other from the bobbin—to create a strong seam. This method is particularly advantageous for securing the seams of jumbo bags because it provides a tight, secure closure that can withstand significant tension and pressure. Unlike other stitching methods, lock stitch produces a consistent and uniform seam, reducing the likelihood of bag failure due to seam separation.
