At the heart of the modern sewing machine lies the chain stitch mechanism. This technology uses a series of interlocking loops created by a needle and a looper. The chain stitch is distinctive due to its ability to create a durable seam that is both flexible and elastic. Unlike traditional lockstitches, which require two threads to form a cohesive seam, chain stitches use only one thread in a loop, significantly reducing the amount of material needed. This not only lowers costs but also accelerates the sewing process, enabling manufacturers to produce garments at a remarkable speed.

- Built-in Stitch Options Depending on your projects, you may want a machine that offers different stitch types, including straight, zigzag, and decorative stitches.

Another user-friendly aspect is the variety of built-in stitches that these machines often offer. Heavy-duty sewing machines typically include a selection of stitches that can accommodate different sewing styles and techniques, from straight and zigzag stitches to buttonholes and decorative patterns. This versatility encourages creativity and makes it easier for users to experiment with different designs. Switching between stitches is usually straightforward, often accomplished with the simple turn of a dial or the press of a button.
