2. Aesthetic Appeal Overlocking leaves carpets looking professional and polished. The machine creates smooth, clean edges, enhancing the overall appearance of the finished product, which is especially important for retail settings.

2. Improved Stitch Quality Using the right needle for heavy fabrics ensures that stitches are even and robust, which is vital for the durability of the finished product.

At its core, the single needle lockstitch machine operates using a straightforward mechanism. It consists of two threads—a top thread and a bottom thread, typically wound on a bobbin. The top thread is looped through a needle, while the bottom thread is fed from the bobbin, which resides underneath the sewing plate. When the needle pierces the fabric, it creates a loop that intertwines with the bottom thread. This action produces a tight, secure stitch, which is the hallmark of lockstitch technology.
