3. Robust Construction Given the heavy-duty materials often used in baffle construction, these machines are built to endure rigorous use over long periods. They often feature sturdy frames and powerful motors, ensuring consistent performance in high-volume production environments.

The double needle stretch stitch utilizes two needles and a single thread from the spool, creating two parallel rows of stitching on the top side of the fabric. Meanwhile, the bottom side features a zigzag stitch that allows for stretch, ensuring that the seams maintain their integrity and do not break when the fabric is pulled or stretched. This unique combination of stitches makes it ideal for fabrics that require flexibility, as it allows for the functional benefits of a stretch stitch without sacrificing the aesthetic appeal of a straight stitch.

3. Metal Components Durability is crucial in heavy-duty sewing machines. Opt for machines with a metal frame and metal internal parts, as these are more robust than their plastic counterparts. A heavy metal base not only enhances stability during sewing but also prolongs the machine's life span.

1. Durability One of the primary advantages of utilizing an overlocking machine is the strength it provides to the seams of the carpet. Overlocked edges are less likely to unravel over time, ensuring the carpet retains its integrity even under heavy foot traffic.
