The article “How Sewing Machines Work” by Tom Harris explains the transformative impact of sewing machines, which have made clothing production faster and more affordable. The core mechanism of a sewing machine is the loop stitching system, which differs from hand-sewing by passing the needle only part-way through the fabric and using a series of gears, pulleys, and motors to create stitches.

There are various types of sewing machines, from basic electric models to advanced electronic ones. The article details two main types of stitches: the chain stitch, which is quick but not very sturdy, and the lock stitch, which is more durable and involves a shuttle hook and bobbin assembly to interlock threads. This technology has revolutionized the textile industry, making high-quality clothing accessible to many.
