Sewing Machine

A sewing machine is a mechanical device equipped with a needle (or needles) threaded at the point-end, which puncture the fabric periodically as it moves under the needle; each stitch is created as the thread loops onto itself (chain stitch) or locks around a second strand of thread (lock stitch), sewing the fabrics together. Sewing machines are used in both the home and industry, but are designed differently for each setting. Those for the home tend to be more versatile in terms of the number and kinds of stitches they can perform, but they operate more slowly than industrial machines, and have a shorter life span. Industrial machines are heavier, have a much longer life span, are capable of thousands of stitches per inch, and may be designed for very specialized tasks.
