How Does a Sewing Machine Work?
By Sharon Fabian
  

1     At one time, all mothers taught their daughters to sew. Today that is no longer true, and although almost everyone has seen a sewing machine, many people use one only rarely, if at all. Unless you're interested in a career in fashion design or sewing machine repair, chances are you haven't had much reason to use one. So you may not know that a sewing machine is a miracle of intricate, old-fashioned mechanical technology.
 
2     The main part is the needle, just as it is for hand sewing. Unlike hand sewing needles, however, a sewing machine needle has its eye, which is a hole for the thread, at the end near the point. The needle moves up and down to push a loop of thread down through layers of fabric where it attaches to another thread from the bobbin, which is located in the bottom of the machine.
 
3     The bobbin is inside another part called the shuttle. The shuttle holds the bobbin and rotates in sync with the movement of the needle above. It has a hook that grabs the top thread when it is pushed through the fabric by the needle. It loops the top and bottom threads together forming a tight lock stitch.
 
4     In order to have even, tight stitches, both the thread and the fabric must be held securely. To hold the thread, there is an assembly called the tension disc. Thread from a spool passes through the tension disc on its way to the needle. The disc can be tightened for sewing thin fabrics or loosened for sewing thick fabrics.
