2: Anatomy of a Sewing Machine
The picture shows the key parts of the business end of the sewing machine, the location, style and naming of other parts and controls we will leave to the sewing machine’s own manual.
- This penetrates, and feeds the upper thread(s) through the fabric.
- Presser Foot
- Often interchangeable, the presser foot holds the fabric in place whilst the needle is drawn in and out.
- Feed Dogs
- These serrated teeth draw the fabric through the machine to form the stitch. The greater the draw the longer the stitch.
- Throat Plate
- This plate supports the fabric as the needle penetrates through to pick up the bobbin thread underneath.
- The bobbin carries the lower thread. The version in the picture is a flat drop-in bobbin which requires a small section of the throat plate to be slid open so that it can be accessed and is known as a top loader. An alternative is a vertical bobbin which is mounted vertically and accessed through the front of the sewing machine and is known as a front loader. Front loading machines typically use bobbin cases into which the bobbin must be loaded before loading it into the machine.
