First and foremost, it is essential to understand the component parts of a sewing machine. All machines have an upright shaft, arm, and table, usually made of plastic or metal, and the arm is equipped with a needle and the bobbin or shuttle carrying the thread. The needle is precisely guided by the mechanism of the machine, which consists of several components. The machine produces motion by means of belts and cams that are powered by an electric motor,which is itself connected to a power supply. The machine is operated by turning a hand-crank or a foot pedal, although some more modern machines are also operated electronically.<\/p>\n

The main components for a sewing machine consume the power generated by the motor. To produce stitch patterns, there is a needle bar, a stitch-forming device, and a feed-dog that is responsible for the movement of the fabric. The needle is the most essential part of the machine, as it is what forms the stitches. Its point moves in and out of the material while being guided by the “feed dog” – a combination of teeth that move the fabric in, behind and around the needle in order to produce the desired pattern. This mechanism works together with the cam and belt assembly, which controls the speed at which the needle moves.<\/p>\n

Once the needle has reached the fabric, the bobbin or shuttle takes the active role in the process. As the needle moves through the material, the shuttle carries the thread and creates a loop, by locking with the point of the needle. The loop is then secured by the closing of the needle which pulls the thread back bar, thus tightening the stitch. This is repeated every second or so to enable the stitch formation. Additionally, the tension must be controlled for even and strong stitches. This tension is produced by the shuttle, which is firmly held in place inside the bobbin-case that is equipped with a spring.<\/p>\n

A further essential element within the machine is the needle plate, which may contain holes or slots that aid the movement and keeps the needle in its optimal position. The needle plate’s tension is further regulated by a spinning wheel which adjusts when the material is placed in the sewing machine. The pressure can be adjusted depending on the thickness of the fabric and the desired length of the stitch. Meanwhile, a foot pedal gives the user control of the speed of stitch formation and the amount of pressure being applied. This lever also affects the tension of the shuttle, essentially creating a synergetic relationship between the two.<\/p>\n
