Prototypes of the modern sewing machine date back to 1755, when the first patent was awarded for a needle to be used for mechanical sewing. Since that time, different types of sewing machines emerged until the successful marketing of the Singer model in the late 19th century. From that point forward, sewing machines continued to evolve, develop features and revolutionize tailoring.
Sewing machines in Tuscaloosa, AL are now as complex or simple as you prefer. All of them work in similar ways to help you complete your creations. This overview will describe the primary elements of sewing machine operation to help you better understand how they work.
The loop stitch
The earliest sewing machines attempted to duplicate hand sewing. However, these proved inefficient as there was no way for a machine to emulate the movements of human hands. The solution was the internal loop stitch, which is still the mainstay of sewing machines today.
Using a bobbin of thread under the needle as well as a supply above it, the needle only needs to penetrate halfway through the fabric to create a stitch, allowing a stitch to be completed more quickly. As it does this, it loops with the bobbin thread to create stitches both above and underneath the fabric. This not only created a means for a machine to sew, but also offered a stronger seam. It soon became a viable alternative to hand sewing.
The electric motor
Sewing machine motors are fairly simple. They run on electricity and contain a series of drive shafts, belts, drive wheels and gears. There are not hundreds of tiny parts, and if something breaks down, the motor is easy to diagnose and repair.
The set-up also allows you to adjust thread tension. By moving a crank or turning a knob, you can tighten the tension when sewing thinner fabric, like silk, or loosen it if you are sewing a wool coat with a thick lining. A feed dog right below the needle will keep the fabric moving forward as you finish your seams. It is a very well synchronized system made for efficiency.
The foot pedal
Possibly the most revolutionary part of the sewing machine, the foot pedal controls all operations. Using pressure, you control the speed of your machine and can start or stop it in an instant.
The first sewing machines operated through a hand crank, which meant you only had one hand available to guide the fabric as you cranked the machine. Many tailors avoided these early machines because that process proved to be cumbersome. The idea of operating the mechanisms by using a foot pump instead of a crank revolutionized these early machines. A seamstress could now operate the machine with both hands free to manipulate fabric and monitor stitches. The manual foot pedal used a belt and drive train to move the mechanisms within the machine.
Now, rather than needing a pumping action to keep gears moving, modern foot pedals fire up the motor to move the system. Whether manual or electric, the process remains synchronized to combat any human error.
Sewing machine models are like cars in that each has its own features and feel. However, also like cars, they all operate the same way, meaning your chosen model will be a matter of personal preference.
