The sewing machine it is certainly one of the most used tools, but it often happens that its operation is not perfectly known.
Now let’s find out how it happens, so as to have that much appreciated general overview and able to offer a complete knowledge of this article.
The sewing machine and its parts
Before analyzing its operation, it is necessary to know the different parts that make up this instrument.
First of all we must talk about the bobbin, it is the part where the thread must be put which will be used for sewing.
Thanks to this, in fact, the thread is sent to the needle which makes it possible to carry out the different stitches on the fabric.
The second important part of the sewing machine is undoubtedly the thread tension system.
This, in fact, makes it possible to have the thread taut enough, so that the above does not break and at the same time there is also the possibility of preventing the stitches from being skipped.
We then move on to analyzing the machine needle.
It is the tool which, by piercing the fabric, allows the insertion of the different points, so that the seam can be applied easily.
The lever that allows you to select the sewing program is also very important: every self-respecting professional tool has several programs, each of which is adapted to a specific type of sewing.
Finally, there is the pedal which, by activating the motor, allows the sewing machine to work properly.
How the sewing machine works
After placing all the different pieces in the sewing machine and turning on the little light that allows you to see how the stitches are placed in the fabric, the key operation that activates the sewing mechanism is pressing the foot pedal. the tool.
When this simple operation takes place, immediate mechanisms are triggered which allow the work to be carried out on the fabric.
First, the needle is activated, which, descending towards the fabric, places the first stitch and, collecting the underlying thread, inserts the second.
At the same time, the tension system slides the thread while the surface where the spool sits turns on itself, effectively unwinding the thread.
In this way it is possible to sew perfectly, since the material used to make the stitches is delivered to the needle which, together with the action of the pedal, allows the sewing to be carried out.
Obviously, the movement of the fabric must be accompanied by that of the hands, which must slide so that it is possible to insert the various stitches and to carry out the seam.
After a piece is finished, you need to cut the thread, reinsert it into the needle and proceed to choose the appropriate program for a job.
The importance of precision and maintenance
Considering how this machine works, you should always remember that proper maintenance helps to create perfect seams and prevent the work done from being inaccurate.
Basically, it takes a fundamental tone to check the condition of the needle, the tension system, the positioning of the bobbin and the mechanism that allows it to turn and the quality of the sewing thread.
With careful control and maximum precision when inserting these parts and setting up the machine, you will be able to sew without particular difficulty.
What does mechanical sewing machine mean?
The main difference between an electronic sewing machine and a mechanical one is the method that is used for modifying or selecting the stitches: the mechanical machine is equipped with a lever or a button that mechanically allows to choose which stitch to use and another lever to change the length or width of the stitch.
