The Working Mechanism of a Sewing Machine

The working mechanism of a sewing machine involves several components working together to create stitches and sew fabric. The main working organ of a sewing machine is the sewing machine needle. The needle is responsible for piercing the fabric and creating loops of thread that form stitches.

Here is a breakdown of the working mechanism of a sewing machine:

1. Needle: The needle is a thin, pointed metal rod that moves up and down rapidly. It is attached to the needle bar, which is driven by the sewing machine's motor. The needle's sharp point pierces the fabric, creating a hole for the thread to pass through.

2. Thread: The sewing machine uses two threads: the upper thread and the bobbin thread. The upper thread is wound around a spool and passes through various guides and tension discs before reaching the needle. The bobbin thread is wound onto a bobbin and placed in a bobbin case located below the needle plate.

3. Feed Dogs: The feed dogs are metal teeth located beneath the needle plate. They move the fabric forward and backward as the needle stitches, ensuring a consistent feed of fabric. The feed dogs work in conjunction with the presser foot, which holds the fabric in place.

4. Tension Mechanism: The tension mechanism controls the tightness of the stitches. It consists of tension discs and a tension dial or knob. The upper thread passes between the tension discs, creating tension that determines the stitch quality.

5. Stitch Formation: As the needle moves up and down, it creates a loop of thread in the fabric. The bobbin thread is caught by a hook or shuttle mechanism, which forms a lock with the upper thread, creating a secure stitch. The fabric is moved forward by the feed dogs, allowing the needle to create a continuous line of stitches.

6. Stitch Length and Width: Sewing machines often have adjustable settings for stitch length and width. These settings determine the distance between stitches and the width of decorative stitches.

It's important to note that different types of sewing machines may have variations in their working mechanisms. However, the basic principles remain the same.
