Bobbin Winder

Usually situated at the top-right corner of your sewing machine, the thread winder performs precisely what its name suggests – winding the thread onto the bobbin.

Each bobbin winder also has a bobbin winder stopper that stops the bobbin from winding when the bobbin is full and ready for your next sewing project. 

Your machine should have a bobbin winder thread guide in the manual so you can see exactly how to wind your bobbin. 

Bobbin

The bobbin is a small spool positioned underneath that holds the lower thread. To create a stitch, the bobbin thread and the needle thread are looped together in a synchronized manner.

Your machine should come with an empty bobbin. I also purchase more on Amazon and fill threads I am using a lot of so that I don’t have to stop and wind more bobbin in the middle of a sewing project. 

Each bobbin also has a small hole that you will place your thread through to ensure the thread tension stays consistent while you are winding your bobin. 

Bobbin Case

The bobbin case contains the bobbin and provides tension to the lower thread. As the needle thread is pulled around the bobbin case, it intertwines with the bobbin thread and draws it up through the needle plate.

Moreover, starting and stopping the sewing machine is effortlessly achieved with the push of a button.

Power Switch

The sewing machine is powered by an electricity-supplying power cord, which must be securely connected to the machine to maintain a constant flow of power. To control the electrical supply, the power switch is used for switching the sewing machine ON and OFF.

Stitch length adjustment:

Stitch length directly influences the size of the stitches created during sewing. On the machine, you can typically adjust the stitch length within a range from 0 to 4, where 0 represents the shortest stitch and 4 the longest.

The stitch length adjustment occurs at the feed dog rather than the machine needle. When you shorten the stitch length, it reduces the distance the fabric is fed under the presser foot before the needle descends.

Conversely, lengthening the stitch size allows more fabric to be fed under the presser foot before the needle comes down.

Tension Discs

Thread tension is responsible for determining how loose or tight the stitches are when sewing. Tension disks play a crucial role in controlling the pressure applied to the thread, ensuring a consistent feed to the machine needle. The primary functions of the tension device include:

1. Positioning the thread accurately to the needle.

2. Regulating the flow of the thread.

3. Maintaining smoothness in the stitching process.

4. Precisely controlling the passage of the thread.

There are two types of tension devices: direct tension device and indirect tension device. Both types consist of components such as (a) pressure disk, (b) tension spring, (c) thumb nut, (d) tension mounting bar, and (e) pressure releasing unit.

Modern high-speed sewing machines often feature a tension dial with graduated numbers for adjusting the tension.

Higher numbers on the dial indicate greater tension, while lower numbers signify reduced tension. Properly adjusted tension results in a straight and even stitch line on both sides of the fabric.

Thread Take-up Lever

The take-up lever is an integral component of the thread system in a sewing machine, strategically positioned directly above the presser foot.

Its role is crucial in the stitching process, as it plays a dynamic part in creating each stitch. After the needle pierces the fabric and forms a loop, the take-up lever rises to pull the thread back up out of the cloth, securing the stitch and allowing the needle to reset for the next cycle.

This continuous up-and-down motion of the take-up lever is what ensures the proper tension and alignment of the thread during sewing.

It contributes to the overall stability and consistency of the stitches, resulting in clean and even lines throughout your sewing project.

Beyond its primary function in the stitching process, the take-up lever also serves as a valuable gauge for monitoring your needle’s position.

As the lever moves up and down with each stitch, it provides a visual cue of the needle’s current location. This information is particularly useful when you need to stop stitching precisely at a specific point or align the fabric accurately for intricate sewing tasks.

Understanding the role of the take-up lever empowers you to optimize its performance and maintain your sewing machine in top condition.

Regular cleaning and lubrication of this mechanism will ensure smooth operation and prevent any potential issues that could arise from accumulated dust or debris.

With the take-up lever working harmoniously with the rest of your sewing machine, you can embark on your creative sewing endeavors with confidence.

So, the next time you see the take-up lever gracefully moving up and down, appreciate its vital contribution to the art of sewing and the beauty it brings to your crafted creations.
