Bobbin Tension Theory
Bobbin tension is an important factor in the successful functioning of all sewing machines, including Janome models, and this article will teach you how to adjust it. First, it is important to understand what bobbin tension is and how it affects your work. When you’re sewing, the bobbin is the mechanism that produces tension on the bottom threads. To be effective, the tension between the top and bottom threads must be balanced; if the tension is too tight, the fabric will pucker or pull. If it’s too loose, the stitches will be loose or the threads could break. Bobbin tension is adjusted by a tiny screw or a dial on the back of the machine, and it’s important that you take the time to understand how it works before making any adjustments.
Why Is Adjusting the Bobbin Tension Crucial?
Sometimes the tension is too tight because the machine isn’t threaded properly, or the bobbin case isn’t installed properly. Although most machines are set to the factory setting, the tension may need to be adjusted depending on the type of thread, type of fabric, and the tension setting of the upper thread. If the tension is too tight, the stitches will appear tight and the fabric may curl up around the seam. If the tension is too loose, the stitches may be loose and the thread may break. Adjusting the bobbin tension requires some knowledge of how thread, fabric, and tension settings interact.
How To Adjust Bobbin Tension on Janome Sewing Machine?
The first step in adjusting the bobbin tension is to examine the tension setting. This is typically done by looking at the tension scale numbers; if the number is higher, the tension is higher. It is recommended to start with the number at the mid-range. If you have a pre-set tension screw, you can adjust the tension by turning it clockwise or counter-clockwise. If you have a dial to adjust the tension, make sure it is set to the correct number before threading the machine. However, if you are having trouble with puckering and breaking threads, you may want to experiment with higher or lower settings.
It is important to periodically check your machine’s tension, especially before beginning a new project, to make sure it is properly adjusted. This is done by threading your machine, placing a scrap piece of fabric onto the machine and turning the hand-wheel slowly to make sure the stitches look even and there is no evidence of the bottom threads being over-tensioned. If there are any signs of this, you can easily adjust the tension for your next project.
Troubleshooting & Maintenance
If you experience any problems with your sewing machine, such as puckering or breaking threads, it is important to examine the bobbin tension. If it is too tight, you can make adjustments as described above. Another important point to keep in mind is to keep your machine clean and oiled. This will help to ensure it is running in optimal condition, which is necessary for efficient stitching.
In addition, it is important to regularly change the bobbin case and the thread in your machine to ensure it is running smoothly. Old, worn or dirty thread can cause problems in your machine, so it’s best to start with a new thread every time. It is also important to use the correct bobbin case for your machine; if the bobbin case is not specific to your particular model, you run the risk of it not fitting properly or not functioning correctly.
Working with Special Fabrics
Finally, it is important to be aware of the fabric you are working with and how this may affect the tension. For example, lightweight fabrics, such as silk and chiffon, may require a higher tension setting as they can be more prone to puckering and breaking threads. Likewise, heavier fabrics, such as denim and canvas, may require a lower tension setting as they are more resistant to pulling and stretching. Before beginning a project, it is best to experiment with different tension settings to find the setting that works best for the fabric.
Using Tension Disks & Tests
In addition to adjusting the tension level on the back of the machine, you can use a tension disk to help you achieve more precise tension settings. A tension disk is a small, round disk which is inserted into the bobbin case and helps to tighten or loosen the bobbin tension as needed. This is especially helpful for more precise or intricate projects, or for those who are still learning about machine tension settings.
Another way to test tension settings is to sew a test seam on a scrap piece of fabric. This will allow you to make adjustments before beginning your project and ensure the tension is correct for the type of fabric and thread you are using. Additionally, if you’re unsure of the tension setting, you can take your machine to a professional for a professional adjustment.
Practice Makes Perfect
Learning how to adjust the bobbin tension on your Janome sewing machine takes practice, but it is an essential part of maintaining a well-functioning machine. Tension settings can affect the quality and appearance of your work, so it’s important to take the time to learn how to adjust it properly. Thankfully, adjusting the bobbin tension is a fairly easy process, and with a bit of practice and patience, you will be able to master it in no time.
Experiment & Adapt for Different Fabrics & Threads
Adjusting the bobbin tension will also depend on the type of fabric and thread you’re using, so it’s important to experiment with different tension settings for different fabrics. For example, for lightweight fabrics and delicate threads, the tension should be set lower than for heavier fabrics and threads. Conversely, for thicker materials, the tension should be higher to avoid the threads from breaking.
It is also essential to check tension levels on a regular basis. This way, you can detect any changes or problems early and avoid ruining a project. By regularly checking your machine and adjusting the bobbin tension when necessary, you can ensure that your sewing projects will turn out properly and your machine will run smoothly.
Thread Choices & Quality
Thread quality also plays a role in the success of your project, so it is important to use quality threads. There are a variety of types of threads available, ranging from polyester and cotton threads to more exotic blends. The choice of thread will depend on the type of project you’re doing, so it is important to select the best quality thread for the job. By carefully choosing quality thread, you can be sure that your project will turn out as intended, with minimal problems and maximum accuracy.
Combine, Use & Find Your Style
Once you’ve mastered bobbin tension adjustment, you can take the process to the next level by combining different fabrics, threads and tension settings. This will allow you to create unique, one-of-a-kind projects and add your own personal touch to your work. Furthermore, by experimenting with different techniques and fabrics, you can find your own style and develop your own techniques.
Summary
Adjusting the bobbin tension on your Janome sewing machine is an important part of keeping your machine running properly and producing excellent quality work. By taking the time to understand how tension settings affect your machine, you can ensure that your projects turn out as desired and that your machine remains in good condition. Additionally, it is essential to use quality threads and regularly check the tension settings on your machine, as this can have a direct effect on the quality and appearance of your work. Finally, by experimenting with different fabrics, threads and tension settings, you can find your own style and create unique projects.
