Overview of Bobbin Mechanics
Using a sewing machine, especially at the beginner level, is all about understanding how the machine works and the different components of the machine. The bobbin is one such element, and although it may seem small, it needs to be kept in working order for a smooth needle movement during each stitch. Understanding how the bobbin works will help you to know how to troubleshoot and fix common issues when they come up.
Every sewing machine has a bobbin case, which is the fine piece of metal or plastic casing with an opening in the center where the bobbin is placed. The bobbin helps move the thread from the spool through the tension disk, carrying it to the needle every time you sew. It also helps form the lower thread in a stitch. Bobbins come in many different shapes and sizes depending on the type of machine and the age of the machine.
The bobbin should be wound with the right amount of thread, but not too much as this can cause problems with the tension when sewing. It’s also important to make sure the thread is wound evenly with no lumps or knots. Make sure the bobbin is set up correctly in the bobbin case before inserting it into the machine.
When inserting the bobbin, make sure it’s wound in the correct direction for your sewing machine and is inserted into the bobbin case with the thread coming off the top of the bobbin.
How to Fix Bobbin Adjustment Issues
If your stitches are not forming correctly, it could be due to a loose or tight bobbin tension. Most sewing machines come with an adjustable bobbin tension, you will find a dial or disc on the side of the machine that lets you adjust the bobbin tension. If the bobbin tension is too loose, your stitches might be loose, while if the bobbin tension is too tight, your stitches may be too tight.
If the bobbin tension is too loose, you can try turning the tension dial clockwise to increase the bobbin tension, and if the bobbin tension is too tight, you can turn the tension dial anti-clockwise to decrease the bobbin tension. To check if you’ve adjusted the bobbin tension correctly, you can sew a few stitches on a scrap piece of fabric and check the tension threads on the underside of the fabric. The upper and lower stitches should be even and tight.
If you’re having trouble adjusting the bobbin tension, or if you’re not sure how to do it, you can take your machine to a repair shop and let a professional adjust the bobbin tension for you.
Checking the Bobbin Case for Wear and Tearing
If your bobbin is not winding correctly or the thread is coming out of the bobbin case while you’re sewing, the bobbin case might be worn or damaged. You’ll need to check the bobbin case for wear and tear and replace it if necessary. To check the bobbin case, turn the machine off and unplug it, then check the bobbin case for any rough edges.
If there are any rough spots on the bobbin case, you’ll need to replace it. If the bobbin case is in good shape, you can clean it and oil it. To oil the bobbin case, use a small drop of oil and apply it only to the parts of the case that move.
When the bobbin case is clean and oiled, you’ll need to reinsert it into the machine. Make sure that the bobbin is inserted into the bobbin case in the correct direction and that the thread is coming off the top of the bobbin.
Cleaning the Bobbin
Sometimes, the bobbin can become dirty or full of thread, which can cause problems when sewing. To clean the bobbin, you’ll need to turn the machine off and unplug it. Take the bobbin out of the machine and check it for any lint or thread. If there is lint or thread on the bobbin, you can carefully remove it with a soft brush or a lint roller.
You should also check the thread on the bobbin and make sure it’s wound evenly and without any lumps or knots. If there are lumps or knots in the thread, you should rewind the bobbin before using it.
When the bobbin is clean and wound correctly, you can reinsert it into the machine and sew a few stitches to make sure the thread is running correctly.
Using the Right Bobbin for Your Sewing Machine
Using the correct bobbin for your machine is essential for the proper functioning of the machine and for avoiding bobbin-related problems. Different sewing machines require different types of bobbins, so make sure you are using the correct type for your machine.
When buying a new bobbin, look for the specific type for your machine as different types can be used in different machines. For example, there are different types of bobbin used in different brands of sewing machine, such as Brother, Singer, Janome and so on.
If you are still unsure what bobbin to use, you can take your machine to a repair shop and the technician will be able to tell you what type of bobbin your machine requires.
Sewing machines are complex machines and one of the most important components is the bobbin. The bobbin helps the thread move through the machine and keeping it in good working order is essential for successful stitching. If the bobbin is not functioning properly, you can troubleshoot and fix the issue by adjusting the bobbin tension, cleaning the bobbin and replacing the bobbin case, if necessary. Additionally, make sure you are using the right type of bobbin for your machine.
