Tension & Looseness
Bobbins are a vital part of using a sewing machine. As the bottom thread of the machine, it’s usually where you’ll find the tension needed to make a secure and even stitch. When threading the bobbin, it’s important to regulate the tension of the bobbin properly – a lack of tension can cause loose stitching and puckering around the fabric. On the other hand, too much tension will result in abnormal tension around the fabric, which can easily become distorted.
Steps for Threading a Bobbin
When threading a bobbin, it’s essential to follow the individual machine’s instructions. Depending on the machine, the process can vary and there may also be unique features included with the machine.
First, it’s important to check the bobbin type that is needed – there are two types, Class 15 and L-Style. Class 15 are the standard bobbins used with most home machines and come in different shapes and sizes. The L-Style bobbins are used with industrial machines and are slightly wider and longer than the Class 15.
Next, take a length of thread that is long enough to thread the bobbin, machine and needle and make sure that the tail is securely fastened at the back of the thread. Now you can start threading the bobbin. Make sure that the bobbin is placed as instructed in the sewing machine’s manual.Carefully thread the needle from left to right and once the needle is thread, pull it back in a circular motion.
The thread must then be wound around the bobbin. There are usually two ways to do this in a sewing machine – manual or auto winding. For manual – make sure to hold the end of the thread in place and continue winding the bobbin until the thread is filled up. After, place the bobbin in the machine and repeat the process of threading the needle in a circular motion. For automated winding, the machine will hold the end of the thread in place automatically as the bobbin spins. Either way, this process should be repeated until the bobbin is full.
Adjustment of Tension
Once the bobbin is full, it’s necessary to adjust the tension of the bottom thread. Most sewing machines will have a tension regulator that should be adjusted prior to sewing. Adjust this according to the type of fabric you are using and the desired results. Generally speaking, thicker and heavier fabrics usually require a tighter tension. If the tension is too tight, it can cause puckering, while a looser tension can cause the fabric to pull away from the needle.
Cleaning the Bobbin Area
In addition to threading the bobbin, it is important to clean the surrounding are regularly. This means regular dusting, cleaning the lint and threads collected in the bobbin area. This not only helps maintain the performance of the machine but can also help prevent thread jamming.
Common Bobbin Threading Problems
It is quite common to experience some problems whilst threading a bobbin. One of the most common issues is thread jamming. This occurs when the bobbin thread and the top thread combine. The fix for this is to remove the bobbin case, re-thread the bobbin and then start the sewing process again. Another issue is skipped stitches, a condition in which the needle does not pull the bobbin thread up. This is usually caused by a loose bobbin and can usually be easily fixed by tightening the bobbin case.
Maintaining Your Sewing Machine
To keep your sewing machine in optimal condition, it is essential to maintain it regularly. This includes regular cleaning, lubrication and checking the tension of both the bobbin and top thread regularly. It is also important to use the right type of thread and needles for the fabric you are working with.
Bobbins of Different Types & Sizes
Bobbins are available in different materials, sizes and shapes. Generally speaking, metal bobbin cases are the most durable and can withstand high temperatures. Plastic bobbin cases, on the other hand, are usually cheaper and more lightweight and can be used in machine with a lower tension setting.
Advice from Experienced Sewers
Experienced sewers always emphasise the importance of threading the bobbin correctly. They recommend taking the time to study the instructions, choose the correct type and size of bobbin and adjust the tension properly. They also advise being consistent with the thread and using the same type of thread in the bobbin and spool for a better balance. Taking the time to maintain the machine and reading the manual can also make your sewing experience more enjoyable.
Hints & Tips
If you don’t know how to thread your bobbin, it’s important to locate the manual for your particular sewing machine. You can also watch videos and tutorials or ask experienced sewers to provide instructions or tips. Additionally, it is essential to practice threading a bobbin and adjusting the tension several times until you get comfortable with the process.
Accuracy & Patience
Above all, threading the bobbin correctly is essential for successful sewing. It’s necessary to be precise and patient and to check the tension regularly for the best results. Once the tension is correct and the bobbin is threaded correctly, you can perform basic and even more complicated stitching techniques with ease.
Fabric Choice & Thread Weight
Fabric choice is also an important factor when it comes to threading the bobbin. Lightweight fabric requires a lightweight thread weight, while heavier fabric requires a heavier thread weight. It’s beneficial to familiarise yourself with the different thread weights and familiarise yourself with the type of thread that is best for the fabric you are sewing with.
Threading & Quality of Stitching
Threading the bobbin correctly is essential for quality stitching. When it comes to threading the bobbin, the balance of tension between the thread and the bobbin is paramount. Too much tension will result in messy stitches, while too little tension will make the stitching weak and easily unravel.
Practice Makes Perfect
Threading a bobbin correctly takes practice and patience. It’s essential to take your time with the process and initially make sure to double-check your tension before sewing. Once you get comfortable with the process, it can become second nature and you’ll be threading your bobbins with ease.
