Sewing machines are incredibly useful tools that allow us to efficiently turn fabric into clothing, bedding, and more. If you know how to use one, you can make a huge variety of useful items. However, it’s not just the machine itself that’s important; the way in which you use it and the accessories you use are just as crucial. One of the most important accessories to understand is the bobbin. So, what does a bobbin do on a sewing machine?
A bobbin is a spindle-shaped cylinder made of metal, plastic, or cardboard. Sewing machines come with one or two bobbin holders, depending on the machine. The bobbin holder, also known as the bobbin winder assembly, is located inside the machine. This is where you’ll place your bobbins when you’re ready to use them. Each bobbin consists of a core which is wound with thread. Some machines come with pre-wound bobbins, while others require you to wind your own.
The main purpose of a bobbin is to provide the bottom thread in a stitch. For example, when making a straight line of stitching, the bobbin provides the thread that goes underneath the fabric, while the top thread is provided by the top needle. This creates the classic lock stitch. Some machines are able to create more than one type of stitch which may require extra bobbins, or the use of pre-wound bobbins with different coloured threads.
When the machine is running, the bobbin is placed in the bobbin holder, and the thread is passed through a tension mechanism. This tensioning mechanism is used to adjust the amount of tension in the thread, so that when the bobbin is turned, it is pulled up by the bobbin case and the stitch is formed.
The bobbin holder is also often used to guide the thread around the edges of the material. This helps ensure the thread is in the right place and that the stitch is uniform and even. Without this, the thread would wander, which could lead to loose stitches or fabric puckering.
In addition to the basic uses outlined above, some machines can also use bobbins for other types of stitches, such as zig zags or decorative stitches. The user manual will tell you what type of bobbins are required for these stitches and how to use them.
When you’re using a sewing machine, it’s important to understand how the bobbin works and how it can affect the look of your finished project. If you’re unfamiliar with bobbins or the bobbin holder, it’s a good idea to read through your machine’s user manual to learn how to use them properly.
Tension
Tension is an important factor when it comes to sewing with a bobbin, and you’ll want to ensure that your tension is just right for the job. If the tension is too loose, the thread can become loopy; if it’s too tight, the thread can become knotted. Fortunately, most modern machines come with adjustable tension mechanisms, so you should always be able to get the perfect tension for your project.
The tension can be adjusted by turning the tension dial, which is usually located near the bobbin case. As you turn the dial, the tension will gradually get tighter or looser, so you’ll need to experiment a bit to find the right balance. As a general rule, you should start with the tension at its lowest setting, and then adjust it until the stitches look even.
It’s worth pushing the fabric against the bobbin case while you’re adjusting the tension, as this can really make a difference. You should also check the thread regularly to make sure it’s not too tight or too loose.
Bobbin Care
Bobbins do wear out over time, so you should always make sure you’re regularly checking them for signs of wear and tear. If you start to notice fraying or signs of rust, it’s time to replace the bobbin. This will ensure that the thread doesn’t become tangled or stuck on the bobbin.
It’s also important to know how to properly store your bobbins. The best way to do this is to keep them in an airtight container. This will prevent the thread from becoming damaged or tangled. You should also make sure that the threads are tied securely to the bobbin so that they don’t come undone.
Accessories
Many sewing machines come with additional accessories which can be used to make it easier to use the machine correctly. One such accessory is a bobbin threader, which can be used to help guide the thread through the bobbin holder. A threader is particularly useful for those who suffer from poor eyesight, or for those who are just starting out with sewing.
The bobbin case is also an important accessory when it comes to using a bobbin. A good case should be made of a durable material and should fit snugly into the machine. This will ensure that it doesn’t move around while in use, which can cause thread to become tangled. It’s also important to make sure that the case is clean, as dust and dirt can build up inside the machine, which can cause problems with the thread.
Conclusion
As you can see, bobbins are an essential part of a sewing machine and understanding how to use one properly can make a big difference to the way your projects look. By making sure the tension is adjusted correctly, your threads will be even and your stitches will look great. And, by ensuring that you store your bobbins correctly and regularly check them for signs of wear and tear, you’ll ensure that your machine works perfectly for years to come.
