What to do if the bobbin thread breaks all the time?
Comments
Finding the cause of the evil
Unfortunately, the one problem that causes the bobbin thread to break constantly does not exist. It is rather a problem that can have many causes. The most important of them will be summarized here:
- Coil is not positioned correctly in the coil housing
- Bobbin case (with bobbin) is not inserted correctly into the sewing machine
- There is a remnant of yarn in the bobbin housing
- Upper thread cannot bring the lower thread up properly
- Coil housing is dirty or damaged
- thread is too thin or old
- Thread is too tight (tension must always be adjusted to the new thread)
- Bottom thread was inserted the wrong way round
Advantages and disadvantages of tips against a tearing bobbin thread
- Coil housing can be cleaned to avoid problems
- use suitable threads
- Yarn residues can lead to problems
To fix the problem of the ripping underthread
Usually it is possible to identify the actual problem quite quickly. If you still do not see it immediately, it helps to proceed according to the exclusion principle. First of all, check that the bobbin is correctly seated in the bobbin case and the bobbin case is correctly seated in the sewing machine. Then check whether the thread is perhaps too tight and therefore always tears. If this is also not the case, it is quite possible that the thread is either too thin, of poor quality or even too old (“friable”). In this case it helps to simply insert a new (better) thread.
Step by step – how it works:
As you can see, it is by no means a reason to despair if the bobbin thread breaks frequently. It is important that you pay attention to the problem and do not simply accept it. Because one thing is certain: The thread does not break so often for no reason.
Once the problem has been solved, you will most likely have peace of mind for the time being. Nevertheless, check regularly that everything is correctly positioned in the sewing machine and that even small parts such as the bobbin case and the shuttle are clean (especially dust-free!).
Furthermore, it is always advisable to use high-quality thread. Even if cheap yarn in different colours is always very tempting, you will only have trouble with it.
Tip! Instead, invest in high-quality products. Then you can be sure that the thread will be much less prone to break constantly. Your nerves will thank you for it.
