Why does my sewing machine bobbin bunch up?
If the thread has knots, is not smooth, is uneven, or is loose on the bobbin, then it has not been threaded correctly. If your machine uses a bobbin case, follow your sewing machine’s instructions to remove the bobbin from the case and re-thread it. Be sure that you have the bobbin thread engaged in the bobbin tension.
What should the tension be set on a Singer sewing machine?
The target figure should be around 30 to 40g. (1-1/4 to 1-1/2 oz) but it does not have to be too precise. However most people don’t have a spring balance handy, so alternatively you can tie a weight of the correct amount onto the thread and then jerk the bobbin gently upwards.
Why does my sewing machine keep jamming underneath?
However certain you are that the problem with the machine is most likely due to a huge tangled mess of thread in the bobbin underneath the fabric, the most common reason for the jamming is usually the lack of sufficient tension in the upper thread.
How do I know if my bobbin tension is correct?
The thread should unwind just slightly and the bobbin case should drop an inch or two. If the thread unwinds without resistance and the case slips to the floor, your bobbin tension is too loose. If the bobbin case doesn’t budge, your bobbin tension is too tight.
Why is my bottom bobbin not catching?
First, your needle may be dull or damaged and needs to be replaced. You should also check that you are using the correct needle for the type of fabric you are sewing. If the needle is not inserted correctly, it will not be able to pull up the bobbin thread and will cause skipped stitches.
Why is my bobbin not winding?
If your bobbin does not wind quickly and smoothly when you press on your foot pedal, your bobbin winder might not be fully engaged. This can cause uneven winding. Make sure you push your bobbin pin all the way over or loosen your bobbin wheel completely to engage your bobbin winding mechanism.
Why does my singer simple keeps jamming?
If your bobbin is threaded wrongly, it could cause jamming issues to your sewing machine. Your bobbin thread won’t move properly if there are knots or if the bobbin isn’t properly wound. Check to see if the threading on your bobbin is all tangled, and fix it if you can.
Why does my Singer sewing machine keep breaking?
If the upper thread is breaking, it could be that the thread path is obstructed, the machine is not correctly threaded or the upper thread tension is set to tightly. Be sure that the machine is correctly threaded and there are not obstructions (for example, thread getting caught behind the spool cap or a “rough spot” on the spool itself).
How many bobbins does a Singer sewing machine need?
Most SINGER sewing machines only come with 3 or 4 bobbins. We have found that 10-20 bobbins is about the right amount of bobbins a beginner sewist will need to get started. But, getting the correct bobbin is a must!
Why is my bobbin thread showing on my sewing machine?
If Bobbin Thread Is Showing on the Top of the Fabric This can be caused if the top thread tension is too tight, or if the bobbin thread is not in the bobbin case tension. Check that the upper thread is feeding freely without obstruction (like getting stuck behind the spool cap or getting caught on any rough spots o the thread spool itself).
