A massive nest of tangled thread is usually a result of the sewing machine being improperly threaded. Just because the tangled mess is on the bobbin side of the stitching, don’t assume the fault lies with the bobbin. To correct this problem, put the presser foot up and unthread the sewing machine entirely.
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.
Why does my thread keep getting jammed?
The tension could be too tight or too loose. Set the tension to the basic thread tension setting or adjust the tension manually. The combination of the needle size, thread size and fabric is incorrect. Be sure to use the correct size needle and thread for the type of fabric that you are sewing.
Why is my bottom bobbin thread bunching up?
Your Bobbin Is Not Inserted Correctly
If you are getting bobbin thread bunching under your fabric, your bobbin might be inserted backward. Some sewing machines require your thread to go clockwise in your bobbin case, and some require it to go counterclockwise.
Why is my bobbin case keeps popping out?
The most common cause of this problem is when the bobbin holder’s finger isn’t placed in the small groove located in the needle plate. The best solution, therefore, is to ensure your bobbin holder finger is perfectly fitted in the needle plate.
What should sewing machine tension be set at?
The dial settings run from 0 to 9, so 4.5 is generally the ‘default’ position for normal straight-stitch sewing. This should be suitable for most fabrics. If you are doing a zig-zag stitch, or another stitch that has width, then you may find that the bobbin thread is pulled through to the top.
How do you fix bobbin tension?
To tighten your bobbin tension, turn the tiny screw on the bobbin case a smidgen clockwise. To loosen bobbin tension, turn the screw counterclockwise. A quarter turn or less is a good place to start.
