VIDEO: Sewing machine: bobbin thread tangled

If the bobbin thread becomes tangled or puckered on a sewing machine, it is usually because its tension is not in proportion to the tension of the upper thread. If the upper thread is too tight, then the bobbin thread will pucker and vice versa - if the bobbin thread is too tight, everything will pull together. However, this is often not due to the correct setting of the tensions of both threads, but rather to which thread or needle size you have chosen or which needle size you have chosen. how thick the fabric in question is.

Correctly thread the thread on a sewing machine

• If the upper thread is already passed through the wrong cutting disc, the entire upper thread tension is no longer correct and the lower thread becomes tangled or the upper thread breaks. So make sure you are using the correct thread guide.
• When it comes to the bobbin thread, the correct bobbin from the sewing machine manufacturer is often important. To do this, the bobbin must still be inserted with the correct side. On a Husquarna sewing machine, for example, the bobbin is marked with an engraving.

• Do not use spools of thread that are more than a year old. Thread rolls also get old and the threads are exposed to temperature fluctuations. Old threads tear easily.
• Clean your sewing machine at regular intervals. Torn threads, dust and other dirt are often stuck behind the bobbin winder. Use small tweezers and small brushes for cleaning and resin-free oil to oil the operating parts.

When the bobbin thread becomes tangled 

Of course, if the bobbin thread becomes tangled on your sewing machine, the first thing to do is to stop sewing. Be patient and careful when untangling so you don't break a delicate, thin fabric.

1. Twist the needle up and out of the fabric. Then take a longer sewing needle and bring the bobbin thread towards you. Cut the bobbin thread with a thread cutter or thin skin scissors.
2. Then try to pull the fabric out of the boat without forcing it. If this does not work, you have to reach for the thread cutter again and carefully cut further threads. After that, your fabric should be free.
3. Now loosen the remaining threads that have tangled with the bobbin thread until the fabric is "thread-free" again.
4. Now check: Was the fabric too thin for the needle used? Have the upper thread and bobbin thread tension been adjusted correctly? Was the fabric too thick for the needle being used? Have you used the correct foot for the previously set stitch? Have you set the right stitch pattern for the thickness of the fabric - for example, some stitch patterns cannot be used at all with thick fabrics.

Once you have sorted out and eliminated all possible sources of error, you can continue. Have fun.
