A sewing machine jam is when the machine gets locked up and cannot sew properly. This can be caused by several things, such as a thread getting tangled, the fabric not being fed evenly, or a build-up of lint or dust in the machine. Jams can also be caused by the needle hitting something inside the machine, so always keep an eye on the needle while sewing. If a jam does occur, it is usually relatively easy to fix by following the troubleshooting steps in your sewing machine’s manual or this article. However, if the problem persists, you may need to take your machine to a qualified repair person.
1. Incorrect threading: One of the most common reasons your sewing machine might be jamming is that the thread has been incorrectly threaded through the machine. This can cause several problems, including tension issues and skipped stitches.
2. Poorly-fitting bobbin: Another common reason for sewing machine jams is a poorly-fitting bobbin. If the bobbin is not seated correctly in the machine, it can cause many problems, including skipped stitches and tension issues.
3. Dirty needles: Sewing machine needles can become clogged with lint and dust over time, which can cause them to skip stitches or jam the machine. Be sure to clean your needles regularly to prevent this from happening.
4. Thread tension issues: If the thread tension on your sewing machine is too low, it can cause the thread to bunch up and jam the machine. Conversely, if the tension is set too high, it can cause the thread to break or snap. Be sure to adjust the tension according to the fabric you are sewing.
5. Poorly-oiled sewing machine: A machine not oiled correctly can also cause jams. Be sure to oil your machine regularly according to the manufacturer’s instructions.
