Upper tension regulator is a part of a sewing machine which is a dial or disk that controls the tightness (tension) of the upper thread.
Mechanism which controls delivery of upper thread.
The upper tension regulator on a sewing machine adjusts the tension on the upper thread. This helps ensure that the stitches are formed correctly and evenly, with the right amount of tension to hold the fabric layers together. Proper tension adjustment is important for producing high-quality sewing projects.
