TOWA Bobbin Case Tension Gauge for L style bobbin cases only, is designed for mid-arm and longarm machines. It measures bobbin thread tension for ideal stitch quality. Recommended settings are available on our Tension Guides for Longarm Machines. The TOWA Bobbin Tension Gauge makes it very easy to adjust bobbin tension by giving a numerical range to how tight or loose the tension is in a bobbin case.
To measure the tension of your bobbin, place your bobbin inside the bobbin case with the thread unwinding the correct way, then insert into the TOWA gauge. Pull your bobbin thread and guide it underneath the bottom wheel, over the top of the top wheel and then inside the catch. As you pull the thread to the side, you will see the top wheel move down while the numbers increase. The higher the number, the tighter the tension. To loosen the tension, turn the screw in small increments counter-clockwise. Think, lefty-loosy righty- tighty. We recommend making small adjustments when tightening or loosening the tension screw. Think of the screw as a face of a clock, when adjusting, adjust in 15 minute increments.
