The TOWA Bobbin Tension Gauge is designed
for mid-arm and longarm machines. It measures bobbin thread tension to help you get the
ideal stitch quality. 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. Please refer to Superior’s Tension Reference
Guide for the recommended bobbin tension for all of Superior’s threads.
A tip for removing your bobbin from the TOWA gauge is to flip the gauge upside down and
pull the release tab on the bobbin case while lifting the Towa up. This ensures that the
bobbin comes out with the case.
