Perfect stitch formation is when both looper threads meet at the fabric
edge. The needle threads form straight stitches for a stretchy and dura-
ble seam.
Thread tension
Thread tension should be properly adjusted to suit the various types of
work.
The ideal tension setting for most fabrics and threads is between 3 and 5.
However this can vary quite considerably when special threads such as
filament, woolly nylon, buttonhole twist (cordonnet), pearl yarn or deco-
rative threads are used. Only use decorative threads in the looper. The
thread must move easily and without resistance through the looper eye.
注意
Infinitely variable adjustments can be made from 1 - 9.
Turn the dial downwards for less tension.
注意
Turn the dial upwards for more tension.
注意
Adjusting the thread tension
Turn the tension dials by quarter or half number, then test sew again
and check the result.
