3) Take-Up Spring
[CAUTION 2]
After adjusting the operating capacity of the
take-up spring, check if the spring connects
with the stopper.
①
Take-up Spring Functions
Difference in the length of the upper thread pulled by the take-up lever and pulled by the hook creates tension
or looping. When the tension is too weak, the take-up spring handles the leftover length of the upper thread.
Increase the tension or the stroke of the spring to form tight stitches on the embroidery.
②
Take-up Spring Adjustment
ⓐ
If the spring tension is too weak:
Turn the tension adjusting stud clockwise to
increase the tension.
ⓑ
If the spring tension is too tight:
Turn the tension adjusting stud counter-clockwise to
decrease the tension.
③
Adjusting stroke of the take-up spring:
To adjust the stroke of the spring during embroidery
work, move the take-up spring stopper to right or
left as shown in [Fig.5-16].
