3) Take-Up Spring
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.

Take-up Spring Adjustment
�
Tension on the take-up spring affects the thread
tension. Turn the tension adjusting stud clockwise
to increase the tension and counter-clockwise to
decrease the tension.
�
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.5-15].
