Cause

Bad thread (weak,
uneven thickness, poorly
twisted, old)

Right-twisted thread

Excessive thread tension

Tension imbalance
between upper and lower
threads

Excessive tension &
stroke on take-up spring

Inspection & Repair

Change thread

Change to left-twisted thread

Adjust tension

Adjust tension and stroke

Check the thread used

How to select thread

Select soft thread with
even thickness
Choose left-twisted
thread

Z-direction: left twist
