Overlocking problem – wavy underside thread
Good Afternoon All,
I’m new here and have an Overlocking question.
I have a Yamato Industrial 5 thread overlocker.
In the picture, it shows the dark red thread having differing width stitches.
I have tried adjusting all 3 threads which compose the Overlocking edge.
What is in the photo is one complete run (much longer than the photo shows).
There was no change in speed or stopping/starting.
Can anyone help me?
Thanks in advance,
