Thread Tension
3-thread fl atlock, narrow and wide
Stitch programs 13 and 14
If all thread tensions are set correctly,
thread looping is right at the edge of the
fabric. The upper looper (red) and the
needle (blue) meet at the edge of the
material. The lower looper (yellow) also is
at the edge as a straight piece of thread
along the edge.
The needle thread does not go all the way
to the fabric edge (too tight).
Adjust the needle thread tension (blue) to
a lower setting and/or the lower looper
thread (yellow) to a higher setting.
The upper looper thread (red) appears on
the underside of the fabric.
Adjust the red thread tension to a higher
setting and/or the needle thread (blue) to
a lower setting.
