The tension
for
each of
the thread
tension
dials should
be
different
according
to the
pattern stitches
as
in
the
chart
above.
Since
the
figures in
the chart
are for average
strength
of
thread
tension,
it may
be
necessary to
adjust
the thread
tension slightly.
Thread
tensions will
differ
according
to the kind of
fabric
and the thread.
The differential
feed
ratio is
normally “N”.
