Kegulating the Stitch SormatioM^
For
ordinary
stitching;
the
tension
on
the
upper
and
under
threads
should
be
equal,
and
just
sufficiently
strong
to
lock
both
threads
in
the
center
of
the
work,
as
shown
above (A).
If the tension on the needle is too tight, or if that on the bobbin thread is too loose,
the
needle
thread
will
He
straight
along
the
upper
surface
of
the
material,
thus
mak
ing an imperfect stitch,
as
shown
above
(B).
If the tension of the bobbin thread is too tight, or if that on the needle is too loose,
the
bobbin
thread
will
be
straight
along
the
under
side
of
the
material,
thus
making
an Imperfect
stitch,
as shown above
(C).
’ Regulating the Zension
A correct stitch can usually be obtained by
varying ^he tension on the needle thread.
AH adjustments should be made while the
presse” foot is down, since the automatic
release does not permit adjustments to be
made while the presser foot is up.
To
increase
the
tension,
turn
the
thumb
nut
on
the
tension
spring
toward
you.
To
lessen
the
tension,
turn
the
nut
in
the
opposite
direction.
The
thumb
nut
should
not
be
turned
abruptly,
but
regulated
little
by
little,
until
the
desired
tension is obtained.
The
quality
of
sewing
depends
on
the
thread.
Hence,
it
is
necessary
for
the
user
to
become
fully
familiar
with
the
correct
tensions,
through
practice.
