Stitch

Fig. 19. Too Loose Needle Thread Tension
TO PREPARE FOR SEWING
Hold slack end
of
needle
thread
loosely
and
turn
machine pulley
over
toward
you
until
needle
moves
down
and
up
again
to
its
highest point, catching bobbin
thread.
• Draw up
needle
thread;
bobbin
thread
will
come
up with
it
through hole
in
throat
plate,
as
shown
in
Fig. 16.
• Lay both
threads
back
under presser foot.
• Close the
bed
slide.
•
Always
keep the bed slide closed
when the
machine
is
in
operation.
TO
START SEWING
• Move
take-up
lever to
top
of
its
stroke
as
shown
in
Fig. 8,
page
6.
• Place material
beneath
the presser foot. Lower
the presser foot.
Start
to sew, turning the machine pulley
over
toward
you.
TO TURN A CORNER
• Stop the machine when
needle
is
rising
but
before
it
is out
of
the material.
• Raise the presser foot.
•
Turn
material for next line
of
stitching, using
needle
as
a pivot.
• Lower the presser foot.
• Resume sewing.
• Avoid aiding the machine
by
pulling the fabric,
lest you
damage
the needle. The machine
feeds
the
work without assistance.
TO REMOVE
THE
WORK
• Stop the machine with the
take-up
lever
at
top
of
its stroke.
• Raise the presser foot.
• Draw the work
toward
the
rear
until
it
is
clear
of
the needle.
• Cut the
threads
close to the goods.
• Lay the
threads
back
under the presser foot.
THREAD TENSION
For
ordinary stitching,
tension on
needle
and
bob-
bin
threads
should
be
balanced with needle and
bobbin threads locked
in
centre of thickness of
material
as
shown
in
Fig. 17.
When there
is
too
much
tension on
needle
thread
and
not enough on bobbin
thread,
needle
thread
cannot
be
pulled down into material,
as
required. Poor stitching
results.
Needle thread will lie on top
of
material
as
shown
in
Fig. 18.
When there
is
too
much
tension on bobbin
thread
and
not enough on
needle
thread,
you
get
the reverse
of
the condition shown
in
Fig. 18.
The stitching
is
just
as
poor. The
bobbin thread will lie on bottom of mate-
rial
as
shown
in
Fig. 19.
