White 671 - Addressing Stitching Quality Issues

SKIPPED
STITCHES
A
bent
or
blunt
pointed
needle
is
often
the cause
of
this.
See
that
the
needle
plate
is
accurately
inserted.
(see
page
8) Remove
the needle
plate
and
after
ascertaining
that
the
feed
is
clean
and
working
freely,
replace
the
needle
plate.
NEEDLE
BREAKS
See
that
the
needle
is
not
bent
and
avoid
pulling
the
material
when
stitching;
either
condition
will
cause
the
needle
to
strike
on
the needle
plate
and
break.
MATERIAL
PUCKERS
This
is
generally
due
to
incorrect
tension.
See
that
both
the
bobbin
case
and
the
needle
are
properly
threaded;
that
the thread
used
is
of
good
quality
and
the
correct
size
for
the
needle.
(see
page
23)
STITCHES
LOOP
This
is
regulated
by
the
tensions.
(see
page
11)
See
that both
the
bobbin
case
and
the
needle
are
properly
threaded;
that
the thread
used
is
of
good
quality
and
the
correct
size
for
the
needle.
