1. Skipped stitches
Skipped
stitches
have
become
a
problem
in
recent
years,
especially
with
the
appearance
of
knit
fabrics
and
polyester
threads
on
the market. Skipped stitches normally can be
traced to four basic causes:
A. The Needle
B.
The needle is dull or bent. Change it.
The
needle
is
placed
incorrectly
in
the
needle
clamp.
It
is
either
backwards or the height is wrong.
The
wrong
type
of
needle
is
being
used
for
the
fabric.
Use
ball
point
needle
on
knits
and
wedge
point
needles for leathers and vinyls.
The thread is too thick for the size of
needle
being
used.
Use
a
larger
needle.
The Thread

(1)
The machine is threaded incorrectly.
(2)
Many brands of polyester thread are
too stiff and coarse thus making loop
formation
difficult
or
impossible.
Change
brands
or
use
a
cotton
thread.
C.
The Presser Foot
(1)
The foot being used is not holding
the
fabric
taut
enough
over
the
needle plate hole, thus the fabric is
being
pulled
up
and
down
while
stitching.
Use
the
foot
which
gives
the
most
control
possible
for
the
particular job being done.
(2)
There is not enough pressure on the
presser bar to hold the fabric firmly.
Increase
pressure
on
the
pressure
control.
D. The Fabric
The fabric has a heavy finish on it
which
deters
stitch
formation.
Wash
the fabric thoroughly before sewing.
If your machine skips stitches only on certain
fabrics, try all of the above procedures before
calling a repairman.
