DIFFERENTIAL
FEED
The
differential
feed
prevents
wavy seams
in
knitted
fabrics and
also
movement
between
the
layers
of
fabric.
It
also
ensures
pucker-free
seams
on
lightweight
fabrics.
[DIFFERENTIAL
FEED
MECHANISM]
There
are two
sets
of
feed
teeth,
one
front
and
one
rear.
The
two
sets
of
feed
teeth
move
independently.
Differential
feed
allows
the
two
sets
of
feed
teeth
to
move
at
different
rates.

[ADJUSTING
THE DIFFERENTIAL
FEED]
The
differential
feed
can
be

of
the
differential
feed
can
be

sewing
without
