Adjusting
the differential
feed
The
differential
feed
prevents
interply
shift.
It
consists
of two
feed
dogs,
arranged
one
behind
the
other,
which
simultaneously
take
hold
of
the workpiece and move
it.
The
feed
amount
of either
feed
dog
can
be
set
separately.
It is
possible
to
have
the
workpiece
moved
more
by
the
front
feed
dog than
by
the rear
one, and
vice
versa.
Due
to
this,
very
good
sewing
results
are
achieved.
Set
the differential feed
according
to the
material
you
wish
to sew
(see
table
on
page 32).
The
following
settings
are
possible
using
button
16:
Setting
0.5
= Short
stroke
of front
feed
dog,
long stroke
of
rear feed
dog
Setting
—
= Same
stroke
of both
feed
dogs
Setting
1.5
= Long
stroke
of
front
feed dog,
short
stroke
of ear
feed
dog
to 2
The
differential
feed
is
infinitely
variable
from
0.5 to
2, also
during
sewing.
Note:
The
following
variants
can be
employed
to
obtain
fashionable
effects
on garments:
The
gather
effect
is
obtained
at
a differential
feed
setting
of
1.5
— 2
when
light
fabrics
are
sewn.
The
waved
effect
is
obtained
at
a differential
feed
setting
of
0.5 when
medium
to
heavy
elastic
fabrics
are sewn.
