Differential
feed
The differential
feed
consists
of
two feed
dogs
(A
+ B),
arranged
one
behind
the
other,
which
move
the
workpiece,
Adjust
ment
lever
30
regulates
the
movement
of
the front
feed
dog
(A),
and
thus
the
amount
of
fabric
to be fed
through.
It
can
be adjusted
within
the
range
0.5
and
2.0.
The standard
adjustment
is
1 .0,
by
which
the
front
feed
dog (A)
moves
syn
chronously
with
the rear
feed
dog
(B),
i.e.
the
front and
rear
feed
dogs
both
move
the
same
amount
of
fabric.
Note:
The
effectiveness
of
the differential
feed
also
depends
on the
stitch
lenght
selected
and
the type
of
fabric
used.
If differential
feed
adjustment
lever
30
is
set
to
0.5, the
front
feed dog
moves
half
as
fast
as
the rear
feed
dog.
i.e.
the front
feed
dog
feeds
through
only
half as
much
fabric
as
the
rear
feed dog.
As
a
result,
the
fabric
is
stretched,
This
prevents
the
seam
from
becoming
gathered
when
sewing
very
delicate
fabrics
such
as silk
and
taffeta.
The
result
is
a
smooth
seam
(A).
Fashionable
touches
can
also
be
intro
duced
in
this
way,
such
as
the
wave
effect
when
using
rib
knit
(B).
