[
The
built
in
Dual
Feed/IDT
System
(Integrated
Dual Transport)
[
PFAFF offers
the
ideal
solution
for
sewing
difficult
materials:
the
built
in
Dual
Feed.
This
system
feeds
the
material
from
the
top
and
the
bottom
simultaneously
just
the
same
as
industrial
sewing
machines.
The
fabric
is
fed
precisely.
On
light
or
difficult
materials
such
as
silk
and
rayon
fabrics,
the
Dual
Feed
prevents
seam
puckering.
The
even
feeding
action
also
ensures
perfect
matching
of
checked
and
striped
fabrics.
