The Integrated dual feed/IDT System
(Models 1538 and 1548)
PFAFF offers the ideal solution for
sewing dif fi cult materials: the IDT. This
system feeds the material from the top
and bottom simultaneously as is done in
industrial sewing machines. The fabric
is fed precisely. When sewing light or
dif fi cult materials such as silk and rayon
fabrics, the IDT prevents seam puckering.
Engaging the IDT
Important! For all sewing jobs with the
IDT, only use sewing feet with cutout at
the back.
Raise the presser foot. Then push the IDT
(17) downwards until it snaps into place.
Disengaging the IDT
Hold the IDT with two fi ngers at the
marked places. Push the IDT (17) down a
little and out to the rear, and let it move
slowly upwards.
The even feeding action also ensures
perfect matching of checked and striped
fabrics.
