The Integrated dual feed/IDT System
(Models 1536 and 1546)
PFAFF offers the ideal solution for sewing
dif cult materials: the integrated dual
feed. 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 cult materials such as silk and
rayon fabrics, the dual feed prevents seam
puckering.
Engaging the Integrated Dual feed
Important! For all sewing jobs with the
top feed, only use sewing feet with cutout
at the back.
Raise the presser foot. Then push the top
feed (17) downwards until it snaps into
place.
Disengaging the Integrated Dual Feed
Hold the dual feed with two ngers at
the marked places. Push the top feed (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.
