The IDT™ system
(Integrated Dual Feed)
For sewing any fabric precisely PFAFF®
provides the ideal solution: the Integrated
Dual Feed, IDT™ system.
As on industrial machines, the IDT™
system feeds the fabric from the top and
bottom at the same time at the same stitch
length. The fabric is fed precisely.
On light fabrics such as silk or rayon the
dual feed prevents puckering of the seam.
The even feeding action also ensures
perfect matching of checked and striped
fabrics. The IDT™ system keeps all
layers of quilt projects aligned to prevent
stretching of the top layers.
Engaging the IDT™ system
Raise the presser foot. Press the IDT™
system down until it engages.
Important! For all work with the
Integrated Dual Feed IDT™ system, use
presser feet with the center back cut-out.
Disengaging the IDT™ system
Hold the Dual Feed with two ngers at
the ribbed ankle. Press the IDT™ system
down, then pull it away from you and
release the IDT™ system slowly upward.
