glass.
IDT™ system (integrated dual feed)
For sewing any fabric precisely PFAFF®
expression™ sewing machine 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.
The material 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 shifting of the top layers.
Engaging the IDT™ system
Important: For all work with the IDT™ system, use
presser feet with the center back cut-out (D).
Raise the presser foot. Press the IDT™ system
down until it engages.
Disengaging the IDT™ system
Raise the presser foot. Hold the IDT™ system with
two ngers at the ribbed ankle. Pull the IDT™
system down, then pull it away from you to release
the IDT™ system slowly upward.
