The Idt (Integrated Dual Feed) - Pfaff creative 2124 Owner's Manual

The IDT (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 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 keeps all layers of quilt
projects aligned to prevent stretching of the top layers.
Engaging the IDT
Important: For all work with the Integrated Dual Feed IDT, use
presser feet with the center back cut-out.
Raise the presser foot. Press the IDT (20) down until it engages.
Disengaging the IDT
Hold the Dual Feed with two fi ngers at the ribbed ankle. Press
the IDT (20) down, then pull it away from you and release the
IDT slowly upward.
