Preparations

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 down until it engages.

Disengaging the IDT

Hold the IDT with two ﬁ ngers at the ribbed ankle. Press the IDT down,

then pull it away from you and release the IDT slowly upward.
