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.
