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. 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 keeps all layers of quilt
projects aligned to prevent stretching of the top layers.
Engaging the IDT
Important: For all work with the IDT, use presser feet with the center
back cut-out.
Raise the presser foot. Press the IDT (31) down until it engages.
Disengaging the IDT
Hold the IDT with two fi ngers at the ribbed ankle. Press the
IDT (31) down, then pull it away from you and release the IDT
slowly upward.
