The Idf System/Integrated Dual Feed - Top Feed - Pfaff tiptronic 2040 Instruction Manual

For sewing difficult materials PFAFF provides the ideal solution: the Integrated Dual Feed, IDF
system. As on industrial machines, the IDF feeds the fabric from the top and bottom at the same
time. The material is fed precisely. On light or difficult fabrics such as silk or rayon the dual fabric
feed prevents puckering of the seam. The even feeding action also ensures perfect matching of
checked and striped fabrics. The IDE keeps all layers of quilt projects aligned to prevent stretching
of the top layers.
