The built in Dual Feed/lDTSystem (Integrated DualTransport)
[
PFAFF offers the ideal solution for sewing difficult materials: the built in Dual Feed. This system
feeds the material from the top and the bottom simultaneously just the same as industrial sewing
machines. The fabric is fed precisely. On light or difficult materials such as silk and rayon fabrics, the
Dual Feed prevents seam puckering. The even feeding action also ensures perfect matching of
checked and striped fabrics.
