The built-in dual feed/lOT System (Integrated Dual Transport)
(Models
6122. 6152. 6232)
PFAFF offers the ideal solution for sewing difficult materials : the built-in dual feed. This system
feeds the material from the top and bottom simultaneously as is done in industrial sewing
machines. The fabric is fed precisely. When sewing light or difficult materials such as silk and
rayon fabrics, the dual feed prevents seam puckering.
